Pages that have never been indexed are a different problem from pages that were indexed and dropped out. Nothing has been lost; something is preventing inclusion in the first place, and the reason is usually stated plainly in Search Console.
If your pages were previously in the index and vanished, see pages disappeared from Google instead. If the entire site is missing, see website not indexed by Google.
Read the exclusion reason
The Page indexing report groups URLs by why they were excluded. The reason determines the fix completely, and the fixes are mutually exclusive.
- Discovered, currently not indexed: known but not yet crawled. A crawl capacity problem.
- Crawled, currently not indexed: read and passed over. A content or duplication problem.
- Alternate page with proper canonical tag: excluded by your own declaration, usually correctly.
- Excluded by noindex tag: a directive is doing this deliberately or accidentally.
- Blocked by robots.txt: crawling is prevented.
- Soft 404: the page reports success but appears empty. See soft 404.
Working without the reason is the single biggest waste of effort in this area, because the remedy for a crawl problem does nothing for a content problem and vice versa.
The three underlying situations
It cannot be crawled
Blocked by robots.txt, behind authentication, returning errors, or not linked from anywhere. Fix access first; nothing downstream matters until the page can be fetched.
It can be crawled but is not being reached
Crawl capacity is going elsewhere, usually to filter and parameter URLs. The page is fine; it is queued behind rubbish. See crawl budget.
It is crawled and rejected
The page adds nothing that is not already indexed. Usually duplication, thinness, or being one of many near-identical pages. This is a content decision, not a technical one.
What actually moves it
- Internal links. A page linked only from a sitemap reads as unimportant. Sitemaps aid discovery; links signal value.
- Reduced click depth. Pages far from the homepage are crawled less.
- Genuine differentiation. If you cannot say how the page differs from your others covering the same ground, neither can Google.
- Less competing rubbish. Reducing low-value URLs raises the share of crawling your real pages receive.
- Consolidation. Merging near-duplicates into one stronger page frequently gets the survivor indexed.
What does not
- Requesting indexing repeatedly without changing anything.
- Resubmitting an unchanged sitemap.
- Adding more pages while existing ones are unindexed.
- Minor edits made purely to trigger a recrawl.
Frequently asked questions
How long should I wait before worrying?
Two to four weeks for a new page on an established site. Longer on a new domain. An established page that has never been indexed is telling you something now, and waiting will not change it.
Does Google have to index every page?
No, and it does not. Indexing is selective, and a proportion of any large site will remain unindexed. That is normal. The question is whether the pages you care about are included.
Is a low indexed count always bad?
Not if the unindexed pages are ones you did not want indexed anyway, such as filters or paginated views. Compare against your genuine content count rather than your total URL count.
Should I noindex the pages that will not index?
Only if you did not want them indexed. Noindexing pages you do want is conceding the problem rather than fixing it.

If pages you need indexed are not being included, book an SEO consultation to identify whether it is access, capacity or content.
