why my subdomain don't indexed

hello guys i have a subdomain like this blog.domainname.us the subdomain is archived but posts don't i use rank math and i have sitemap submitted and everything is clean the domain is indexed posts no
any help

Google treat sub domain as separate site. Don't use it for blog.
Use it for app, membership etc.

Yes. Subdomains are treat as seperate sites

Check your rel canonicals.

As Subdomains behaves as separate sites, Create a robot.txt file for the crawler to index.
If indexed, wait for a while to index the post

There are many possible reasons why your subdomain is not indexed by Google. It is possible that your subdomain is not well linked from your main website, or that your website is not well linked from other websites. It is also possible that your website is not well optimized for search engines. If you are not sure why your website is not appearing in Google search results, you can contact Google for more help.

Subdomains take time ,try pinging them over webmasters .

yes google does index your own subdomains.
Look at this example nytimes they have multiple blogs.

What I not understand is, they have some of their blogs as subdirectory category and some of them as subdomain, how this make sense? Type in nytime blogs in google.

Then multiple sites are coming up (google says that they only showing max. 2 domains of your site eh?) like;

open nytimes com (it is a subdomain check it)
lens.blogs.nytimes com, but this url structure is= https://archive.nytimes.com/lens.blogs.nytimes.com/
Then check it with receipes nytimes= google is listing multiple site pack at the top (what is the name of this I have forgotten?) but the recipes site url structure is subdomain.

One of the nytimes nameserver is; DNS1.P06.NSONE.NET , but I not found in google a web hosting provider with the name nsone ?

I must ask you guys, this makes no sense for me, sometimes so, then sometimes make a subdomain....forward and back, back and forward....
I not understand this tactic.

Why not use an unit url structure ? Danlok example, he uses category pages and multiple domains.
I try to understand the tactic of nytimes and yes, check their source code they not use wordpress as cms.

Nyt is s massive website with probably millions of pages and posts spanning decades. It's a mess and costly just to maintain all the crap from 20 30 years, dont base your site structure assumtions on it.

Most of these newspapers have already stopped printing and are now charging for reading blog/news due to very expsnsive operations.

IM Rider;

use the tactic of nytimes has not to do if a website is big

NYTimes subdomains have tons of links form their main domain.

Kini Actaz;

yes....but why they use sometimes a subdomain, then use categories? Wheny they not make their url structure united ?
