Who it is for

  • You rebuilt the website and nobody has measured it since
  • Your website is slow on mobile or fails Core Web Vitals
  • You want to know whether AI assistants can read what you sell

You don't need it if your website is a placeholder page with no commercial goal. And if all you want is one page's score, PageSpeed gives it to you without us.

A website nobody finds doesn't sell

The home page looks impressive on the laptop of whoever built it. On a phone, in another language or to a search engine, the same website has flaws nobody sees: pages that only exist with JavaScript, text that cannot be read against its background and AI crawlers blocked without anyone knowing. Our two own websites, reviewed with this method, score 100 in SEO on PageSpeed.

What the website audit and SEO audit covers

  • Performance and Core Web Vitals, on mobile and desktop
  • SEO and indexing: what Google can read and what it can't
  • Visibility in AI assistants (GEO and AEO)
  • Accessibility and contrast (WCAG 2.2 AA)
  • Security and headers
  • Copy, languages and hreflang
  • Links, buttons and forms

More than 275 control points

How it works

  1. Meeting and written scope

    In 30 minutes we look at your website, its main pages and what you want it to achieve. Then you get the scope and timeline in writing.

  2. Measurement on the real page

    We measure the website as a visitor, a search engine and an AI assistant receive it, on mobile and desktop. Each issue is checked before it goes into the report.

  3. Report and results meeting

    You get the PageSpeed report with what lowers each score and the list of issues by impact. We go through it with you and with whoever runs the website.

What we need from you

  • Your website's address and its most important pages
  • A test account, if there is a logged-in area
  • A contact person: your team or your agency

How we work

What you get

  1. PageSpeed report: what lowers each of your website's scores
  2. List of issues, ranked by impact
  3. Technical report: the evidence and the priority of each finding
  4. One-page executive summary for leadership

How a finding arrives

Priority: High

Service pages that only exist with JavaScript

Where
Product pages, mobile version
Evidence
Without JavaScript the page arrives empty, and the AI crawler receives the same empty HTML
Impact
Neither Google nor AI assistants can read what you sell

Expert review, automated tool or the AI itself

All three are useful, each for one thing. AI brings the volume and people bring the judgment: that is why our review uses an automated AI tool and senior developers supervise it.

Who reviews

The review is done by a team of senior developers, with many hours of development and of finding the mistakes AI makes when it codes. We know more than 1,200 review points. The automated AI tool goes through them, and people verify, direct and review.

Frequently asked questions

What is an SEO audit and what should it include?

It is a review of what keeps a search engine from reading, understanding and showing your website. It should include indexing, content, internal links, structured data and performance. Our health check adds how AI assistants read the site, accessibility and security.

What is PageSpeed Insights used for, and what does this review add?

PageSpeed Insights measures the performance of one page, and its report goes inside ours. We also measure, across the whole site, whether Google and AI assistants can read your website, plus languages, links, contrast and security headers.

What is the difference between GEO and SEO, and how do you rank in ChatGPT?

SEO prepares your website for search engines and GEO prepares it for AI assistants such as ChatGPT or Perplexity. Whether a model cites you is not in anyone's hands, and we don't promise it. What we review is that AI can reach your website, read it and find something to cite you with.

How much does an SEO audit or a website audit cost?

The 30-minute meeting is free. The rest depends on the size of your website: how many pages and languages it has and whether there is a logged-in area. We go over it in that meeting, and you get the scope and timeline of our health check in writing before we start.

Do you fix what you find on the website?

The diagnosis comes first, with the list of issues and their evidence. The fix is separate and only if you ask: your team or your agency applies it, or we do if you ask us to.

How do you do an SEO audit, and what do you need to get started?

You measure the live website as a visitor receives it and as a search engine reads it, page by page. For our health check we need your website's address, its most important pages and, if there is a logged-in area, a test account.
