A subdomain is a subsection of a primary domain, used to organize and navigate to different sections of a website. It precedes the main domain name and is separated by a period. For example, in ‘’, ‘blog’ is the subdomain of the ‘’ primary domain.

Usage in SEO:

Subdomains can be used to segment different areas of a site, such as product categories, regional versions, or different content types like blogs or forums. While a subdomain is part of the main domain, search engines often treat it as a separate entity, which means it can have its own distinct set of content, keywords, and SEO strategies.


Utilizing subdomains allows webmasters to organize their content more effectively and can make a site easier for users to navigate. They can also be beneficial for targeting specific keywords or market niches without the need for creating an entirely new website.


Subdomains can be seen as separate entities by search engines, so it’s essential to provide clear, distinct, and relevant content that stands on its own merit. Link equity is not typically shared between subdomains and the main domain, so SEO strategies may need to be executed independently for each subdomain to improve their individual search rankings.

Best practices:

When using subdomains for SEO, ensure they have a clear purpose and contain high-quality content. Optimizing subdomain-specific meta tags, headers, and content can reinforce the subdomain’s topic and keywords. Additionally, building a robust internal linking structure between the subdomain and the main domain can help distribute link authority and improve the overall domain’s SEO performance.


When creating a subdomain, it should align with the primary domain’s overall branding and support the user experience. Proper implementation includes setting up a unique and logical URL structure, consistent navigation, and ensuring that the subdomain is included in your sitemap. Monitor and track the subdomain’s performance independently in your analytics and SEO tools to understand its impact and make necessary adjustments.

How should subdomains be optimized for SEO performance?

To optimize subdomains for SEO, ensure they have clear purposes and contain high-quality, relevant content. Implement subdomain-specific meta tags, headers, and content optimizations. Establish a strong internal linking structure between subdomains and the main domain to enhance SEO performance.
