What a website audit covers in 2026

Your prospects search on Google and also ask ChatGPT, Perplexity or Gemini. The audit looks at your site the way search engines, AI assistants and visitors see it: 30 checkpoints, six areas.

  • Technical: what Google can crawl and index

    A page crawlers cannot reach will never rank. Every strategic page must be crawlable, indexed, fast and secure.

    • Crawl depth and crawl budget
    • Indexing, canonical tags and XML sitemap
    • Core Web Vitals: LCP, INP, CLS
    • Mobile rendering and usability
    • HTTPS, redirects and 404 errors
  • On-page SEO and semantics

    Which page answers which of your prospects’ searches, which pages compete with each other, which ones are missing.

    • Search intent of each page
    • Keyword cannibalization
    • Title tags, meta descriptions and headings
    • Internal linking and orphan pages
    • Keywords your competitors capture
  • Content and E-E-A-T

    Google and AI engines alike favor content that proves real experience. We assess its quality, freshness and credibility.

    • Thin, duplicate or outdated pages
    • Named authors and visible expertise
    • Proof: sourced figures, case studies, reviews
    • Freshness of key content
    • Topics buyers expect and cannot find
  • Visibility in AI search (GEO)

    Is your brand cited when people ask AI assistants about your field? Does your site give them enough to cite you?

    • Structured data (schema.org)
    • llms.txt file and AI crawler access
    • Bing indexing, used by ChatGPT and Copilot
    • Citations in ChatGPT, Perplexity and Gemini
    • Presence in Google AI Overviews
  • Authority and link building

    Links and mentions from other sites weigh on your rankings and on how often AI engines cite you. We benchmark your profile against your competitors.

    • Referring domains and their quality
    • Toxic or artificial links
    • Anchor text and linked pages
    • Brand mentions in the media
    • Authority gap with competitors
  • Conversion and user journey

    We follow a visitor’s path to your forms and check that every conversion is properly measured.

    • Landing pages and calls to action
    • Forms: length, errors, confirmation
    • Mobile path to conversion
    • GA4 and Google Tag Manager tracking
    • Lead source tracking and cookie consent
When to audit

Warning signs that call for an audit

Any one of these situations is enough to justify a diagnosis.

  • Organic traffic is falling

    Clicks in Search Console have been falling for weeks. A Google update, a competitor or a technical fault: the audit tells you which.

  • A redesign or migration is coming

    New CMS, domain or site structure: without a baseline and a redirect plan, part of your traffic disappears at launch.

  • Rankings are stuck on page two

    Your key pages plateau between positions 11 and 30, most often because of cannibalization, thin content or weak authority.

  • Some pages never get indexed

    Search Console has flagged them as “Crawled, currently not indexed” for months. Google either cannot reach them or does not find them useful.

  • Leads arrive with no known source

    Requests come in, but nobody knows whether they came from Google, a campaign or an article. Budget decisions become guesswork.

  • AI answers leave your brand out

    Asked about your field, ChatGPT or Perplexity cite your competitors. The causes lie on your site and beyond it.

Audit or SEO retainer?

Website audit or SEO support: what is the difference?

The audit is a one-off diagnosis. SEO support puts it to work over time. You can order one without the other.

  • The website audit

    A one-off diagnosis

    A full snapshot of your site at a given moment. It answers one question: what is holding back your visibility and leads, and where should you start?

    • Scope set at kickoff
    • Report and roadmap
    • Implemented by you or with us
  • SEO and GEO support

    Execution over time

    Monthly work over three months minimum: technical fixes, content, link building, rank tracking. It is described on our SEO & GEO agency page.

    • Full audit included from our entry SEO plan
    • Content and backlinks every month
    • Live dashboard
Method

How a website audit works

Five steps, from the first call to implementation. The timeline depends on the size of your site.

  • 01

    Scoping and access

    One call sets the goals, the scope (pages, languages, markets) and the competitors to benchmark. You give us read-only access to Search Console, GA4 and Tag Manager.

  • 02

    Crawl and data collection

    We crawl the site page by page, as Google does, and cross-check the crawl with 16 months of Search Console and GA4 data. Then we ask AI assistants your customers’ questions.

  • 03

    Analysis and prioritization

    Each issue becomes a recommendation scored on its impact and on the effort it takes. Quick, high-impact fixes go to the top.

  • 04

    Findings and costed action plan

    We present the findings in a workshop to your marketing and technical teams. Each action is costed in days of work and given an owner: you, your web agency or us.

  • 05

    Implementation support

    We stay available while your teams make the fixes: questions, trade-offs, checks on what goes live, a 90-day checkpoint. Or we take over through SEO support.

Tools we use

  • Google Search Console
  • Google Analytics 4
  • Google Tag Manager
  • Screaming Frog
  • PageSpeed Insights
  • Semrush
  • Ahrefs
  • Looker Studio
Deliverables

What you receive at the end of the audit

Documents you can use the next day, without needless jargon.

  • A prioritized audit report

    Findings across the six areas, each with its evidence (screenshot, data, URL), its severity and its fix. Summary first, details in the appendix.

  • A 90-day roadmap

    Actions ranked by priority over three months, with the estimated effort and owner of each, in a spreadsheet ready to import.

  • A findings workshop

    A session with your teams, on site or by video call, to present the results, answer questions and agree on the order of work.

  • Metrics tracking

    A Looker Studio dashboard connected to Search Console and GA4: rankings, clicks, indexed pages, conversions.

Frequently asked questions

Website audit FAQ

Answers to the questions we hear before an audit starts.

What is a website audit?

A complete diagnosis of a website at a given moment. It identifies what is holding back visibility and conversions (technical, SEO, content, authority, AI search visibility, conversion) and ends with an action plan ranked by impact and effort.

How much does a website audit cost?

The audit is part of our SEO support, from €1,800 excluding VAT per month (Foundations plan): our prices are public on the pricing page. The scope (site size, languages, areas covered) is agreed before we start.

See our pricing

How long does a website audit take?

Usually one week of analysis once access is granted, followed by the findings workshop. A large, multilingual or e-commerce site takes longer: the timeline is set at kickoff.

SEO audit or website audit: what is the difference?

An SEO audit covers ranking in Google: technical health, content, links. Our website audit includes it and adds AI search visibility and conversion (tracking, forms, landing pages). It is the right fit if your goal is leads and not only rankings.

Should I audit my site before a redesign?

Yes, ideally two to three months before. The audit lists the pages that bring in traffic and links, the basis of the redirect plan, and keeps the old site’s flaws out of the new one. A check right after launch confirms redirects and indexing.

Does the audit cover visibility in ChatGPT and other AI tools?

Yes. We ask ChatGPT, Perplexity, Gemini and Google AI Overviews your customers’ questions and record who gets cited. On your site, we check structured data, llms.txt, AI crawler access and Bing indexing. The sources these tools cite become targets for link building and media relations.

What happens after the audit?

Start with the quick wins at the top of the roadmap, then schedule the heavier projects. Your team can handle them alone, with our review, or hand the rest to us through SEO support. A 90-day checkpoint measures the effect.
