How to do a technical SEO audit

In one line

A technical SEO audit systematically checks crawlability, indexing, speed, structure and schema across your site, then prioritises fixes by impact.

The steps

  1. 1Crawl your site with an SEO crawler to find issues
  2. 2Check indexing and coverage in Search Console
  3. 3Test Core Web Vitals and mobile-friendliness
  4. 4Review robots.txt, sitemap, canonicals and redirects
  5. 5Validate structured data
  6. 6Prioritise: fix crawl/index blockers first, then speed and structure

Why it matters

Technical problems silently limit your whole site. A regular audit catches indexing blockers, broken links, slow pages and schema errors before they cost you rankings.
