Start with crawlability and indexation checks (robots.txt, XML sitemap, canonicals), then review technical foundations like Core Web Vitals and HTTPS, followed by on-page elements such as title tags, meta descriptions, and headings. Finish with content quality and E-E-A-T assessment, then organize findings into a prioritized action plan.

Traffic drops after migration usually come from missing or broken 301 redirects, incorrect canonical tags, blocked crawlers in robots.txt, or outdated XML sitemaps. Check Search Console coverage reports for indexation errors and verify redirect mapping from old URLs to new ones.

No. Many CMS plugins inject JSON-LD via client-side JavaScript, which web_fetch and curl cannot see because script tags are stripped or never executed. Use a browser rendering tool, Google Rich Results Test, or a Screaming Frog export to accurately detect structured data.

Largest Contentful Paint should be under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, and Cumulative Layout Shift under 0.1. Pages loading in 5-6 seconds are well above acceptable limits and page speed is a confirmed ranking factor.

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 schema skill when the task is implementing structured data such as FAQ or product markup on pages. An SEO audit diagnoses issues and prioritizes fixes, while schema implementation is a separate build task.
