Page looks like a soft 404

What this means

The URL returns 200 but the content reads as a not-found page and carries almost no text. Google calls this a soft 404: it wastes crawl budget on URLs that should have been retired, and can leave empty pages in the index competing with real content.

How to fix it

Return a real 404 or 410 status for pages that do not exist. If the page does have content, add it — a 200 response should never look like an error page.

Fix effort

This check needs a developer fix: it turns on a routing, hosting or infrastructure decision that no automatic edit can make safely.
