Root Domain Vs Sub Domain: The Difference with Examples

Are you confused about the difference between a root domain and a subdomain? Do you want to know which one is more beneficial for your website’s SEO?

Well, you’ve come to the right place. In this article, we will delve into the world of root domains and subdomains, exploring their differences and highlighting the advantages they offer. So let’s get started and unravel this intriguing topic!

What is a Root Domain?

To put it simply, a root domain (or parent domain) is the main domain or the primary address of your website. It represents the overall identity of your online presence and plays a crucial role in how search engines like Google perceive and rank your website. For example, in the URL “,” “” is the root domain.

It serves as the foundation for all subdomains and subsequent URLs within a website. The root domain is denoted by the suffix at the end of a website’s URL, such as “.com,” “.org,” or “.net.” These TLDs categorize websites based on their purpose or geographic location.

For instance, “.com” typically represents commercial entities, while “.org” signifies non-profit organizations. As a professional, comprehending the role of a root domain empowers you to navigate the digital landscape with confidence, ensuring efficient website management and optimization.

Importance & Benefits of Root Domains

Having a strong and authoritative root domain is vital for your website’s SEO. Search engines consider the root domain as a trusted source of information and value its credibility. Here are some key benefits of having a solid root domain:

  • SEO Authority: A well-established root domain helps build SEO authority for your website, resulting in better rankings on search engine results pages (SERPs). This can lead to increased visibility and organic traffic.
  • Brand Recognition: A memorable root domain name can help create brand recognition and establish your online presence. This can contribute to improved user engagement and loyalty.
  • Link Building: Root domains are essential for link building strategies. When other websites link back to your root domain, it signals to search engines that your website is reputable and trustworthy, improving your SEO efforts.

Root domains provide consistency and trust to both search engines and users navigating through the websites. They convey a sense of stability and reliability, which can positively impact your website’s overall performance.

What is a Subdomain?

Now that we’ve covered the concept of root domains let’s move on to subdomains. A subdomain is a part of the main root domain that acts as a separate entity from the main website. It is created by adding a prefix before the root domain. For instance, in the URL “,” “blog” is the subdomain.

By assigning a unique subdomain to each section, users can easily navigate to specific areas of interest. For example, a popular e-commerce site may have subdomains such as “” for its online store and “” for its company blog.

This organizational structure allows for better management and enhanced user experience. Additionally, subdomains offer the flexibility to customize different sections for specific purposes, such as targeting different geographical regions or creating separate online communities.

How Subdomains are Used

Subdomains offer a great way to organize and manage different sections or categories of your website. They can be used to create separate websites, blogs, or even e-commerce stores that are related to the main root domain. Some common uses of subdomains include:

  • Blogs: Many websites have a dedicated subdomain for their blog section. This allows them to maintain a separate platform for publishing content and engaging with their audience.
  • E-commerce Stores: If you run an online store, having a subdomain for your store can help separate it from the main website. This allows for specialized management and customization of the e-commerce platform.
  • Multilingual Websites: Subdomains can be utilized to provide versions of your website in different languages. This helps cater to a global audience and enhances user experience.

Subdomains are commonly used for testing new designs, features, or experimental projects without affecting the main website’s functionality and user experience.

Root Domain Vs Sub Domain: Which One is Better for SEO?

The question of whether a root domain or a subdomain is better for SEO doesn’t have a straightforward answer. It ultimately depends on your specific goals and requirements. However, here are some factors to consider:

  • Root Domain SEO: A strong root domain can consolidate SEO efforts, as all subdomains benefit from the authority and credibility of the main website. This cohesion can result in better overall SEO performance.
  • Subdomain SEO: Subdomains allow for targeted SEO strategies for specific sections of your website. By optimizing each subdomain separately, you can attain higher rankings for specific keywords or topics.
  • User Experience: Depending on the nature of your website, subdomains can enhance user experience by providing intuitive navigation and categorization. This can lead to higher engagement and conversions.

Subdomains require separate maintenance and management, which can be challenging if you have limited resources. Root domains, on the other hand, offer centralized control and easier maintenance. At the end of the day, it’s essential to evaluate your website’s structure, goals, and user experience requirements to determine whether a root domain or a subdomain is the right fit for your SEO strategy.

What are the 3 types of domain name?

In the vast digital landscape, domain names play a pivotal role in establishing an online presence. Knowing the differences between these three types of domain names is crucial when choosing the most suitable online identity for your professional endeavors.

There are three main types of domain names:

  • generic top-level domains (gTLDs)
  • country-code top-level domains (ccTLDs),
  • sponsored top-level domains (sTLDs).

The first category, gTLDs, encompasses widely recognizable extensions like .com, .org, and .net. These are widely used by organizations, individuals, and businesses across various industries. Next, ccTLDs are country-specific extensions such as .us, .uk, or .de, and are primarily used by entities operating within a particular country or region.

Lastly, sTLDs are domain extensions that are managed or operated by specific organizations, often associated with a particular industry or interest. Examples include .gov for government agencies and .edu for educational institutions.


Understanding the difference between a root domain and a subdomain is crucial for optimizing your website’s SEO performance. While root domains offer authority, trust, and brand recognition, subdomains provide flexibility and targeted optimization.

Ultimately, the choice between the two depends on your specific needs and goals. So take your time, analyze your website’s structure, and make an informed decision to maximize your website’s potential.
