Extractability
Extractability is whether a page's meaningful content is present in the HTML the server returns, before any JavaScript runs.
It matters because the major AI retrieval crawlers do not execute JavaScript. GPTBot downloads JavaScript on roughly 11.5% of requests and runs none of it. ClaudeBot downloads it on roughly 23.8% and runs none. A page whose body arrives only after hydration is, to those crawlers, an empty page.
This is the failure that catches client-side SEO tools: a fix injected by a script is invisible to exactly the engines an AI visibility dashboard measures. Three checks here cover it, one for content that needs JavaScript, one for meta tags set by script, and one that names the injection tools doing it.
