Ecommerce SEO is won at the template level. You're not optimizing ten pages - you're optimizing category and product templates that generate thousands of URLs, plus faceted navigation that can either capture long-tail demand or bury Google in crawl waste. Pick the wrong agency and you'll either tank rankings with a botched migration or pour budget into pages that never convert.
If you already know you want to hire rather than compare agencies, see our ecommerce SEO services.
Heading into 2026, the best ecommerce SEO agencies tie work to revenue, not keyword positions. They know your platform's quirks - Shopify, BigCommerce, Adobe Commerce, WooCommerce, or headless - and they're building for AI Overviews and agentic commerce, where product discovery increasingly happens inside AI assistants rather than blue links.
We reviewed ecommerce SEO agencies across catalog sizes and platforms, weighing technical depth, content and CRO capability, transparent revenue reporting, and proof. These are the 17 we'd shortlist, sorted below by platform so you can skip the ones that don't run your stack. No one paid for placement. Verify pricing, platform fit, and case studies for your category before signing.
How we evaluated these ecommerce SEO companies
We ignored logo walls and looked at the things that decide whether a catalogue grows or stalls.
Category page strategy
Category and collection pages carry most of the commercial intent in ecommerce and are usually the thinnest pages on the site. We looked at whether agencies treat them as a priority or an afterthought.
Technical depth at scale
Faceted navigation, crawl budget, pagination, canonical logic and index bloat. These decide whether a large catalogue is discoverable at all, and most agencies are weaker here than they claim.
Platform fluency
Shopify, WooCommerce, Magento and BigCommerce each break differently. We checked for genuine platform-level knowledge rather than a logo on a partners page.
Product and feed handling
Out-of-stock logic, product schema, variant management and merchant feed hygiene. Getting these wrong quietly erases rankings you already earned.
Internal linking at scale
Manual linking does not work across thousands of URLs. We looked for systematic approaches that survive a catalogue change.
Revenue reporting
Whether the agency reports on organic revenue and assisted conversions, or on rankings and traffic that never reach a checkout.

Ecommerce SEO and AI visibility built for product and category growth
Full disclosure - this is us. We put ourselves here because ecommerce SEO is changing fast: shoppers increasingly start product research inside ChatGPT, Perplexity, and Google AI Overviews, and most agencies are still optimizing only for the ten blue links. We work on the full stack - technical SEO for large catalogs, category and product page optimization, content, and the entity and brand-mention signals that get stores cited in AI answers.
We are not an ecommerce-only shop, but the way we run SEO fits online retail well: fix crawl and indexation at catalog scale, win the high-intent category and comparison queries, and build the off-site authority that compounds. Across 70+ long-term partnerships in SaaS, fintech, and B2B tech, the throughline is durable organic growth - and we bring that same foundations-first discipline to ecommerce brands that want traffic that converts. For brands based in California, see our pages on ecommerce SEO in Los Angeles and ecommerce SEO in San Francisco.
They treated our catalog like an engineering problem and our brand like an authority problem at the same time. Rankings improved, and we started appearing when people ask AI assistants what to buy.
What clients sayWhy choose The Business Rover:
- Technical SEO for large catalogs and faceted navigation
- Category and product optimization tied to buying intent
- AI-visibility and entity work so stores get cited in AI answers

Their approach maps intent to site architecture, strengthens internal links, implements metafield-driven schema, and builds answer-ready content for both Google and AI search - including GEO and AEO tuned for agentic commerce. For ecommerce brands that want a specialist fluent in their exact platform and focused on category and product growth, 1Digital is a strong, focused pick.

Catalog-driven ecommerce SEO with CRO, dev, and analytics in-house
OuterBox is a long-established ecommerce agency that pairs SEO with technical implementation, CRO, analytics, and content under one team. Their strength is catalog-driven brands - the kind with deep category trees and thousands of products where prioritization is half the battle.
Because they can design, develop, and optimize, they're useful when the growth problem spans both marketing and site architecture. They are also one of the few agencies here with a public track record on complex replatforms, which matters if a migration is already on your calendar. For ecommerce brands that want SEO connected to development and conversion rather than handed between vendors, OuterBox is a capable, proven choice.
Catalog brands credit OuterBox for prioritizing the category and product opportunities that actually move revenue. Having SEO and development on one team is the recurring reason they avoid vendor finger-pointing.
