Subdomains could not absolutely profit from the backlinks (hyperlinks from different websites that time to yours) the principle area has garnered through the years.
Google treats subdomains as distinct web sites. Which implies they crawl and index subdomains individually.
Consequently, you could have to work on gaining backlinks for every subdomain individually to enhance their rankings. Which requires loads of effort and time.
With out that added effort, content material on these subdomains could not rank in addition to it might’ve if it had been hosted on subdirectories as a substitute. (You’ll hear extra on subdirectories later on this information.)
Additionally, the extra subdomains you might have, the tougher it may be to keep up your web site general.

Which means that all of the laborious work you place into constructing backlinks is extra more likely to profit each piece of content material beneath that most important area, together with these in subdirectories.
That’s as a result of the hyperlink fairness normally will get distributed all through the area.
One other upside of utilizing subdirectories is that they permit for simplified administration.
As a result of every little thing sits tidily beneath one area umbrella, there are fewer technical complications.
For instance, you wouldn’t have to fret about organising and sustaining separate internet hosting.

However what does Google consider this?

Google internet search is ok with utilizing both subdomains or subdirectories.
Suggesting it doesn’t make any distinction from a rating standpoint. Positively or negatively.
Needless to say Google has advanced its understanding of area buildings through the years.
Which means that whereas they could deal with subdomains as separate entities, they’ll nonetheless determine and acknowledge the connection between the principle area and its subdomains.
And with correct inside linking, you can also make it clear that your subdomains belong to the identical web site.

So long as you utilize them appropriately, subdomains are wonderful to your Web optimization efficiency.
