Technical SEO Audit: Checklist

A technical SEO audit is a check of the site for technical errors that hinder indexing and ranking in Google.

What to check

Indexing: robots.txt, sitemap.xml, canonical tags, noindex pages. Make sure Google can find and index all important pages.

Speed: PageSpeed Insights, Core Web Vitals (LCP, FID/INP, CLS). Slow sites lose rankings and conversions.

Mobile version: Google uses mobile-first indexing. The site must work well on smartphones.

Structure: URLs, internal linking, page depth. Every important page should be reachable within 3 clicks from the homepage.
