What an SEO audit actually looks like

What is an SEO audit (and what isn't one)?

It isn't an automatic list generated by a tool in 2 minutes. A serious audit covers five areas: technical health, on-page, user experience, content quality, and, more recently, AI visibility. An audit that only looks at rankings in Google's blue links ignores a growing share of real traffic.

Why run an SEO audit before any content strategy?

Critical technical problems are more common than people think. A single noindex tag forgotten on a high-value page can wipe out thousands of monthly visits without triggering any visible alert. The audit exists precisely to detect this kind of problem before it costs traffic for weeks.

How does an SEO audit work? The 5 steps

1. Accessibility and indexing: robots.txt, sitemap, indexing status of each page (Search Console indexing report).
2. Technical performance: Core Web Vitals measured on real-world data (CrUX), not only lab simulation.
3. Structure and internal linking: spotting orphan pages, meaning pages with no incoming internal link.
4. Content and search intent: each page is checked against the queries it's meant to target.
5. Accessibility for AI crawlers: GPTBot, ClaudeBot and PerplexityBot crawl the web with their own rules, described by OpenAI, Anthropic and Perplexity; an audit that only checks Googlebot is incomplete.

What does an SEO audit concretely change for a website?

An audit doesn't produce traffic by itself: it saves time by identifying, in order, the blockers that cost the most (indexing, speed, duplicate content, internal links). Google says so in its documentation: basic SEO best practices remain the foundation, including for the AI features in Search (Google Search Central).

What deliverables to expect from an SEO audit? (a prioritised report)

A prioritised report (not a raw list of 200 problems), ranked by impact and ease of fix, with for each item: the problem, its evidence (screenshot, data), and the precise corrective action.

What are the blind spots of an incomplete SEO audit?

Technical, on-page and off-page: why not to separate them

A technical audit is only one part of SEO, alongside on-page (content and tags) and off-page (links). Google describes these fundamentals in its SEO starter guide. It's exactly the logic I apply: an audit that only looks at the technical side without putting it in perspective with content and links gives an incomplete, even misleading, picture of a site's real state.

What an audit ignoring AI crawlers costs (GPTBot, ClaudeBot, PerplexityBot)

An audit that only covers Googlebot leaves an ever wider blind spot: GPTBot, ClaudeBot and PerplexityBot now crawl the web with their own access rules. On the hotel projects I've handled, ignoring this blind spot has already cost measurable visibility in AI answers before the client even noticed — because nothing in classic rank-tracking tools warns about this kind of loss.

How to document an SEO audit and how often to repeat it?

Dated screenshots: the proof of every issue identified

Every audit I deliver includes a dated screenshot for each problem identified, not just a written description. That's what makes it possible, six months later, to objectively measure whether the fix had the expected effect — and to avoid endless debates about what was actually seen at the time of the audit.

How often should you redo an SEO audit? (yearly, quarterly, hotel seasonality)

An audit is never a one-off event. I recommend a full audit at least once a year, and a lighter technical check every quarter for high-traffic or fast-changing sites (regular page additions, CMS changes, migrations). On hotel projects, seasonality also changes the picture: an audit carried out just before high season doesn't have the same urgency to fix things as one carried out in a quiet period, when heavier fixes can be made without risking disruption to a booking peak. In both cases, the timing of the audit matters as much as its content.
