How the Calculator Works

Traffic modeling

We use position-specific CTR data from Google Search Console industry benchmarks across thousands of keywords to estimate how much traffic your target ranking position will deliver.

Revenue calculation

Revenue projections account for your business type — SaaS, eCommerce, B2B services — because visitor-to-lead-to-customer funnels differ materially by industry.

GEO uplift

Unlike other calculators, we include an optional AI search visibility multiplier. As ChatGPT, Perplexity, and Gemini drive more discovery, brands optimized for SEO and GEO can see 15–35% additional reach.

Frequently asked questions

How do you calculate SEO ROI?

We estimate future organic sessions from your current traffic and ranking positions using CTR benchmarks by position, apply your conversion and deal assumptions (with optional two-step funnel), layer an optional GEO multiplier for AI-driven discovery, and compare cumulative ramped revenue to your monthly SEO spend.

What is a good ROI for SEO?

Healthy programs often land in the hundreds of percent over 12 months once rankings compound, but it varies widely by industry, competition, and starting authority. Use benchmarks as directional context, not guarantees.

How long does SEO take to show ROI?

Most teams see directional gains in 3–6 months and compounding impact over 6–12 months. Our model uses a ramp curve so revenue does not jump to full value in month one.

What is the average cost of SEO per month?

Agency retainers commonly range from a few thousand to tens of thousands per month depending on scope, content velocity, and technical depth. Align spend with realistic timelines and competitive intensity.

Is SEO better ROI than Google Ads?

Often yes over a 12–24 month horizon because organic equity compounds while paid stops when spend stops — but paid can win short-term. We show an Ads-equivalent value to contextualize efficiency.

How does AI search affect SEO ROI?

AI surfaces synthesize trusted sources; brands with strong topical authority can earn incremental discovery. Our optional GEO multiplier approximates that uplift; pair it with traditional SEO for full coverage.

What is the difference between SEO ROI and organic traffic value?

Traffic value estimates what clicks would cost in ads. SEO ROI compares modeled revenue against your actual SEO investment — a business outcome lens, not just media equivalency.

How accurate is an SEO ROI calculator?

Any model is directional. Accuracy improves when you use real Search Console positions, Analytics sessions, and honest conversion data. Treat outputs as planning inputs, not financial promises. technical SEO audit.
