Hi, I run blog https://techwriter.documatt.com. I believe it has useful content, looks good. It exists for about 3 months. I promote it with helping others in forums, produce valuable libs with links in README, I'm on various "awesome" lists, etc.
Google doesn't index website content except for a few useless pages like about or posts per year. The valuable rest of the website is ignored. I correctly submit all pages in a sitemap. Google knows about them, but don't index them. I.e. I can't compete in search results at all.
Google Search Console tells me pages are "discovered - currently not indexed" "https://support.google.com/webmasters/answer/7440203#discovered__unclear_status". However, they are in this status for weeks and months.
How to break this "curse"?
Have you submitted a request for the URLs to be indexed? Have you submitted your sitemap to Google Search Console (and is your sitemap up to date)?
