The Full Guide

Technical SEO checklist

  • robots.txt doesn't accidentally block pages you want indexed — check it directly at yourdomain.com/robots.txt.
  • An XML sitemap exists, is submitted in Google Search Console, and only lists canonical, indexable URLs.
  • Core Web Vitals (LCP, INP, CLS) pass on mobile — test with PageSpeed Insights, not just desktop.
  • HTTPS is enforced site-wide with no mixed-content warnings.
  • No duplicate content served at multiple URLs without a canonical tag pointing to one version.
FAQ

A full pass every quarter is reasonable for most sites, with a lighter technical check (crawl errors, Core Web Vitals) monthly. Rebuilds or redesigns warrant an immediate full audit before launch.

Technical SEO first — if a page can't be crawled or indexed properly, on-page and content quality never get the chance to matter.
