The Great Subdomain vs. Subfolder Debate: Which Is Better for SEO?

The Great Subdomain vs. Subfolder Debate: Which Is Better for SEO?

Getting to the bottom of one of the search community’s longest arguments

It’s a debate that stands the test of time on the internet: Is it better to host your content on a subdomain or in a subfolder? Is one better than the other for SEO?

To put it simply, the question of whether or not to host on subdomains or in subfolders comes down to what makes the most sense for your content. It’s a debate that can definitely go around in circles, but luckily the answer is a lot more simple than you may think. First, let’s look at the definition of each option.

What Is a Subdomain?

Think of a subdomain as a child of your main site. Subdomains are often used for staging environments, e-commerce, and mobile experiences. These sites are treated as completely separate entities from your main site.

A subdomain will always be placed before the main domain in a URL. For example, The New York Times hosts its cooking content on This is an example of a subdomain.

What Is a Subfolder?

A subfolder is not a separate site like a subdomain, but rather a page or section that sits within your main site.

The subfolder’s name will always come after the main domain in a URL. For example, RebelMouse-powered Brit + Co hosts its stories about food in the subfolder

What defines a subdomain and what defines a subfolder may not seem like an impactful decision for your site, but each choice can have different implications for your search performance.

Subdomain vs. Subfolder: What’s Really Better for SEO?

There’s no cut-and-dry answer to if a subdomain or subfolder is better for search. However, many members of the SEO community agree that there is a huge benefit to hosting your content in subfolders.

The most important thing to keep in mind about subdomains is that they are completely separated from your site’s main domain. Remember, Google considers quality content as its top ranking factor. If you move a large part of your site to a subdomain, you will lose all of the valuable existing links and established presence that come with them. This can weaken your main domain’s authority. As Semrush points out, this is often why sites can experience a lift in organic visibility and traffic when relevant subdomains are migrated to subfolders attached to the original domain.

Officially, Google remains neutral on the topic. Google’s Search Advocate John Mueller said that Google is “fine” with both subdomains and subfolders. Watch his full take in the following video:

More recently, Mueller chimed in on Mastodon to say that while subdomains bring their own technical complications, the choice truly depends on the content itself.

So, if your content can’t truly stand on its own — think of The New York Times’ Cooking subdomain as an example — then choosing a subdomain may be the right choice for you. However, a subdomain’s content should truly be separate from your main site’s core content, and should be able to function as a standalone website as well. When done correctly, this can be a great way to build legitimate backlinks to your main site.

However, many sites don’t have the right volume of separate content that would make logical sense to be hosted outside of the main domain. This is one of the reasons why many experts in the SEO community will argue that the data favors subfolders.

A Look at the Data

The debate over subdomains and subfolders is always going to be a hot topic among web developers and SEO analysts. There are plenty of threads and debates that you can find after a quick search on Twitter. However, there is no shortage of compelling data that demonstrates subfolders can increase traffic to your site:

Meet the RebelMouse Platform: The Highest Performing CMS on the Web

Make sure your site is set up for success in 2022.

In the spring of 2020, Google let the world know that its Core Web Vitals would become the new benchmark for measuring a site's performance in its search results, known as the page experience update. Fast forward to more than a year later in August 2021 when, after much anticipation, Google's page experience update became official.

Since its rollout, developers have felt the impact of how their publishing platforms stack up against the new standard. Important decisions around the architecture of your site can now make or break your site's performance in the eyes of Google.

HTTP Archive, a tracking platform that crawls the web to identify trends and record historical patterns, frequently reports on how top content management systems (CMS) have weathered the page experience update through the creation of its Core Web Vitals Technology Report. RebelMouse has consistently outperformed major CMS platforms on Google's most critical metrics throughout the year:

Getting superior scores on Google's performance benchmarks isn't easy, either. The Ahrefs blog analyzed Core Web Vitals data from the Chrome User Experience Report (CrUX), which is data from actual Chrome users, to see how the web stacks up against Core Web Vitals. Their study found that only 33% of sites on the web are passing Core Web Vitals.

data from Ahrefs tracked on a line chart finds that shows only 33% of sites on the web pass Google's Core Web VitalsFrom Ahrefs.
