seo-audit

Start with crawlability and indexation (robots.txt, XML sitemap, canonical tags), then check technical foundations like Core Web Vitals and HTTPS, followed by on-page elements and content quality. The audit produces findings with impact ratings and a prioritized action plan.

Common causes include missing 301 redirects from old URLs, incorrect canonical tags, blocked crawlers in robots.txt, and outdated XML sitemaps. Check the Search Console coverage report for indexation errors and expect recovery to take weeks after fixes.

No. Many CMS plugins inject JSON-LD via client-side JavaScript, which web_fetch and curl cannot see because script tags are stripped. Use a browser rendering tool, Google Rich Results Test, or a Screaming Frog export instead.

LCP (Largest Contentful Paint) should be under 2.5 seconds, INP (Interaction to Next Paint) under 200ms, and CLS (Cumulative Layout Shift) under 0.1. Measure them with PageSpeed Insights, WebPageTest, or the Search Console Core Web Vitals report.

The most common errors are missing self-referencing entries, non-reciprocal links between locale pages, invalid codes like en-UK instead of en-GB, and canonical URLs that conflict with the hreflang set. Any of these can cause Google to ignore the annotations entirely.

Use a dedicated schema skill when the task is implementing structured data such as FAQ or product markup. An SEO audit diagnoses issues and verifies existing markup, but implementation of new structured data is a separate task.
