Rendering gate
Search engines render JavaScript. Most AI crawlers do not. A React site that looks perfect in your browser can be an empty shell to the thing deciding whether to cite you.
Two fetches, then a comparison
We take the server HTML exactly as a non-rendering crawler receives it, then render the same URL in a headless browser through Playwright. The gap between those two is what an AI crawler is missing.
It gates everything below it
If a page is client side only, telling you its product schema is incomplete would be noise. The schema is not incomplete, it is invisible. We report the cause and hold the symptoms until you fix it.
