Do links from subdomains pass the authority and link juice of main domain ?

[teamtc]

Hi,

There is a subdomain with a root domain's DA  90. I can earn a backlink from that subdomain. This subdomain is fresh with no traffic yet.

Do I get the ranking boost and authority from the subdomain?

Example: I can earn a do-follow link from **https://what-is-crm.netlify.app/ **but not from https://netlify.app

Any subdomain links shared won't contribute to your main site's link authority or ranking in search results because they are (basically) considered two sites, they just have a lot of links between them.
