What Does a Crawler See Without JavaScript?
Your visitors’ browsers run JavaScript. Most AI assistants and AI search crawlers do not, and Google runs it later and not always. Enter a page and see how much of its text exists before JavaScript runs, and read exactly what such a crawler reads.
The page is loaded twice on our own browser at a desktop viewport, the same as the audit, once with JavaScript off and once with it on, and the visible body text is counted each time. The text shown is from the JavaScript-off load and is not stored; only the address, the two counts and the outcome are kept. This checks the one page you give it.
