A technical SEO audit checks whether search engines can crawl, render, and index your site: status codes, indexability, speed, and schema, plus the tools used.

When to do a technical SEO audit: before launch, after a redesign or migration, after a sudden traffic drop, and once a year as routine website maintenance.
