Page Extractability Check
Measure how much of your content an AI crawler can actually read without JavaScript.
What does this tool check?
AI crawlers mostly do not execute JavaScript. We measure the visible text in the raw HTML, the text-to-HTML ratio, whether the first paragraph answers anything, and structural aids like lists and tables that make answers easy to lift.
How should I read the result?
We can only measure what exists without JS — we do not claim your page "is an SPA", only how much text a non-rendering crawler receives. Under ~300 characters is effectively an empty shell.
What should I do next?
Server-render or pre-render the primary answer content; keep interactive extras client-side.
