Do subdomains hurt SEO?

What is a Subdomain?

A subdomain is a type of domain that is part of a larger domain. It is a segment of the main domain that can be used to organize and navigate to different sections of the website. For example, the URL can have a subdomain such as “”. Subdomains allow companies to group content together, making it easier for visitors to find specific information.

Does a Subdomain Hurt SEO?

Whether a subdomain hurts SEO is dependent on how it is used. Generally, subdomains containing additional content can help to improve a website’s ranking in the search engine results pages (SERPS). However, if the subdomain contains identical, or nearly identical, content as the main domain, it can have a negative impact on SEO. Additionally, if the subdomain links to a page that has been flagged as spam, this could hurt SEO as well. Ultimately, how a subdomain affects SEO depends on how it is used.

How do I mitigate a subdomain takeover?

What is Subdomain Takeover?

Subdomain takeover is a type of attack in which an attacker is able to control a subdomain of a domain to which they do not legitimately belong. By taking over subdomains, an attacker can access and control confidential information, such as credentials, sensitive files and even access the main domain.

Preventive Measures to Mitigate Subdomain Takeover

1. Monitor Third-Party Services: Keep track of all third-party services that are linked to subdomains of your primary domain. If a third-party service is no longer in use, make sure to remove the DNS record mapping it to your subdomain.

2.Regularly Audit Subdomains: Periodically audit all the subdomains of your domain. Check whether any of the subdomains are pointing to an external domain or an inactive resource. The audit should also include a review of all the DNS records and the TXT records associated with the subdomains.

3. Use Automated Tools: There are various automated tools that can help you scan for any subdomain takeovers that could be occurring. These tools can also alert you when a subdomain is vulnerable to takeover and help you mitigate it.

4. Set Up Proper DNS Records: Make sure that all the DNS records for the subdomains are properly set up. Additionally, if you are using a service that requires a CNAME, make sure it is set up properly. If you do not have a CNAME record for the subdomain, your domain is vulnerable to takeover.

5. Monitor Certificate Transparency Logs: Certificate Transparency Logs contain all the SSL/TLS certificates issued for your domain, including subdomains. By monitoring these logs, you can detect if any subdomain of your domain is potentially vulnerable to takeover.


Subdomain takeover is a serious security issue that should not be taken lightly. By following the above steps, you can ensure that your domain is safe from subdomain takeovers.

Why do hackers target WordPress?

WordPress is Popular

WordPress is one of the most popular content management systems (CMS) in the world, powering millions of websites across the internet. Because of its widespread use, WordPress has become a major target for hackers, especially those looking to exploit its weaknesses and gain access to sensitive information.

Security Vulnerabilities

WordPress is open source software, which means that anyone can modify and use it without needing permission from the developers. However, this also means that hackers can take advantage of any security vulnerabilities that are present in the code. Some of these vulnerabilities can allow hackers to gain access to the server, install malicious software, steal sensitive data, and even take over the website.

Outdated Plugins

WordPress plugins are great for extending the functionality of a website, but they can also be a source of security vulnerabilities. This is because WordPress plugins often have to be updated to stay secure, but many people don’t keep their plugins and themes up-to-date. Outdated WordPress plugins are one of the most common vectors for hackers to attack, as they can exploit the weaknesses in the old versions and take control of the website.

Financial Gain

One of the main motivations for hackers to target WordPress websites is financial gain. They can do this by stealing credit card information, personal data, or other sensitive information. They can also use the website to host malicious software, or they can redirect visitors to malicious websites and collect ad revenue. Lastly, they can also use the website to launch attacks on other websites.
