See what content exists in the raw server HTML before JavaScript runs.
A raw HTML content checker fetches the page as a server returns it and reports the text, headings and links present before any JavaScript runs. If key content only appears after scripts execute, some crawlers, including many AI crawlers, may not see it.
This tool fetches the address you enter once, from our server, and reports what a crawler would receive. The URL is not stored; only a short-lived rate-limit counter is kept. Results show the page at the moment of the check and can differ from what a logged-in browser or a bot with different headers sees.
Reads the real page at the moment you run it, with every redirect followed and shown.
Each finding says what it means and what to do next, not just a raw value.
Copy the output straight into your CMS, spreadsheet, ticket or client report.
Free, with no signup. Fair-use limits keep the tool fast for everyone.
Use a full public URL.
The page is fetched live from our server.
Apply the fixes, then run it again.
Compare what appears in the raw response with what you see in a browser. Your main heading, body text, key internal links, title, meta description and structured data should already be in the raw HTML. If they are, any crawler can read them without running scripts. If the text count is very low or links are missing, the page depends on JavaScript rendering. Fix this by using server-side rendering, static generation or pre-rendering for important content, and make navigation use real anchor links with href values. Re-run the check after the change and also use URL Inspection in Search Console to see how Google renders the page.
Assuming that because Google can render JavaScript, every other crawler can too, is the main mistake. Many AI and social crawlers read only the raw HTML. Another is hiding content behind click events or loading it only after scroll, so neither the raw response nor the first render contains it. Navigation built with onclick handlers instead of anchor links hides URLs from discovery. Putting canonical, robots or title changes in JavaScript can create conflicts between raw and rendered versions. Do not judge by the browser view alone, since it shows the rendered result. A small raw page is not always bad, but critical content missing from it needs attention.
