Discovered-Currently not Indexed or Crawled What Should We Do?

Matty
While this would be hard to diagnose and answer without looking at your website and Google Search Console (GSC), here are a few general suggestions to look at:
1) First thing I'd do is a 'site:' search operator check in Google to make sure the URLs aren't indexed.
Sometimes GSC is a little slow to update and may display URLs which have been resolved.
2) How long after you publish a post are you checking to see if it's indexed? If it's a small site it may take a little time to get indexed.
Don't expect a page to be indexed in 5 minutes.
3) Are the pages/posts being noindexed? Check the source code to ensure you have an index tag on your pages/posts and that they're listed in your XML sitemap
4) Check to ensure you have a canonical tag on each page and that it's correct
5) Internal linking. Are you linking to these pages? If your website allows it, add a 'recent posts' widget on your homepage so you automatically link to your new content from your homepage – that'll give it more visibility from the start. Or you can just add a contextual link somewhere on the homepage.
Make sure they aren't orphan pages.
6) Resubmit your sitemap to Google Search Console (GSC). Can GSC read and check your sitemap or do they show errors?
7) Do you have duplicate content? Is this content too similar to another page that's already indexed?
8)Is your content public? If your robots.txt file isn't setup correctly there are times when crawlers can find private content (a rare case though)
Also just to add – what type of URLs are these?
Are they regular page URLs?
Are they Rich Site Summary (RSS) feed URLs?
Are they paginated URLs?
The two latter ones I wouldn't even worry about.
That's my 2c off the top of my head.
Edit: we can also go deeper into crawl budget, but this post is getting long 😅

All good points from Matty – also worth noting – none of the search engines promise to index anything or everything, and, sometimes Google Search Console (GSC) will give you false/positives – take a chunk of text (15 words or so) wrap it in quotes and Google it (an exact match search) – it's not uncommon for GSC to state something isn't indexed when it is

I've got the same problem with two posts since a few weeks. Tried to add more internal links, but it didn't work. I think the problem is this: Google crawls it but doesn't index, because it thinks the post is low quality. In my case the two posts have less words than most posts on my site and cover a similar search intent. Therefore I'll try to consolidate the two posts. Consolidating posts is what John Mueller recommends in this case, according to this article: https://www.SEO-suedwest.de/4314-google-erklaert-warum-gefundene-seiten-oft-nicht-indexiert-werden.html (German, you need to translate)

Try putting an outbound link to Wikipedia or some other very authoritative site in all posts. I did a little bit of testing with my own website and posts that include Wikipedia links are being indexed same day (for me anyways). I also had an issue before I started linking out to Wikipedia, a post was in "Discovered" for 4 weeks. Finally I copied and pasted the entire post, gave it a new URL and included an outbound Wiki link and it got indexed same day.

Did you request indexing manually from Google Search Console (GSC)? I'd recommend giving it a shot, especially for 'Discovered-current not indexed' pages. Those pages are not yet crawled by Google. So I assume there are no on-page factors associated with the issue. Crawl budget limit or something like that might be a reason. So, I'd suggest you request indexing them manually from GSC. That will place those URLs in the queue to crawl. Googlebot could see your preference and try to crawl those URLs first even though you have a very limited crawl budget. And one more thing, don't submit all affected URLs to index. That might end up confusing the Google bot. Instead, request indexing only the 'Discovered- currently not indexed' pages first. And then wait and see if this works. That strategy worked for me as I was facing the same issue. 'Crawled-but not indexed' pages are different. They are crawled by Google. But for some reason, Google decided not to index them. Most of the time they are low-value pages or pages that should not be indexed by Google, such as comments feed. So, I don't recommend you dilute things. Request indexing only the 'Discovered- currently not indexed' pages first. Hope this helps.

I have the same issue. But I don't do anything with it. I let it index naturally. I have about 160 post. But didn't start to post actively before March this year. But the site is about 1.5 year old. When I post, sometimes they get indexed within 10 hrs. But I have also had best of post that I published in april that did not index before last week. But I regularly post from every week to every 2nd week. About 10 – 15 times a month. Since I started the website I have never used GSC to index the post. I'm curious, let me know how it goes •.
Another thing that I came to think about is that it can have something to do with if you are just in a niche (will get faster indexed) rather than an entire industry (get slower indexed).

This happened to me on my site, nearly 100 pages and I noticed after a few months that 20~ or so were unindexed. Nothing worked to fix it except waiting. My site was new and maybe just needed more signals? I wrote almost all the content and I assure you that it's as good if not better than most of the drivel my competition is putting out. I know it sucks, but that's how it be I suppose.
