The starting point

A free, comprehensive and actionable SEO audit

The Atelier analyses your website across more than 90 checks, shows the affected pages and turns findings into priorities. Your workspace can then connect competitors, AI visibility and Google data.

Short answer

What a free SEO audit on Atelier SEO contains

The audit runs your website through more than 90 checks. They fall into four families: crawlability and indexing, on-page and structured data, performance and experience, priorities and evidence. It returns problems ranked by impact, each tied to the affected URLs and to an action. It is written for the owner who has to decide what to fix first.

What is actually checked

A page-by-page diagnostic, not an isolated score

Each family answers a precise question and keeps the evidence needed to verify the finding.

Crawlability & indexing

Robots, sitemaps, HTTP status, canonicals, depth and the pages Google can actually discover.

On-page & structured data

Titles, descriptions, hierarchy, content, internal links and Schema.org markup.

Performance & experience

Core Web Vitals, resource weight, images, visual stability and issues observed across templates.

Priorities & evidence

Severity, affected URLs, risk explanation and a correction order instead of a raw problem list.

The checks in detail

What each family of checks actually contains

The points below are verified by the audit on your own website. They show the level of detail returned, not a result announced in advance.

Crawlability and indexing: what is verified

The audit reads your robots.txt, your sitemap and the response returned by every address it visits.

  • Whether robots.txt lets search engines crawl the pages that actually matter.
  • The sitemap exists, is declared in robots.txt, and its addresses still respond.
  • Service pages such as cart, internal search or filters do not take the place of useful pages.
  • Canonical tags and click depth tell the same story as your site structure.

What a detected problem reveals

A blockage here does not cost positions. It costs indexing: the page never enters the race.

On-page and structured data: what is verified

The audit compares the title shown in Google, the title visible on the page and the subject actually covered.

  • Every page carries a unique H1 that states what it is about.
  • No two pages share the same title tag, otherwise they compete for the same search.
  • The title fits the width Google displays, without being cut mid-word.
  • Images carry alternative text, and Schema.org markup describes what the page contains.

What a detected problem reveals

A duplicated or truncated title shows up in the click-through rate before it shows up in the position.

Performance and experience: what is verified

The audit measures the real weight of your pages, then compares that measurement with your visitors' own when Google provides it.

  • Images are served in a modern format, at the right weight and the right dimensions.
  • Dimensions are declared, otherwise the text jumps while the page loads.
  • Off-screen images wait their turn instead of delaying the first render.
  • Core Web Vitals recorded on your real visitors are compared with Google's thresholds.

What a detected problem reveals

A slow page does not only lose rankings. It loses the visitor before being read at all.

How a problem becomes a ranked priority

A finding never arrives alone. It comes with its severity, the affected addresses and the order in which to handle it.

  • Severity comes from the observed effect on indexing, clicks or speed.
  • Every problem names the URLs concerned, so you know where to act.
  • Every check explains what it is for and what its failure changes, in plain language, with no bare error code.
  • The score is recalculated on every new audit: the correction is what moves it.

What a detected problem reveals

A list of problems is read in an hour. A correction order is put to work the next day.

Decide before you build

Should your website be fixed or rebuilt?

The audit should not confirm a decision that has already been made. It uses verifiable evidence to choose between targeted corrections and a redesign.

Fix

The foundation is sound and the losses are contained

A focused correction is enough when the CMS remains usable, the structure still represents the offer, and the problems are concentrated in a few templates or pages.

  • Strategic URLs are stable and already known to Google.
  • Useful content can be improved without replacing the whole navigation.
  • Technical issues have an identifiable and limited cause.

Redesign

The website prevents the offer and content from evolving

A redesign becomes rational when every improvement needs a workaround, templates block clear information, or the architecture no longer represents the business.

  • The CMS no longer supports reliable publishing or measurement.
  • Pages compete because the information architecture has lost its logic.
  • The conversion path cannot be simplified without rebuilding templates.

The threshold

The threshold beyond which fixing is no longer enough

Three criteria can be observed without technical expertise. Place your website on each row, then look at the column that comes back most often.

Observable criterionFixThe foundation still holdsTipping zoneBoth cases stand upRebuildThe website is the ceiling
Major technical blockersOne or two, on identified templates.Three to five, each one still workable around.
Age of the technical foundationUnder three years, the CMS still keeps up.Three to six years, every update takes time.
Ability to carry a new offerA new page ships without a developer.A developer is needed, not a rebuild.
What the audit shows month after monthCorrections hold once they are applied.Corrections hold, but the list never gets shorter.

Two rows out of three on the same side are enough to decide. When the right-hand column wins, the formula with a redesign included becomes the logical next step rather than a run of corrections.

If a redesign is recommended, the plan must list the URLs to keep, merge or redirect. Otherwise the redesign remains a visual project with no SEO safety net.

To go further: compare the three formulas, see how a redesign unfolds, prepare the SEO migration URL by URL, the 12 points to check before rebuilding a website, choose between in-house work, an agency and a rebuild.
