Soft 404 Handling
search What we check
Whether a non-existent URL returns a real 404 (or 410), rather than a soft 404 - a 200 response for a page that does not exist.
build How to fix
- 1 Return HTTP 404 (or 410 for permanently gone) for URLs that do not exist.
- 2 Avoid catch-all routes or rescues that answer missing pages with a 200 and a 'not found' page.
- 3 A soft 404 keeps dead URLs in the index and wastes crawl budget.
