When you see this
Discovered - currently not indexed appears in two places:
- Search Console, Pages report, under “Why pages aren’t indexed” - for properties you own.
- The URL Inspection tool / API, field
coverageState- the response also shows an emptylastCrawlTime.
For third-party donor pages you cannot open Search Console. The equivalent signal is: the URL is absent from a live index check AND the site owner’s report shows this status, or the page is absent from the index for 14+ days after placement.
Why it happens
- Deferred crawl: Google postponed the fetch to avoid overloading the host - the official explanation in the Search Console help. Evidence: rising average response time in the host’s Crawl Stats.
- Weak internal linking: the page is 3+ clicks deep or linked only from pagination. Evidence: zero internal links from crawled hub pages.
- Low host crawl rate: the whole site gets few Googlebot visits. Evidence: sparse Googlebot hits in server logs.
- Queue displacement: large sites generate URLs faster than their crawl budget covers. Evidence: the status concentrates on one section or URL pattern.
Fix
1
Confirm the state
For your own property, inspect the URL:
coverageState reads Discovered - currently not indexed, lastCrawlTime is empty. For a batch, run the bulk indexation check for backlinks and keep the URLs reported as not indexed.2
Remove delivery blockers
Request the page with a Googlebot user agent. Expected:
HTTP/2 200 in under ~2 seconds, no X-Robots-Tag: noindex, no Disallow covering the path. Any failure here explains the deferral and must be fixed first (or the donor replaced).3
Create crawl paths
If you control the host: link the page from a frequently crawled hub and refresh
lastmod in the sitemap. Expected outcome within 1-2 weeks: lastCrawlTime gains a date.4
Submit for crawling
For third-party donors, submit the URL list to an indexing service. Expected outcome: a day-7 report splitting the list into indexed / not indexed / errored.
Verify
Fixed looks like one of two states: the page appears in a live index check with its title, or the inspection verdict changes toSubmitted and indexed. A move to Crawled - currently not indexed is partial progress - the fetch happened; the remaining problem is selection, not delivery.
