5xx server error

A 5xx on a content URL is the server failing, not the page being missing. If Google keeps hitting errors it slows crawling and can drop the page, so I treat sustained 5xx as urgent.

What it is

A server error on a content URL.

Why it matters

Repeated 5xx can drop pages from the index and, if widespread, slow whole-site crawling.

How to fix it

Fix server stability; return correct codes.

How to find it on your site

  1. Crawl the site and filter for 5xx responses.
  2. Check the Search Console Pages report for Server error (5xx) entries.
  3. Reproduce with curl -I on the affected URL and watch for intermittency.
  4. Check server, application and CDN logs to find the root cause.

Cross-reference to ranking and citation factors

Server errors reduce crawl rate and can de-index affected pages if they persist, which sits upstream of every on-page signal.

Impact

Severe at scale. Direct.