What clients sayWhy choose OuterBox:
- SEO, development, and CRO handled together
- Strong prioritization for large catalogs
- Long track record across ecommerce platforms
Revenue-led ecommerce SEO with disciplined keyword prioritization
Searchbloom is a revenue-focused SEO and PPC agency known for strong keyword mapping, prioritization, and paid-organic alignment. They keep their client roster lean to ensure senior attention, and ecommerce brands consistently praise the collaborative, results-led approach.
Their discipline shows in how they sequence work - going after the category and product opportunities with the clearest revenue impact first. They are also one of the few agencies at this level that publicly offers month-to-month terms rather than a 12-month minimum, which is worth asking about if you've been burned before. For ecommerce brands that want focused, transparent execution and SEO that coordinates with paid, Searchbloom is a highly reviewed, dependable pick.
Ecommerce clients describe Searchbloom as focused and collaborative, with reporting that ties back to revenue. The prioritization discipline and senior attention are the recurring highlights.
What clients sayWhy choose Searchbloom:
- Disciplined keyword prioritization by revenue impact
- Paid and organic coordinated together

Ecommerce-specialist SEO for DTC and retail brands
NOVOS is an award-winning, ecommerce-specialist SEO agency that works almost exclusively with online stores and DTC brands. Their entire model is built around ecommerce-specific thinking - product and category optimization, digital PR for retail, and organic growth tuned to how shoppers actually search.
That focus means they don't apply a generic SEO playbook to stores. Their weak spot is the mirror image of their strength: consumer retail is where they shine, so an industrial B2B catalog with no brand story is a poor match. For DTC and retail brands, especially in the UK and Europe but increasingly global, that want a partner who lives and breathes ecommerce SEO, NOVOS is a strong, specialized choice.
DTC brands praise NOVOS for ecommerce-specific thinking that generalists lack. The product and category focus, plus retail-tuned digital PR, are the recurring reasons stores choose them.
What clients sayWhy choose NOVOS:
- Ecommerce-only specialization, not a generic playbook
- Strong digital PR tuned for retail
- Award-winning organic growth for DTC brands
Ecommerce SEO, PPC, and paid social with a senior-team model
Inflow is an ecommerce-focused agency offering SEO, PPC, and paid social with a senior-led team model - no junior handoffs. They've built a reputation for digging into the technical and content fundamentals that move organic revenue for established stores.
Their integrated approach means SEO and paid are coordinated rather than siloed, which matters when organic and paid compete for the same terms. They tend to be strongest when a store already has traffic and the job is converting more of it, rather than building demand from zero. For established ecommerce brands that want senior specialists and SEO connected to their paid strategy, Inflow is a credible, experienced option.
Ecommerce clients value Inflow's senior team and the way SEO and paid are coordinated. The hands-on, experienced attention is the recurring reason established stores choose them.
What clients sayWhy choose Inflow:
- Senior-team model with no junior handoffs
- SEO and paid coordinated rather than siloed
- Strong technical and content fundamentals
Ecommerce SEO with strong design and development capability
Coalition Technologies is a data-driven agency that pairs SEO and PPC with serious web design and development, which makes them especially useful for ecommerce brands on Shopify, BigCommerce, and custom builds. When growth is blocked by site architecture as much as marketing, having both in-house helps.
They work across platforms and combine technical execution with content and conversion work, with reported engagements commonly landing in the $2,500 to $7,500 per month range. For ecommerce and mid-market brands that need design, development, and SEO coordinated rather than fighting each other, Coalition is a capable, well-reviewed choice.
Ecommerce clients value Coalition for combining technical web work with SEO. Having development and optimization on one team is the recurring reason brands avoid the usual vendor handoffs.
What clients sayWhy choose Coalition Technologies:
- Design, development, and SEO under one roof
- Strong platform expertise across Shopify and more
- Useful when technical site issues block growth
Engineering-led Adobe Commerce and Magento SEO for large catalogs
IWD Agency has shipped on Magento since 2009 and now runs Adobe Commerce, Shopify Plus, and BigCommerce work out of Austin with teams in Barcelona, São Paulo, and Warsaw. Their SEO position is refreshingly blunt: on Adobe Commerce, most organic problems are engineering problems. Layered navigation spawning filter URLs nobody will ever rank, canonical and pagination defaults splitting authority, and templates too heavy to pass Core Web Vitals do not get fixed by a meta-tag checklist.
