Short answer
Deindexing means Google removed pages from its index entirely, which is different from ranking lower. Check the Pages report in Search Console for the exclusion reason: noindex, crawl error, duplicate, or soft 404. Deindexing has a technical cause far more often than an algorithmic one, and the report names the reason directly.
This is the one diagnosis where Google tells you the answer and most people never look. The Pages report under Indexing lists every URL it chose not to index and states why, in plain language, per URL. No inference required.
The reason it gets missed is that deindexing feels like a punishment, so the search for an explanation starts with algorithm updates rather than with the report that already contains it. In practice most deindexing is mechanical, which is good news: mechanical problems recover in weeks rather than waiting months for a reassessment.
Is my page deindexed or just ranking lower?
These are completely different problems and they are easy to confuse from a traffic graph alone. Two checks separate them in under a minute.
- Run the URL Inspection tool on the page. It states whether the URL is on Google. That is definitive, and it is more reliable than any third-party checker.
- Check impressions in Search Console. A deindexed page records zero impressions, not few. A page ranking on page five still collects impressions, because it is still being shown.
Zero impressions is the signature. If a page is still picking up impressions at a terrible position, it is indexed and demoted, which is a quality problem rather than an indexing one and belongs in a different diagnosis entirely.
Avoid using a site: search as your test. It is a rough sample rather than a complete index listing, and both false positives and false negatives are common.
What do the exclusion reasons actually mean?
Open Search Console, Indexing, Pages, and look at the Why pages aren’t indexed table. Each reason points at a different cause and a different fix, and several of them are not problems at all.
| Exclusion reason | What it means | Measurement (is it a problem?) |
|---|---|---|
| Excluded by noindex tag | Your site told Google not to index it | A problem only if unintentional. Check the tag |
| Blocked by robots.txt | Google could not crawl it | A problem if the page should rank |
| Crawled, currently not indexed | Google saw it and chose not to index | A quality judgement, not a fault |
| Discovered, currently not indexed | Google knows it exists but has not crawled it | Usually crawl budget or low perceived value |
| Duplicate, Google chose a different canonical | Another URL was picked as the real version | A problem if it picked the wrong one |
| Soft 404 | The page returns 200 but looks empty or missing | Usually thin content or an empty template |
| Page with redirect | The URL redirects elsewhere | Normal and expected |
| Not found (404) | The page is gone | A problem only if it should exist |
The last two rows account for a large share of the scary-looking totals people bring to me. A site with 4,000 excluded pages is often a site with 4,000 correctly redirected or correctly removed URLs. The number alone means nothing without the reasons behind it.
What does crawled, currently not indexed mean?
This is the reason that causes the most confusion, because nothing is broken. Google fetched the page, understood it, and decided it was not worth adding to the index.
It is a quality judgement rather than a technical fault, which means there is no tag to fix and no error to clear. Requesting indexing on such a page usually achieves nothing, because Google already crawled it and reached a conclusion. Asking again does not change the conclusion.
The usual causes are near-duplicate pages where several cover the same ground, pages with almost no unique content, programmatically generated URLs at volume, or a site whose overall composition has convinced Google that new pages are unlikely to be worth indexing. That last one is the serious version and it is measurable: run the index bloat ratio, and if a large share of your indexed pages already earn nothing, Google has reason to be sceptical about the rest.
The fix is consolidation rather than persuasion. Fewer, better pages get indexed. More pages of the same kind do not.
How do I find an accidental noindex tag?
The most damaging cause and the fastest to confirm. A noindex can arrive from a staging deployment, a plugin default, an SEO setting applied to a whole post type, or a developer debugging something and forgetting to revert it.
- View source on an affected page and search for the word noindex in a robots meta tag.
- Check the HTTP response headers too, since noindex can be delivered as an X-Robots-Tag header rather than in the HTML.
- In WordPress, check Settings, Reading, and confirm the discourage search engines box is unticked.
- Check your SEO plugin’s per-post-type settings, since these apply site-wide to a whole template at once.
- Check the page itself for a manual noindex set in the editor.
- Use URL Inspection and read the Indexing allowed line, which reports what Google actually saw.
Step two catches the cases that defeat everyone, because an X-Robots-Tag header is invisible when you view source. If the HTML looks clean but Google still reports the page as excluded by noindex, the header is where it is coming from.
Why did Google pick a different canonical?
Canonical tags are hints rather than instructions. Google considers yours alongside its own judgement about which version is the real one, and it sometimes disagrees.
When it picks a different URL, your page is treated as a duplicate of that one and stops being shown independently. URL Inspection reports both the canonical you declared and the one Google selected, side by side. If they differ, that is your answer.
