On-page diagnostic
Scan a page in seconds.
Tip: open the page, right-click, choose “View Page Source”, select all, copy, then paste above. This reads the actual HTML Google’s crawler sees.
Best-effort only: most sites block cross-origin requests from the browser, so this will often fail. Pasting page source is the reliable path.
