Avoid Hyphens If Possible

What is the Difference Between Domain and Subdomain

If your domain name is two words , you may want to separate the words with a hyphen for readability: But, keep in mind that use of hyphens also strongly correlates with spammy behavior and decreases domain name readability and memorability. For that reason, generally, no more than one hyphen should be used .

What Is A Subdirectory

Finally, we have subdirectories, which are folders within the main domain, that is, categories within the website.

In the URL address, the category is positioned after the domain and extensions and is preceded by a slash symbol, as in the examples below:


Like subdomain, the subdirectory allows for separation according to different sections.

The big difference is about how Google identifies these pages. For search engines:

  • subdomains are separate identities from the website
  • subdirectories are seen as the same main domain.

Therefore, if the website already has a robust structure, the subdirectory will also have backlinks, traffic, and authority.

What Is A Wildcard Subdomain

A wildcard is basically a catch-all subdomain. It lets you create tons of subdomains without having to manually set up each one.

For example, if you wanted to create a WordPress multisite network, you could use a wildcard subdomain so that each network site can get its own subdomain .

A wildcard subdomain is represented by an asterisk. For example, *

Its An Ongoing Debate In The Seo World Between Subdomains And Subdirectories Which Is Better

Here, youll find:

  • The difference between subdomains and subdirectories
  • How each factors into your overall SEO
  • The difference in their URLs
  • Expert advice for deciding where to host your blog

When youre creating a marketing plan, some aspects are clear.

You should leverage organic and paid avenues, you should probably be on social media, and you should keep tabs on how your business presents online, from meta descriptions to customer reviews.

But then there are more hotly debated topics. How long should proper SEO take? Is it worth it to try to go viral on social media? Should you host your blog on a subdomain or a subdirectory?

Your time is valuable, so lets tackle that last question with help from one of HawkSEMs lead strategists, Yara Askar.

Whats The Difference Between A Subdomain And A Subdirectory

What Is a Subdomain? [Definition + Examples]

As Yara explains, a subdomain is a child domain of the root or parent directory domain. A subdirectory works like a root directory subfolder.

While a subdomain is a child domain, its treated as a separate entity from the main parent domain. The subdomain is still associated with the root directory. However, itll have a separate content strategy, analytics and tracking tools, and a different backend site.

Basically, any domain authority a root domain holds such as backlinks wont carry over to the subdomain. A subdirectory, on the other hand, lives within the root domain. It benefits from the root domain SEO equity and can add to the overall website SEO value.

Google doesnt technically favor one over the other when it comes to subdomains vs. subdirectories.

Subdomains Explained In More Detail

To answer the question of what are subdomains in more detail, you should first know about the anatomy of a URL! Let us examine the URL of ThemeIsle.

This URL contains two parts:

  • A protocol is a set of guidelines that a browser follows to send a request to the server.
  • The domain,, or URL to the main website. A domain consists of two parts:
  • the TLD which is the .com part , and
  • the SLD , themeisle, the name that you buy from a domain registrar.

A subdomain contains a second name before the SLD. For instance, if the Themeisle blog was hosted on, the blog would be the subdomain.

Restrict Subdomain Access To Addon Domains

Each Addon Domain requires a subdomain. Using mod_rewrite, you can stop people from using the addon domain as a subdomain of the primary domain.

Put this in the .htaccess file located at the subdomains folder, changing the subdomain,, and

RewriteEngine OnRewriteCond % ^$ RewriteCond % ^$ RewriteCond % ^$RewriteCond % ^/$RewriteRule ^$

What Is A Domain

To have a website that lives on the internet, youre going to need a domain name. Without a domain name, theres no way for visitors to access your website!

Before domain names were invented, you needed to type in the IP address for a given website to access it. Today, domain names act as a placeholder for the complex string of numbers known as an IP address. So, instead of typing in a series of numbers like you type in into your browser.

This makes things much easier and makes the consumer internet much more user-friendly.

When youre trying to find the perfect domain name, youll not only have to come up with the perfect domain name, but youll need to choose a domain extension as well.

This is the .com, .net, .org portion of a domain name. The domain name extension you choose will influence how your visitors perceive your domain, so choose wisely.

Does The Domain Extension Affect Seo

How Do Subdomains And Subdirectories Affect Blogs

Subdomains make perfect sense in some instances. For example, when a company has a niche industry, audience, or keyword they want to target thats different from their root or main targets.

This also applies if the subdomain is intended to represent a completely different business or division from the root domain, such as a SaaS company that also runs an online vendor marketplace.

In most cases, however, sites target the same audience with their blogs as they would with the root domain. Their content strategy is also likely intended to serve the same business. In that case, its best to host a blog as a subdirectory.

Hosting your blog as a subdirectory can allow you to:

  • Increase organic traffic to the root domain
  • Organize content in a way that makes it easy for bots to manage and crawl
  • Optimize the content on the site without having pages compete with each other
  • Streamline analytics by housing all metrics on a single domain

Subdomains can be useful for blogs if theres a large content campaign that is slated to receive a lot of traffic and thus requires its own hierarchy path.

Create A Separate Site For Mobile

A subdomain can also be utilized to provide a more mobile-friendly experience for your site visitors. Search engines like Google can recognize the type of device a searcher is using, and will serve the version of your website that gives them the best user experience. You can create separate versions of your website that cater to mobile, and even more specifically, to each screen size.

This adaptive approach gives users a unique experience, catered specifically to the type of device theyre currently using. Each of these different layouts have their own specific subdomain. Providing a mobile-friendly subdomain is a must in todays world, where more users are conducting searches on smartphones than on other devices.

What Is A Subdomain And How Does It Work

In spite of its low entry barrier, the internet is a mighty complex territory filled with technical jargon that at times may sound eerily similar to Klingon. Building a strong online presence starts in a fairly straightforward manner – simply create a website and purchase a domain name. However, things get more complicated once you want to grow your site, improve your performance and come across new terms such as subdomain.

If you know what is a domain, you may already have a general idea of what a subdomain is, based on the obviousness of its name.

Don’t Sweat Over Domain Age

The notion that the age of a domain is an important SEO ranking factor is a myth. When asked about domain registration length, Google’s Matt Cutts said, “To the best of my knowledge, no search engine has ever confirmed that they use length of registration as a factor in scoring. If a company is asserting that as a fact, that would be troubling. The primary reason to renew a domain would be if it’s your main domain, you plan to keep it for a while, or you’d prefer the convenience of renewing so that you don’t need to stress about your domain expiring.”

What does matter to Google are things like how long itâs been since your site was first crawled or since the first inbound link was recorded. Even so, though, Matt Cutts assures that “the difference between a domain that’s six months old and one year old is really not that big at all.”