They hold Adobe Solution Partner status and keep SEO inside the same team that writes the code, so a crawl-control decision doesn't sit in a dev backlog for three sprints. They are the least content-heavy agency on this list, so pair them with a content or digital PR partner if authority is your real gap. For Magento and Adobe Commerce stores where the platform is the ceiling, they're the sharpest pick here.
Enterprise merchants credit IWD for fixing organic problems other agencies could only describe. Having Adobe-certified engineers own both the diagnosis and the code change is the recurring reason Magento brands stay on retainer after launch.
What clients sayWhy choose IWD Agency:
- Adobe-certified engineers doing the SEO work, not handing it off
- Deep experience with layered navigation and multi-store catalogs
- Strategy, build, and optimization stay with one accountable team
Process-driven SEO with transparent execution for online stores
Victorious is an SEO-focused agency known for a structured, transparent process and a singular focus on organic search. For ecommerce, that means competitive analysis, keyword strategy, category and product content, and technical fixes, delivered with the clear reporting clients consistently praise.
They're not ecommerce-exclusive, but their disciplined methodology works well for stores that want a dependable SEO partner with accountability. Because they don't build or develop, you'll still need a dev resource for anything that touches the theme. For ecommerce brands that value process and transparency over big promises, Victorious is a reliable, highly reviewed option.
Clients highlight Victorious for transparency and process discipline. The clear methodology and honest reporting are the recurring reasons stores trust them with organic.
What clients sayWhy choose Victorious:
- Structured, transparent SEO process
- Singular focus on organic search
- Strong reviews and clear reporting
Shopify-specialist SEO and growth for ambitious stores
Eastside Co is a Shopify-specialist agency that combines store design and development with SEO and growth marketing. Their deep Shopify and Shopify Plus expertise makes them a natural fit for brands building or scaling on that platform who want SEO baked into the build rather than bolted on later.
Because they live in the Shopify ecosystem, they understand the platform's SEO quirks - forced URL patterns, app script bloat, collection duplication, and theme limitations - better than a generalist. For Shopify and Shopify Plus brands that want platform-native SEO plus development, Eastside Co is a strong, focused choice.
Shopify brands value Eastside Co for platform-native expertise. Knowing the SEO quirks of themes, apps, and URL structures is the recurring reason Shopify stores choose them over generalists.
What clients sayWhy choose Eastside Co:
- Deep Shopify and Shopify Plus specialization
- SEO baked into the build, not bolted on
- Understands platform-specific SEO quirks
Shopify Plus technical SEO, replatforms, and agentic commerce readiness
Netalico is a Shopify Premier Partner built around mid-market and enterprise DTC brands, roughly the $2M to $50M GMV band. Founder Mark Lewis came up through engineering, and the agency has spent more than a decade on the unglamorous half of ecommerce SEO: replatforms off Magento and BigCommerce, theme and app cleanup, structured data, and the site-speed work that decides whether a Shopify store passes Core Web Vitals.
They also publish openly about agentic commerce and AI visibility, which is a fair signal they're thinking about where product discovery is heading rather than only where it has been. The team is small and US-based with no offshoring, so they suit brands that want senior attention on a technical Shopify SEO problem more than anyone shopping for a large content engine.
DTC brands describe Netalico as the team that finally made a messy Shopify build behave. The migration track record and in-house engineering are the recurring reasons merchants keep them on retainer long after launch.
What clients sayWhy choose Netalico Commerce:
- Shopify Premier Partner with a decade of replatform experience
- Engineering-led team that ships the fix instead of documenting it
- Structured data and AI-visibility work already on the roadmap
Conversion-focused growth that makes ecommerce traffic pay off
The Good is a conversion rate optimization specialist for ecommerce, and while not a pure SEO shop, they belong on any list where organic traffic needs to convert. They run rigorous research and testing to fix the leaks between a visitor landing and actually buying - which is where a lot of SEO budget quietly dies.
Pairing their CRO with an SEO partner (or their broader services) means traffic gains turn into revenue rather than bounce. If your organic visibility is genuinely low, hire an SEO team first and bring The Good in once there's enough traffic to test against. For ecommerce brands that have traffic but weak conversion, they're the specialist that makes the rest of the funnel worth it.
