Technical AEO Audit: A Complete 5-Category Audit Framework With Free Tools
A technical AEO audit is a systematic review of the technical factors that affect whether AI systems can find, read, and cite your content. It covers five areas: your structured data (schema markup), how easily crawlers can access your pages, your page speed scores, how your content is structured, and your expertise signals. Most technical AEO issues are invisible in normal website use but are critical for AI citation.
Technical AEO failures are often invisible from the user side but have significant impact on citation rates. A page that looks perfect to a human visitor may have JS-injected schema invisible to AI crawlers, a noindex flag from an unfixed dev flag, or a 1.2MB JavaScript bundle that causes crawler timeouts. The audit systematically surfaces these invisible issues.
