# The complete SEO audit checklist for 2026

The 42 points to check on an existing site to identify what's holding back its search rankings.

In this guide

[Technical audit](#technique) [Editorial audit](#contenu) [Authority audit](#autorite) [GEO and AI rankings](#geo)

## Technical audit

Indexability, Core Web Vitals performance, URL structure, Hn markup, structured data, sitemap, robots, redirects, mobile version, accessibility.

A poorly indexed site will never rank, no matter the quality of its content.

## Editorial audit

Depth of key pages, coverage of search intents, cannibalization between pages, actual perceived quality, freshness, internal linking.

## Authority audit

Backlink profile, brand mentions, local signals, presence in industry media.

## GEO and AI rankings

Presence on ChatGPT, Perplexity, Gemini: citations, sources reused, extract quality. SEO alone is no longer enough, you now need to think GEO in parallel.

## Questions & answers

01 Can a site with great content but poor indexing rank well?

No. An indexability problem blocks everything, regardless of editorial quality. That's why the technical audit always comes before the content audit.

02 Does GEO replace the classic SEO audit?

No, it's added as a fourth block. We always audit technical, editorial and authority before assessing presence in AI answers.