Ecommerce clients credit The Good for fixing the leaks that wasted their traffic. The research-led CRO approach is the recurring reason brands pair them with SEO to make growth pay off.
What clients sayWhy choose The Good:
- Rigorous, research-led conversion optimization
- Turns organic traffic into actual revenue
- Deep ecommerce UX and testing expertise
Full-funnel ecommerce growth connecting search to revenue and LTV
Darkroom is a full-funnel ecommerce growth agency that integrates paid media, performance creative, retention, Amazon, TikTok Shop, CRO, and analytics - with SEO and organic fitting into a broader revenue picture. They manage significant annual revenue for DTC and CPG brands and run AI-native workflows across services.
For ecommerce brands that want organic connected to the rest of the growth engine - rather than SEO in a silo - Darkroom's integrated model ties search performance to customer lifetime value and profit. The tradeoff is that SEO is one line item among many, so ask exactly how many organic specialists sit on your account before you sign.
DTC brands describe Darkroom as a true full-funnel partner. Connecting organic to retention, creative, and marketplace revenue is the recurring reason scaling brands consolidate with them.
What clients sayWhy choose Darkroom:
- Integrated full-funnel model across every ecommerce discipline
- Search performance tied to LTV and profit
- AI-native workflows across services
Content-led organic growth and digital PR at enterprise scale
Siege Media is the content engine on this list. Founded by Ross Hudgens in 2012 and now around 110 people across Austin, San Diego, New York, and Chicago, they pair research-led content with digital PR and link acquisition for brands including Intuit, Asana, Zendesk, and Zillow. Recently they've reframed the whole offer around generative engine optimization, on the argument that the assets which earn links also earn AI citations.
For ecommerce, they're the right call when your category and product templates are already clean and the gap is authority: buying guides, comparison content, and the kind of linkable research that moves a competitive category. They're not a technical Shopify or Magento shop, and publicly reported minimums start in the $5,000 to $10,000 per month range, so check scope and fit before shortlisting them for a small catalog.
Clients credit Siege for content that earns links without a separate outreach vendor. The editorial standard and the custom design shipped with each asset are the recurring reasons brands renew.
What clients sayWhy choose Siege Media:
- Research-led content that reliably earns links in hard categories
- Digital PR and GEO run by the same team that writes the content
- Track record with recognizable mid-market and enterprise brands
SEO and link building with strong ecommerce authority work
Sure Oak is an SEO and link-building agency that combines technical SEO, content, and authority building, with solid experience growing ecommerce brands. Their link-building strength is a real asset in competitive product categories where authority gaps cap rankings.
They pair the off-page work with on-page and technical fundamentals, and they're known for a values-driven, communicative culture. They're a better fit once your templates are sound, since links won't rescue a category tree that Google can't crawl. For ecommerce brands in competitive niches that need authority alongside on-site SEO, Sure Oak is a well-regarded option.
Ecommerce clients credit Sure Oak for closing authority gaps that capped rankings. The link-building strength paired with solid on-site work is the recurring reason competitive brands choose them.
What clients sayWhy choose Sure Oak:
- Strong link building for competitive product categories
- On-page and technical fundamentals handled too
- Communicative, values-driven culture
Full-service ecommerce SEO at scale with revenue analytics
WebFX brings full-service scale to ecommerce SEO, backed by its MarketingCloudFX analytics platform that ties campaigns to revenue. For mid-market and larger stores that want SEO alongside PPC, content, and CRO with rigorous reporting, their breadth and review volume make them a dependable choice.
As a generalist with a large ecommerce practice, the smart move is to confirm your specific team's ecommerce-platform experience and ask who does the technical work. But for stores that want a single, well-resourced partner across channels with revenue-focused reporting, WebFX delivers capacity and discipline at scale.
Ecommerce clients credit WebFX for execution capacity and revenue-tied reporting. The analytics platform comes up constantly as the reason marketing activity stays connected to actual sales.
What clients sayWhy choose WebFX:
- Full-channel execution at scale with revenue analytics
- Strong reporting discipline and ROI focus
- Large verified review base
Accessible ecommerce SEO, PPC, and web for growing stores
SmartSites is a highly rated agency known for fast, conversion-focused ecommerce websites paired with disciplined SEO and PPC. For small and mid-sized stores that need a professional storefront plus dependable organic and paid growth without an enterprise budget, they're a pragmatic, accessible choice.
