How many subdomains is too many? The impact on your SEO

Subdomains are a great way to organize and categorize the content or functionalities of a website. They allow you to create unique URLs for different sections of your website, which can help with SEO and user experience. However, is there such a thing as having too many subdomains?

Technically, a domain can contain as many as 500 subdomains. That’s a lot of subdomains! However, just because you can create that many, it doesn’t mean you should. Here are some things to consider:

  • Managing a large number of subdomains can become unwieldy and time-consuming.
  • Each subdomain requires its own SSL certificate, which can be costly and time-consuming to manage.
  • Search engines may view a large number of subdomains as spammy or manipulative, which could hurt your website’s search rankings.

    So, while there isn’t a hard-and-fast rule for how many subdomains are too many, it’s best to approach subdomain creation strategically. Consider the needs of your website and your users, and create subdomains that make sense for your content and functionality. In general, it’s better to have fewer subdomains that are well-organized and easy to manage than to have a large number of subdomains that are messy and chaotic.

  • Tips:
    1. Consolidate subdomains where possible: Instead of creating multiple subdomains for separate sections, consolidate them under one domain. This can help avoid the problem of having too many subdomains and improve the overall site structure.

    2. Consider the content: When deciding how many subdomains to create, consider the type of content that will be featured. If the content is related and serves a similar purpose, it may make sense to keep it all under one subdomain, instead of creating multiple ones.

    3. Use subdomains sparingly: While subdomains can be useful for organizing content, they should be used carefully. Avoid creating too many subdomains or ones that don’t serve a clear purpose, as this can negatively impact SEO.

    4. Keep it consistent: If you decide to use subdomains, try to keep the naming and organization consistent across all of them. This can help with brand recognition and make it easier for users to navigate your website.

    5. Monitor performance: Keep an eye on how well your subdomains are performing in terms of traffic and engagement. If certain subdomains aren’t performing well, you may want to reconsider their purpose or consolidate them with other sections.

    Defining subdomains and their limit

    A subdomain is a part of a larger domain, representing a different section or area of a website. For instance, a store section of a website can have subdomains such as,, etc. The subdomain names help users to navigate to the specific sections of the website they need quickly. However, too many subdomains can make it hard for users to remember them all and easily find relevant content. According to the Internet Engineering Task Force, the limit of subdomains in a domain is 127. While a domain can have up to 500 subdomains, too many subdomains can lead to technical issues and hurt SEO efforts.

    Advantages of creating subdomains

    Creating subdomains has several benefits, including better organization of website content, more control over site structure, and improved user experience. Subdomains can help to organize a website’s different sections into isolated areas, making it easier to manage and update each section separately. This flexibility also offers more control over the structure of the site, allowing for better customization of the user experience and making it easier for users to find relevant content. Subdomains can also help to boost SEO, since search engines recognize subdomains as separate websites, providing an opportunity to target specific keywords and improve overall SEO performance.

    Factors to consider before creating multiple subdomains

    While subdomains offer many advantages, creating too many can also result in some drawbacks. Before creating multiple subdomains, it’s essential to consider factors such as the size of the website, its structure and content, and the technical limitations of the website’s hosting environment. Creating subdomains that are too complicated, or too many of them, can make it confusing and challenging for users and search engines to navigate the site. Additionally, creating too many subdomains can lead to problems with website loading speed and affect the website’s overall performance.

    Effect of too many subdomains on SEO

    While subdomains can be beneficial for SEO, creating too many of them can have a negative impact. Search engines like Google prefer websites that are easy to crawl and index. Having too many subdomains can make it challenging for search engines to navigate and understand the site’s content, leading to lower rankings. Additionally, having too many subdomains can dilute the site’s authority and make it challenging to build backlinks. This can hurt the website’s overall organic search performance.

    Strategies to manage subdomains and their impacts

    To manage subdomains effectively, it’s crucial to maintain a good balance between website organization and user experience and SEO. Before creating subdomains, it’s necessary to evaluate the website’s content and structure to determine the best approach for organizing it. It’s also essential to consider the technical limitations of the website’s hosting environment and choose a hosting plan that can accommodate the necessary subdomains. Additionally, monitoring the website’s performance, including page load speed, organic search rankings, and engagement metrics, can help ensure that the subdomains are not negatively impacting the site’s SEO.

    Common mistakes to avoid while working with subdomains

    Some common mistakes to avoid when working with subdomains include creating too many subdomains, creating subdomains that are too complicated, or lacking direction, and not properly managing the subdomains. It’s essential to keep the subdomains organized and to the point to ensure that users can find what they’re looking for quickly. It’s also essential to choose simple and descriptive subdomains that are easy to remember. Additionally, it’s crucial to manage the subdomains well and ensure they are correctly set up with the right DNS or hosting configurations to avoid any technical issues. Avoiding these mistakes can help ensure that the subdomains are beneficial for both users and SEO performance.
