A subdomain is a subset of a primary domain in the structure of a website’s URL that helps organize and navigate different sections of the site. In terms of SEO, a subdomain can be used to separate distinct content areas or functions of a website (such as a blog or an online store) which can be beneficial for targeting specific keywords or audiences without creating an entirely new site.


A subdomain is a way to organize and structure websites by creating additional sections or categories within the main domain. It is added to the left of the main domain, separated by a dot, and is used to differentiate different parts of a website, such as blogs, forums, or language-specific content. Subdomains can help improve the user experience by making it easier to navigate and find specific information on a website. From an SEO perspective, subdomains can impact the overall performance of a website. They can be used strategically to target specific keywords or topics, potentially improving search engine rankings for those specific sections of the site. However, it is important to note that subdomains are treated by search engines as separate entities, so the overall SEO impact may vary depending on how they are implemented and utilized within a website.


1. Example 1:
A popular online retailer, such as Amazon, may use subdomains to categorize their products and services. For instance, they may have subdomains like books.amazon.com, electronics.amazon.com, and clothing.amazon.com to differentiate and organize their various product offerings. This not only helps customers easily navigate through the website but also helps search engines to better understand the different sections of the site, potentially improving SEO visibility for specific products and categories.

2. Example 2:
A large news website, like CNN, may use subdomains to separate different topics or regions. For instance, they may have subdomains like politics.cnn.com, business.cnn.com, and europe.cnn.com to provide a more focused user experience for their audience. By structuring their content in this way, they are able to target specific keywords and topics more effectively, leading to better search engine rankings for each subdomain.

Best practices

When it comes to optimizing your SEO efforts with subdomains, it is essential to keep in mind that search engines treat subdomains as separate entities from the main domain. Therefore, it is important to ensure that your subdomain is relevant to your main domain and does not dilute your overall SEO strategy. One best practice is to use subdomains for distinct purposes or sections of your website, such as a blog or an e-commerce platform, to maintain clarity and organization.

Additionally, it is important to regularly monitor and analyze the performance of your subdomains to ensure they are contributing positively to your overall SEO efforts. This can include tracking the traffic, engagement, and rankings of your subdomains, as well as conducting regular audits to identify any issues or opportunities for improvement. By following these best practices and guidelines, you can effectively leverage subdomains to enhance your SEO strategy and drive organic traffic to your website.