Strengths are value, speed, and a large body of work, with engagements commonly reported in the $1,500 to $5,000 per month range; the tradeoff is depth in advanced ecommerce SEO versus a pure specialist. For growing stores that want web, SEO, and paid handled competently by one team, SmartSites is a reliable default.
Growing stores praise SmartSites for clean ecommerce sites and dependable, well-priced SEO and PPC. The value and speed are the recurring reasons SMB merchants choose them.
What clients sayWhy choose SmartSites:
- Conversion-focused stores plus disciplined SEO and PPC
- Accessible pricing and fast turnarounds
- Large body of work across builds
What makes ecommerce SEO different from the rest of SEO
Three problems separate an online store from a normal website: filters that generate URLs faster than Google can crawl them, category pages that carry more revenue than any blog post will, and migrations that can erase a year of gains in a weekend. An agency that can't talk fluently about all three is a content agency with an ecommerce case study attached.
Faceted navigation is the biggest crawl problem you own
Do the arithmetic on your own filters. Take one category page with five filters and six options each. Every filter is either off or set to one of six values, which gives seven states per filter and 7^5 = 16,807 crawlable combinations from that single page. Run that across 40 categories and you have roughly 670,000 URLs competing for a crawl budget you sized for 8,000 products. That is why big catalogs go stale in the index while the merchant wonders why new products take six weeks to appear.
The fix is never to block everything. A handful of filter combinations have genuine search demand - color plus category, size plus category, brand plus category - and those deserve indexable pages with their own copy and internal links. Everything else should be canonicalized or noindexed, with links to junk combinations stripped so crawlers never discover them. Ask any agency you shortlist to show you the filter rules they wrote for a store your size, and how they decided which combinations earned a page. Vague answers here predict an expensive year.
Category pages carry the revenue, and most stores under-build them
"Womens waterproof hiking boots" is a category query. "Salomon Quest 4 GTX size 9" is a product query. The first has far more volume and is satisfied by a listing page; the second converts hard but only once the shopper already knows what they want. In the stores we audit, category and subcategory pages consistently drive the larger share of non-branded organic revenue, and they're almost always the thinnest templates on the site.
Good agencies treat a category page like a landing page: a short intro that answers the buying question, curated subcategories that match how people actually search, internal links from editorial content, and enough real detail that the page deserves to rank without 800 words of filler shoved under the product grid. If an agency's category plan is "add SEO text at the bottom," keep looking.
Migrations are where organic revenue quietly disappears
Replatforming, restructuring a category tree, or moving to headless all touch every URL you rank for. On a clean migration - complete redirect map, pre-launch staging crawl, parity checks on titles, schema, and internal links - expect a dip of roughly 10% to 20% for four to eight weeks. Get it wrong and 30% to 50% of organic revenue can vanish, with recovery measured in quarters rather than weeks. Put technical SEO in the migration budget before the build starts, not after the traffic drops.
Best ecommerce SEO agencies by platform
Platform fit decides more than agency reputation. A team that has untangled layered navigation on Adobe Commerce fifty times will do more for a Magento catalog than a better-known content shop, and the reverse holds when your templates are already clean and your problem is authority. Here is how the 17 above sort by stack.
Best for Shopify and Shopify Plus
Eastside Co and Netalico Commerce sit closest to the platform. Eastside Co builds and markets Shopify stores, so SEO gets designed into the theme instead of retrofitted around it. Netalico is the one to call for replatforms onto Shopify Plus and for the app and theme cleanup that quietly wrecks Core Web Vitals. Coalition Technologies covers Shopify well when you also need design and development capacity, and Searchbloom suits Shopify brands that want disciplined keyword prioritization without a build attached.
Shopify's constraints are consistent and worth naming in the first call: forced /collections/ and /products/ URL patterns, duplicate product URLs across collections, app scripts loading on every template, and limited server-side control over pagination. Any agency pitching you Shopify SEO should raise those before you do.
Best for Magento and Adobe Commerce
IWD Agency is the specialist pick, with Adobe-certified engineers doing the SEO work and more than fifteen years on the platform. 1Digital Agency is the strongest mid-market option, particularly for stores running Hyva front ends, and OuterBox handles large Magento catalogs where SEO, development, and CRO need to sit in the same room.
