Subdomains might not absolutely profit from the backlinks (hyperlinks from different websites that time to yours) the primary area has garnered over time.
Google treats subdomains as distinct web sites. Which suggests they crawl and index subdomains individually.
Consequently, you will have to work on gaining backlinks for every subdomain individually to enhance their rankings. Which requires a variety of effort and time.
With out that added effort, content material on these subdomains might not rank in addition to it might’ve if it had been hosted on subdirectories as an alternative. (You’ll hear extra on subdirectories later on this information.)

Which means whereas they could deal with subdomains as separate entities, they’ll nonetheless establish and acknowledge the connection between the primary area and its subdomains.
And with correct inner linking, you may make it clear that your subdomains belong to the identical web site.
