How long until Google indexes a crawled page?

There's no fixed time. Some pages get indexed after a few days, some never. If a page stays in this status for weeks, Google probably considers it low value.

Does requesting indexing in Search Console help?

It can speed up re-evaluation, but it doesn't change the outcome. If nothing on the page changes, the decision is usually the same.

Is this a server or robots.txt problem?

No. If the page was crawled, Google had access to it. The issue is how the content was judged, not whether it was reachable.

“Crawled – currently not indexed” — causes and what to do

Google visited the page but decided not to add it to the index for now. It isn't a technical error but a judgement: the content looks thin, too similar to other pages or poorly connected to the rest of the site. Improving content and internal links usually helps more than re-submitting the URL.

What this status means

Googlebot fetched the page but didn't add it to the index. It may be indexed later — or not at all. Google doesn't give a specific reason, because this is the result of an assessment, not an error. Pages land here most often when, in Google's view, they add little compared with what's already indexed.

Common causes

thin content: a few sentences, a manufacturer's description copied across hundreds of shops, empty categories,
duplicates: the page is very similar to another one on or off your site,
weak internal linking: only the sitemap or a single deep link points to it,
many new pages at once: Google evaluates them gradually, and a site without history gets less trust,
content that only appears after JavaScript, which the crawler didn't fully read.

What to do

Check the page in URL Inspection and look at the rendered screenshot — does the crawler see the full content?
Expand the content with specific information that other pages don't have.
Link to the page from important places: navigation, categories, related articles.
Merge or remove near-identical pages — keep one, better page.
Only then request indexing again.

When it signals a technical problem

If many pages that used to be indexed suddenly move into this status, look for a change on the site.

Typical culprits are a template that stopped showing content without JavaScript, a changed canonical or new redirects. IndexRise compares the title, H1 and canonical of monitored pages every night, and on sites that swap content in the browser it compares the rendered version. Such a change shows up before Google starts dropping pages.
