Page not too small

What the check finds

The page is unusually small, which sometimes means content failed to render rather than that the page is efficient.

A tiny response often means the server sent an empty shell or an error page. AI crawlers that do not run JavaScript then see nothing to read or cite.

Open the raw HTML (view-source or curl) and confirm the main text is there.
If the content is drawn by JavaScript, render it on the server or pre-render the page.
Check that the URL returns the real page with a 200 status, not a placeholder, block page or soft error.
