Technical SEO Audit vs Content Audit: What's the Difference?

A technical SEO audit examines the infrastructure that determines whether search engines can crawl, index, and understand a site at all - site speed, mobile-friendliness, URL structure, canonicalization, robots.txt, sitemaps, structured data, and security.

A content audit examines the quality and effectiveness of what's actually on the pages once search engines can reach them - keyword targeting, content quality, outdated or decaying pages, keyword cannibalization, and gaps or opportunities in coverage.

The two check fundamentally different things: one asks whether a page can be found and understood by search engines in the first place, the other asks whether the page is actually good once it is found. That difference also decides the order they're worth running in. A new site, one that's undergone major structural changes, or one that's never been audited benefits from a technical audit first, since content quality is difficult to judge fairly - and largely moot from a ranking standpoint - if search engines can't properly crawl or index the pages holding that content. An established site with stable traffic and a technical foundation that's already been checked recently gets more value from a content audit, since the infrastructure isn't the bottleneck and the more useful question becomes whether the content itself still serves its audience and search intent as well as it should.
