Right here’s their reasoning:

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 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 could not rank in addition to it might’ve if it have been hosted on subdirectories as a substitute. (You’ll hear extra on subdirectories later on this information.)

A subdirectory (additionally referred to as a subfolder) is a folder situated inside the principle area. It clearly falls underneath your area identify.

Just like subdomains, subdirectories provide help to arrange your web site content material into completely different classes or sections.

For instance, you may create a subdirectory like yoursite.com/weblog to host your weblog content material.

For those who’ve crawled your web site with the Web site Audit instrument, you could find all subdirectories you’re utilizing.

Simply navigate to the “Crawled Pages” tab and click on on “Web site Construction.”

However what distinction do subdirectories make to Web optimization?

Let’s discover out.

As a result of every little thing sits tidily underneath one area umbrella, there are fewer technical complications.

For instance, you wouldn’t have to fret about establishing and sustaining separate internet hosting.

One main purpose why they dislike subdomains is as a result of they imagine Google views subdomains as separate entities—not as a part of the identical web site. So, the content material hosted on them won’t profit from the principle area’s amassed area authority.

However what does Google consider this?

Because of this whereas they might deal with subdomains as separate entities, they will nonetheless establish and acknowledge the connection between the principle area and its subdomains.
