1–4: technical blocks

A crawler cannot index a page it cannot request or is explicitly told not to index.

  • robots.txt blocks Googlebot
  • Meta robots or X-Robots-Tag contains noindex
  • The URL returns 4xx, 5xx or a soft 404
  • The page redirects somewhere else
02

5–8: canonical and duplication problems

Google groups duplicate and near-duplicate URLs and selects a canonical. Your submitted URL may be crawled but not chosen.

  • Canonical points to another URL
  • Multiple parameter or protocol versions compete
  • The page substantially duplicates another page
  • The content is too thin to justify a separate URL
03

9–12: discovery and quality problems

A page may be technically indexable but still receive low crawl priority or be excluded after evaluation.

  • The page has no meaningful internal links
  • The site publishes too many low-value URLs
  • JavaScript rendering hides core content or links
  • The server is slow or unreliable during crawl attempts

A better recovery workflow

Fix the specific issue, link the page from relevant indexed content, update the sitemap and then request another crawl for an owned priority URL.

Track the change date and result instead of creating repeated identical submissions.

Frequently asked questions

Does 'Crawled - currently not indexed' mean the page is blocked?

Not necessarily. It means Google crawled the page but did not include it at that time. Review uniqueness, value, canonical signals and site quality.

Can internal links help indexing?

Yes. They provide discovery paths, context and site hierarchy, although they do not guarantee indexing.

Should I remove noindex before submitting?

Yes, if the page is intended for search. Google must crawl the page to see that the noindex directive has been removed.

Can server errors delay indexing?

Yes. Repeated 5xx responses, timeouts and unstable rendering can prevent or delay crawling.