Adobe Commerce punishes neglect harder than anything else on this list. Layered navigation, default canonical and pagination behavior, multi-store view duplication, and heavy templates are all fixable, but only at the code level. If the agency you're considering can't read a Magento indexer config, they aren't doing Magento SEO - they're writing meta descriptions on top of a broken foundation.
Best for WooCommerce
WooCommerce stores are usually smaller and plugin-heavy, so the winning profile is a generalist with strong WordPress fundamentals rather than an ecommerce boutique. SmartSites and WebFX both fit growing Woo catalogs that want SEO, paid, and site work from one team. Victorious suits merchants who want organic only with a documented process, and Sure Oak is the one to add when your category has an authority gap rather than a technical one.
The recurring Woo problems are plugin conflicts, uncached filter queries that time out under load, and product attribute archives generating thin pages nobody asked for. That's WordPress SEO work as much as ecommerce work, so hire someone comfortable in both rather than a Shopify shop taking a detour.
Best for BigCommerce
1Digital Agency has the deepest BigCommerce bench of anyone here and holds platform certifications to match. OuterBox is the alternative for larger catalogs, and Coalition Technologies works when you need theme development alongside optimization. BigCommerce gives you more native SEO control than Shopify - editable URLs, built-in faceted search rules, sane 301 handling - which means BigCommerce SEO is less about workarounds and more about using the controls you already have properly.
What ecommerce SEO costs by catalog size
Catalog size is the fastest way to sanity-check a proposal. Here is what the market looked like at the time of writing. Treat these as ranges to negotiate from rather than quotes, and confirm current pricing with each agency directly.
Small catalogs, under roughly 500 SKUs, run $2,500 to $5,000 per month. At that budget you're buying one strategist, part of a writer, and a technical audit up front. SmartSites publicly reports engagements in the $1,500 to $5,000 range, which makes it one of the few credible entry points. Below about $2,000 a month you're usually buying a report rather than a program.
Mid-market catalogs, roughly 500 to 10,000 SKUs, run $5,000 to $15,000 per month. This is where category content, faceted-navigation work, digital PR, and CRO start running in parallel instead of taking turns. Coalition Technologies reports engagements around $2,500 to $7,500, OuterBox starts near $5,000, and content-led firms such as Siege Media report minimums closer to $10,000.
Enterprise catalogs, 10,000 SKUs and up or any multi-market store, run $15,000 to $50,000 and beyond per month - and at that scale SKU count stops being the driver. What actually costs money is the number of templates, storefronts, languages, and integrations. A 200,000-SKU parts catalog with four templates is cheaper to optimize than a 3,000-SKU brand selling in six markets. Budget it the way you'd budget enterprise SEO, and expect migrations to be quoted separately as fixed-scope projects in the $10,000 to $60,000 range.
Category changes the mix, not just the number. Fashion and beauty carry heavier content and digital PR costs because those SERPs are editorial. Industrial and parts catalogs carry heavier technical and data costs because the product data is messy. A fashion ecommerce program and a 90,000-part distributor program can cost the same each month and spend it on completely different work, which is why comparing two proposals on price alone tells you almost nothing.
Sanity check before you sign: divide the monthly retainer by your gross margin per order to get the extra orders the work has to produce just to break even, then divide that by your organic conversion rate to get the extra sessions needed each month. If that session number looks impossible for your category, the scope is wrong, not the agency.
What most stores get wrong when hiring an ecommerce SEO agency
Both sell ecommerce SEO services and they solve different problems, so the choice is less about budget than it looks.
A consultant sells diagnosis and direction. They audit the store, identify what is structurally wrong, build the roadmap, and hand it to your team or your developers to execute. It works well when you already have people who can implement, and it is usually the better value if your bottleneck is knowing what to do rather than having capacity to do it. It works badly when the roadmap lands on a developer queue and sits there for eight months, which happens more often than anyone plans for.
An ecommerce SEO agency sells diagnosis plus execution. Content gets written, technical fixes get specified and often implemented, links get built, and someone chases the developer queue on your behalf. You pay more because you are buying delivery capacity as well as thinking. The failure mode is different: agencies can stay busy producing output that is not the highest-leverage work, particularly when the highest-leverage work is a platform change nobody wants to sign off.
The practical test is what happened to your last SEO audit. If you have one and nothing in it got built, hiring another consultant to write a better one will not change the outcome. If you have never had a proper technical audit of the catalogue, starting with a consultant is often the cheaper path to knowing whether you need an agency at all.