- Make the pages genuinely different. If Google thinks two pages are the same, the most reliable fix is to make that judgement wrong rather than to argue with it.
- Check your internal links. If most of your links point at the version Google chose, you are voting for it too.
- Consolidate rather than compete. Where two pages really do cover the same thing, merging them into one and redirecting is better than fighting over which wins.
- Watch for parameter and protocol duplicates. The same content reachable at multiple addresses creates this situation without anyone intending it.
Can an algorithm update deindex pages?
Rarely, and this is the distinction worth being precise about. Core updates reassess quality and move rankings. They do not usually remove pages from the index.
Where deindexing does follow an update, it is normally the indirect route: pages get demoted, stop earning impressions, and over subsequent crawls Google decides they are not worth keeping indexed. That is a slow drift over months rather than a sudden disappearance.
Sudden mass deindexing points somewhere else. A manual action for pure spam can remove pages, and that comes with a message in Search Console. A hacked site producing spam URLs can see those removed. And a technical fault can do it overnight, which is by far the most common explanation.
So the shape of the loss is informative. A step change to zero on one date is technical or a manual action. A gradual erosion over months is the algorithmic route, and that needs the quality work covered in the content pruning strategy rather than a tag fix.
This is not deindexing if
- Your pages still record impressions. Then they are indexed and ranking badly, which is a demotion and a different problem.
- Only your rankings moved. Positions falling while indexed counts hold is a quality reassessment, not an indexing event.
- The excluded pages are redirects or intentional 404s. Those belong in the excluded list. They are the system working correctly.
- A site: search shows nothing but Search Console says indexed. Trust the URL Inspection tool. Site: searches are unreliable as an index check.
- The pages were only published this week. New URLs take time to be crawled and indexed. Discovered, currently not indexed on a fresh page is often just a queue.
How long does it take to get reindexed?
Once the blocking cause is removed, reindexing follows recrawling rather than any scheduled reassessment. That makes it one of the faster recoveries available.
| Cause | Typical time to return | Measurement (what speeds it up) |
|---|---|---|
| Noindex tag removed | Days to 2 weeks | Request indexing on top pages, resubmit sitemap |
| Robots block removed | Days to 2 weeks | Same, plus confirm crawl stats recover |
| Canonical corrected | 2 to 4 weeks | Align internal links with the intended canonical |
| Soft 404 content added | 2 to 4 weeks | Make the page substantively different, not longer |
| Crawled, not indexed, after consolidation | 4 to 12 weeks | Nothing accelerates this. It is a judgement being revised |
The last row is the one that needs patience rather than action. There is no request that overrides a quality judgement, and repeatedly submitting the same URL does not improve its odds.
If the deindexing was part of a wider traffic loss, confirm the exact break date with the drop analyzer and check whether the whole site or one section was affected with the page scope analyzer. A one-template indexing failure is a very different job from a site-wide one.
Frequently asked questions
How do I know if Google deindexed my pages?
Run the URL Inspection tool, which states whether the URL is on Google, and check impressions in Search Console. A deindexed page records zero impressions. A page ranking badly still records some, because it is still being shown.
What does crawled, currently not indexed mean?
Google fetched the page and decided it was not worth indexing. It is a quality judgement rather than a technical fault, so there is no tag to fix. Requesting indexing rarely helps, because Google already reached a conclusion.
Can a Google update remove pages from the index?
Rarely and indirectly. Core updates move rankings rather than removing pages. Deindexing after an update usually happens slowly, as demoted pages stop earning impressions and Google stops keeping them. Sudden mass deindexing is almost always technical or a manual action.
Why does Search Console say excluded by noindex when there is no tag?
The directive is probably being sent as an X-Robots-Tag HTTP header rather than in the HTML, which makes it invisible when you view source. Check the response headers, or read the Indexing allowed line in URL Inspection.
Should I worry about thousands of excluded pages?
Not on the number alone. Redirects, intentional 404s and correctly noindexed utility pages all appear as excluded, and that is the system working. Read the reasons rather than the total.
How long does reindexing take after fixing the cause?
Days to two weeks for a removed noindex or robots block, two to four weeks for canonical and content fixes, and up to twelve weeks where Google is revising a quality judgement. Nothing accelerates that last case.
Pages gone and the report does not explain it?
Most deindexing is mechanical and recovers in weeks once the cause is found. The rest is a quality judgement that needs a different kind of work entirely. Send your Search Console access and within 48 hours I will tell you which one you have. Free, no obligation.
