How it works
Once a day, we look for mistakes that hide your site from search engines, usually a staging configuration shipped to production:
robots.txtblocking every crawler (Disallow: /), or answering with a server error, which Google reads as "disallow everything";- a
noindexdirective on the page, in a<meta name="robots">tag or anX-Robots-Tagheader.
Either one makes your pages disappear from Google within days. We also request a page that does not exist: it should answer 404. A missing page that answers 200 (a "soft 404") gets error pages indexed as duplicate content.
Statuses
| Status | Meaning |
|---|---|
| OK | Search engines may index the site, and missing pages return 404. |
| Warning | Missing pages return a success status (soft 404), or we could not connect. |
| Failed | robots.txt blocks everything or returns a server error, or the page has noindex. |
By default you are notified of warnings and failures.
Fixing common problems
- robots.txt returns 5xx: serve a valid file, even an empty one, with a
200status. - robots.txt blocks everything: replace
Disallow: /with the paths you really want hidden, or remove the rule. - noindex: remove it from the page template or the server configuration. In WordPress, untick Discourage search engines from indexing this site under Settings › Reading.
- Soft 404: make your application or catch-all route return a real
404status for unknown pages. - After a fix, request indexing again in Google Search Console to speed up recovery.
