An SEO audit is the foundation of any effective organic strategy. Without a clear diagnosis of your current technical health, content gaps, and authority position, it is impossible to know where to direct investment. Here is the exact process we use to identify what is holding a website back — and how we prioritise what to fix first.
Phase 1: Technical health audit
The technical audit covers the infrastructure that search engines use to discover, render, and evaluate your content. Technical issues can silently suppress rankings for months or years before anyone identifies them. Start with a full site crawl using a tool like Screaming Frog, Semrush, or Ahrefs Site Audit.
Crawlability and indexation
- Are all priority pages indexable? (Check robots.txt and noindex tags)
- Is your XML sitemap up-to-date and correctly structured?
- Are there significant numbers of 4xx errors on crawled pages?
- Are there redirect chains longer than 2 hops?
- Does Google Search Console show indexation errors or excluded pages?
Core Web Vitals and page speed
Core Web Vitals — Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) — are page experience signals that influence rankings, particularly in competitive markets. Run your site through PageSpeed Insights and Google Search Console's Core Web Vitals report to identify pages with poor scores. LCP under 2.5 seconds and CLS under 0.1 are the targets.
Phase 2: On-page and content audit
Content audits evaluate whether your existing content is optimised for its target keywords, whether it meets the search intent of users finding it, and whether it demonstrates the expertise, authoritativeness, and trustworthiness (E-E-A-T) that Google increasingly uses to evaluate content quality.
- Does each priority page have a unique, descriptive title tag including the primary keyword?
- Are meta descriptions compelling and within length limits?
- Does the content adequately cover the topic relative to top-ranking competitors?
- Is there keyword cannibalisation — multiple pages competing for the same terms?
- Are internal links used to connect related content and pass authority?
- Is structured data (schema markup) implemented where appropriate?
Phase 3: Backlink and authority audit
Your backlink profile is one of the strongest determinants of your ability to rank for competitive keywords. An authority audit examines the quality and quantity of links pointing to your domain, identifies any toxic or unnatural links that could be suppressing performance, and maps your authority position relative to key competitors.
What to look for in a backlink audit
- Total referring domains vs. competitors for priority keywords
- Distribution of link authority (DR/DA spread)
- Presence of toxic or unnatural-looking links
- Anchor text distribution (over-optimised exact-match anchors are a risk signal)
- Lost links — high-authority links that have been removed in the past 6–12 months
Phase 4: Competitive gap analysis
Understanding what your competitors are doing — and where they have advantages — is as important as understanding your own site. A competitive gap analysis identifies keyword opportunities where competitors rank but you do not, content topics they have covered that you have not, and authority differences that explain ranking disparities.
The most valuable output of an SEO audit is not a list of every issue — it is a prioritised roadmap. Every issue should be scored by impact (how much will fixing this improve rankings?) and effort (how difficult and time-consuming is this to fix?). High-impact, low-effort fixes come first.
How to prioritise audit findings
A thorough SEO audit for a medium-to-large site typically uncovers 50–150 distinct issues. Trying to fix everything simultaneously is neither practical nor strategic. Prioritise by: (1) Revenue impact — which issues, if fixed, would most directly drive qualified traffic to pages with commercial intent? (2) Implementation effort — how quickly and easily can this be resolved with available resources? (3) Risk — are there any issues actively suppressing your rankings that need immediate attention regardless of fix difficulty?
