On this put up, we’ll assessment these two choices. And supply a verdict on which is healthier for Search engine optimisation.
Let’s begin.

However does having subdomains hurt your Search engine optimisation?
Let’s discover out.

Many SEOs argue that content material hosted on subdomains doesn’t rank properly on Google.
Right here’s their reasoning:
Subdomains could not totally profit from the backlinks (hyperlinks from different websites that time to yours) the primary area has garnered through the years.
Google treats subdomains as distinct web sites. Which suggests they crawl and index subdomains individually.
Because of this, you might 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 may’ve if it have been hosted on subdirectories as an alternative. (You’ll hear extra on subdirectories later on this information.)
Additionally, the extra subdomains you will have, the more durable it may be to take care of your web site total.
You could find yourself with duplicate content material (content material that’s equivalent to content material discovered elsewhere) and/or improper interlinking (hyperlinks to different pages on the identical web site) between the primary area and its subdomains.
These errors can damage your web site rankings and the person expertise.
Plus, gathering and analyzing information for Search engine optimisation reviews could be harder whenever you’re coping with a number of subdomains. As a result of it could require extra instruments or settings to merge information successfully.
For all these causes, SEOs often suggest utilizing subdirectories as an alternative of subdomains.
What Is a Subdirectory?
A subdirectory (additionally referred to as a subfolder) is a folder positioned inside the primary area. It clearly falls below your area identify.
Much like subdomains, subdirectories allow you to set up your web site content material into totally different classes or sections.
For instance, you may create a subdirectory like yoursite.com/weblog to host your weblog content material.
In case you’ve crawled your web site with the Website Audit software, you could find all subdirectories you’re utilizing.
Simply navigate to the “Crawled Pages” tab and click on on “Website Construction.”
You’ll see an inventory of subdirectories in your web site.
However what distinction do subdirectories make to Search engine optimisation?
Let’s discover out.

Whereas Google typically views subdomains as separate entities, subdirectories are seen as a part of the primary area.
Because of this all of the laborious work you set into constructing backlinks is extra prone to profit each piece of content material below that important area, together with these in subdirectories.
That’s as a result of the hyperlink fairness often 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 part sits tidily below one area umbrella, there are fewer technical complications.
For instance, you wouldn’t have to fret about organising and sustaining separate internet hosting.
And you may simply create new subdirectories for various sections of your web site, akin to your weblog, your information part, and so forth.
Doing this on subdomains would require extra effort and assets.
Higher but, monitoring web site information is extra easy with subdirectories. As a result of you may simply get a holistic view of your web site’s efficiency in a single place.
These advantages are why SEOs typically insist on utilizing subdirectories.

To recap:
One main motive why they dislike subdomains is as a result of they consider Google views subdomains as separate entities—not as a part of the identical web site. So, the content material hosted on them may not profit from the primary area’s collected area authority.
However what does Google consider this?
Google’s John Muller as soon as mentioned that it’s advantageous to make use of both subdomains or subdirectories.
Google internet search is okay with utilizing both subdomains or subdirectories.
Suggesting it doesn’t make any distinction from a rating standpoint. Positively or negatively.
Take into account that Google has developed its understanding of area buildings through the years.
Because of this whereas they might deal with subdomains as separate entities, they’ll nonetheless establish and acknowledge the connection between the primary area and its subdomains.
And with correct inside linking, you may make it clear that your subdomains belong to the identical web site.
Inner linking facilitates bots’ skills to crawl all of the pages in your web site (together with these on subdomains). And helps distribute hyperlink fairness amongst them.
Which places an finish to the parable that subdomains are dangerous for Search engine optimisation.
So long as you utilize them accurately, subdomains are advantageous in your Search engine optimisation efficiency.
