Interpreting not-indexed results

A result is a hypothesis

An index checker that reports "not indexed" is saying it could not find the URL in Google's results with the queries it ran. That is evidence, not a diagnosis. The useful work starts with asking why, because each cause calls for a different response, and some call for none.

Triage order

Work through these causes from cheapest to rule out to most expensive:

1. Checker false negative

Search-based checks miss some indexed pages because results vary by query form, datacenter and time. A second check, or a different query form, resolves many of these. Index checker accuracy covers the reasons.

2. Too new

Indexing lags crawling. A miss on a page a day old says little. Re-check timing suggests waiting one to five days before reading misses as real.

3 to 5. Mechanical causes

A wrong URL string, an error page, or an indexing block will produce a miss every time. noindex and robots checks lists what to inspect. Google's noindex documentation also notes that a robots.txt block prevents Google from seeing the tag at all, so the two must be read together.

6. Canonicalized

If Google treats the URL as a duplicate, it indexes another address. Search Console's Page indexing report has specific reasons for this, such as "Duplicate, Google chose different canonical than user". For third-party pages, canonicalization and index checks shows how to detect it from outside.

7 and 8. Crawl and quality

For pages you own, the Page indexing report separates "Discovered - currently not indexed" (Google knows the URL but has not crawled it yet) from "Crawled - currently not indexed" (Google fetched it and has not indexed it). The first is the case submission is designed for: getting Googlebot to fetch the page. The second is a quality or priority decision; the help page says such a URL may or may not be indexed later and that there is no need to resubmit it for crawling. For third-party pages these reasons are not visible, so a crawlable, indexable miss past normal lag is treated as possibly either.

Reading misses in aggregate

Single URLs are noisy. Patterns across a list are more informative:

• Misses concentrated on one domain point to that site (blocks, low quality, canonical templates).
• Misses concentrated on recent URLs point to lag.
• An overall indexed share that falls over time on the same list points to pages dropping out or links being removed.

Bulk index checking explains how to segment results so these patterns show.

Deciding what to do

After triage, each miss belongs to one of three buckets:

1. Wait: new pages and likely checker misses. Re-check later.
2. Fix or drop: blocked, broken, canonicalized elsewhere. Resubmission will not help.
3. Resubmit: reachable, indexable, past lag, still missing. These go into the check-to-resubmit loop.

For individual URLs, the step-by-step single-URL method is the right starting point. The IndexChex index checker reports a simple indexed or not-indexed status per URL, so this triage is the reader's job whichever tool produces the list.