What ecommerce SEO services cost
Pricing in this category tracks catalogue size and technical debt far more than it tracks agency prestige, which is why quotes for the same brief can differ by a factor of four.
The variables that actually move a quote are the number of indexable URLs, whether the platform can be changed or only worked around, whether product content is written in house or by the agency, and whether the agency is expected to implement technical fixes or only specify them. A store with two hundred SKUs on a clean Shopify build is a fundamentally different engagement from a fifty thousand SKU Magento install with eight years of accumulated redirects.
Typical ecommerce SEO pricing by store size
Typical ecommerce SEO pricing by store size
| Store profile | Common engagement shape | What is usually included |
|---|---|---|
| Under 500 SKUs, single market | Monthly retainer at the lower band, or a fixed-scope project | Technical audit, category page work, product content templates |
| 500 to 5,000 SKUs | Monthly retainer with a defined content and link allocation | The above plus ongoing content, internal linking systems, link acquisition |
| 5,000 to 50,000 SKUs | Larger retainer, often with a separate technical implementation scope | Faceted navigation strategy, crawl budget management, feed and schema work |
| 50,000+ SKUs or multi-market | Enterprise retainer, frequently with a dedicated technical resource | All of the above plus international structure, log file analysis, platform migration support |
| Migration or replatform | Fixed-scope project priced separately from any retainer | Redirect mapping, pre-launch QA, post-launch monitoring |
Two things are worth insisting on regardless of band. First, that the agency reports on organic revenue rather than sessions, because ecommerce traffic that does not convert is easy to manufacture. Second, that any migration work is scoped and priced separately from ongoing retainer work. Migrations are where catalogues lose the most visibility fastest, and burying them inside a general retainer means nobody is properly accountable for the outcome. Start with an SEO audit if you need a baseline before you commit.
What most stores get wrong when hiring an ecommerce SEO agency
3. Buying content when the problem is architecture
Blog volume is the easiest thing for an agency to sell and the easiest thing to measure, which is why it gets proposed for problems it can't solve. If your category pages aren't indexed, your filters are eating crawl budget, and your templates fail Core Web Vitals, forty articles will not move revenue. Fix the foundation, then buy content.
2. Letting the developer queue set the pace
The most common reason ecommerce SEO stalls is not bad recommendations, it is recommendations that never get built. Technical fixes compete with feature work and lose, quarter after quarter, until the retainer gets cancelled for underperforming. Before you sign, agree who implements what. An agency with direct platform access moves faster than one filing tickets, and if yours cannot have access, budget developer time explicitly rather than assuming it will appear.
3. Judging performance on rankings instead of revenue
Ranking reports are easy to make look good. Pick the right keyword set and almost any account improves on paper. Organic revenue, organic new customers and organic revenue per session are harder to game and are the only numbers that answer whether the engagement is working. Insist on those in the monthly report from month one, and insist on a baseline being recorded before work starts.
4. Treating a replatform as a project the agency can absorb
Migrations are the single highest-risk event in ecommerce SEO and stores routinely announce them to their agency a few weeks out, inside an existing retainer, with no additional scope. Redirect mapping across a large catalogue is substantial work and doing it badly costs visibility that takes a year to recover. Scope migrations separately, start them early, and have the agency involved before the new templates are built rather than after.
How ecommerce SEO is changing in 2026
Agentic commerce is moving from demo to roadmap. Shopping agents read structured product data, availability, and pricing directly, which rewards stores whose feeds and schema agree with each other and punishes stores where they don't.
Technical foundations matter more, not less. Core Web Vitals, crawl efficiency, and clean faceted navigation are prerequisites for both Google and AI engines to trust and surface your catalog.
The second shift is that thin category pages are being penalised harder than thin product pages. Search results for commercial category terms increasingly favour pages that demonstrate genuine selection knowledge: buying guidance, comparison, filtering logic explained in copy rather than only in a sidebar. The old pattern of a category page with a headline, a paragraph of keyword-padded copy and a product grid is losing to pages that behave like a curated shortlist.
If you do one thing this quarter, audit your top twenty category pages for word count and buying guidance. On most stores they are the highest-intent and lowest-effort pages on the site, and that gap is the cheapest ranking opportunity available.
