What the SEO audit skill does

The assistant can examine a website for issues like robots.txt blocking, sitemap references, page titles, Core Web Vitals, multilingual setup, and E-E-A-T signals. It then builds a prioritized action plan, beginning with fixes that prevent indexing or ranking. It applies whenever someone wants to examine, assess, or troubleshoot SEO problems on their site.

What it covers

Crawlability and indexation checks (robots.txt, sitemaps, canonicals)
Site speed and Core Web Vitals review
International SEO and hreflang checks for multilingual sites
Prioritized audit report with action plan
