Crawling issues

One of my sites is relatively new, about 6 months old. I already build some links (not too much) and request indexing via search console for every new post.

Still, there are about 50 posts which Google found in the site map, but did not crawl yet. Many of them are live for about a month.

Usually it takes only a few days until Google at least crawls my pages. Anyone experienced this too? Is it because the site is too young, or may there be any other issues? On the technical side everything seems fine

Seems like you have onpage issue as the cause since the month waiting for me is very long even if I build a new site this week I would still expect it all to be indexed more less within 2 weeks normally .

Yes but I don't know what it could be. Some parts of the content is just translated stuff, but can this be an issue?

For what I know, G would crawl but not index, if there is a problem with content.

Something same is happening with my 2 new sites. 1 is 4months older and another one is 2 months. Some pages are indexing and some are not. Don't know what's happening

I am having issues with my pages indexing too. Not sure what the issue is here but it has been over 6 weeks.

Make sure you verify ownership for your all for example:
http://www.yoursite.com,
https://www.yoursite.com,
http://yoursite.com,
https://yoursite.com,

Since google treats them all like different sites, you may run into redirect errors or indexing errors.

Did you guys try to use the API? I will try it out and tell if it helps