When you evaluate an ecommerce SEO company, ask how they handle product data quality and category page depth specifically. Those two answers separate agencies working from a current playbook from agencies still running one built for 2019. For AI-led discovery specifically, see our AI SEO agency page.

Most ecommerce SEO engagements run $3,000 to $15,000 per month, with large catalogs and competitive niches reaching $15,000 to $50,000 and beyond. Smaller stores can find capable help from $2,500 to $5,000, and SmartSites publicly reports work in the $1,500 to $5,000 range. Content-led firms such as Siege Media report minimums closer to $10,000. Migrations and technical projects are usually scoped separately as fixed-fee work, often $10,000 to $60,000. The cheapest option is rarely the most cost-effective once lost rankings and wasted retainers are counted. Verify current pricing on each vendor's site before you budget.
Hire for the platform you actually run, because the failure modes are different. Shopify problems are usually app bloat, forced URL patterns, duplicate product URLs across collections, and limited server-side control, so a Shopify SEO team like Eastside Co or Netalico Commerce earns its fee fast. Adobe Commerce problems are layered navigation, indexer configuration, multi-store duplication, and heavy templates, which need engineers, not editors - IWD Agency and 1Digital Agency fit there. A generalist can succeed on either, but you pay for their learning curve on your store, and platform mistakes are the expensive kind.
Ecommerce SEO has unique problems - faceted navigation, crawl budget on huge catalogs, PDP and PLP templates, product schema, and feed alignment - that generalists routinely mishandle. A specialist understands these at the template level and knows your platform's quirks, which is the difference between scaling organic revenue and a botched migration.
Expect early movement in three to four months and meaningful organic revenue gains in six to nine, longer for new domains or crowded categories. Technical fixes produce the fastest wins: indexation and Core Web Vitals work can show up within weeks because you're releasing traffic that was already blocked. Category content and authority compound over quarters. If you're recovering from a bad migration, budget two quarters rather than two months. Be sceptical of anyone promising a sales flood in the first few weeks, and ask what they expect to change in month one versus month six.
Only up to a point. SKU count is a rough proxy for pricing at the small and mid-market end: under 500 SKUs usually means $2,500 to $5,000 per month, and 500 to 10,000 SKUs usually means $5,000 to $15,000. Past that, the real cost drivers are the number of templates, storefronts, languages, and integrations. A 200,000-SKU parts catalog running four templates is cheaper to optimize than a 3,000-SKU brand selling across six markets in four languages. When you get a quote, ask which of those variables the agency priced against, not how many products they counted.
Bring SEO in before the build starts, not the week of launch. The non-negotiables are a complete URL inventory from crawl plus log files plus Search Console, a one-to-one redirect map with no chains, a staging crawl that checks titles, canonicals, schema, and internal links against the old site, and a prioritized list of your top revenue URLs to verify manually after go-live. Even a clean migration typically dips 10% to 20% for four to eight weeks. A bad one costs 30% to 50% and takes quarters to recover. Agencies with real migration track records include OuterBox, Netalico Commerce, and NOVOS.
The best ones do, and it's now a fair filter for a shortlist. As product discovery moves into AI Overviews and shopping assistants, structured data, schema graphs, consistent feeds, and answer-ready content decide whether your products get surfaced or skipped. Ask any agency how they approach AEO, GEO, and agentic commerce, and what they'd change on your product templates specifically. Many still treat it as an add-on line item. Siege Media has rebuilt its offer around generative engine optimization, Netalico publishes on agentic commerce, and 1Digital ships GEO work alongside classic technical SEO.
Both, in sequence, and the order depends on your bottleneck. If you already have organic traffic but conversion sits below your category benchmark, CRO produces faster revenue than more rankings - that's when a specialist like The Good pays for itself. If organic visibility is low, no amount of testing helps because you don't have enough traffic to test against; fix indexation, templates, and category coverage first. The strongest agencies do both, or coordinate with a CRO partner, so traffic gains turn into orders instead of bounces.
Month one should produce a technical audit tied to revenue, not a 200-point checklist: indexation status by template, faceted-navigation rules, Core Web Vitals by page type, and a ranked list of category opportunities with estimated revenue attached. Month two should be shipping fixes, not writing more documents. By month three you should see indexation and crawl metrics moving, the first category templates rebuilt, and a reporting view that shows organic revenue by category rather than aggregate sessions. If 90 days have passed and nothing has shipped to production, that's your signal to renegotiate or leave.
