Subdomain Finder (2024)

FAQs

How do I find a list of subdomains? ›

A Subdomain Finder is a subdomain enumeration tool that helps you discover subdomain hosts (aka subdomain FQDNs) which serve specific functions for your target (e.g. hosting public websites, private subdomains for testing web apps, URLs where you can find backups, etc.).

Subdomains aren't directly bad for SEO, but they're not always the most strategic choice.

You can usually locate it in the root or footer section of the website. For example, the XML sitemap URL could be “www.example.com/sitemap.xml“. Once you click on the sitemap, you will find all pages & subpages of a website. You can use different sitemap generation tools if you don't have an existing sitemap.

If Google does not come across links to your subdomain when it's crawling your site or another site, then it won't be able to find your subdomain and thus won't index it. The only exceptions to this would be if: You submit the XML sitemap for your subdomain to Google via Google Search Console.

Let's say you are making a pitch to a client to create their new website. You can create a subdomain that is specifically intended for them to give an idea of what their new website might look like. This is hosted on your own main domain, while retaining ownership of the subdomain.

While a subdomain will appear before your TLD, a subdirectory link will include the subdirectory name after the original TLD. For example: Subdomain example: mysubdomain.mywebsite.com. Subdirectory example: mywebsite.com/mysubdirectory.

To test a new website

This is the most common reason why users create subdomains. Website developers might create subdomains as a testing or staging version of a website before it goes live.

People use subdomains for things like blogs, country-specific locations, or any time it feels like there are substantial resources on a topic, and they don't want to build out the main site. One example would be a help center like support.google.com. In all cases, subdomains help to organize the content by theme.

Does Google index subdomains? ›

Google treats subdomains and URLs differently when indexing websites: Subdomains: Google may consider subdomains as separate entities, each with its own ranking potential and SEO factors. They can be treated as distinct websites. URLs: Individual URLs within a domain are typically treated as part of the same website.

Default subdomain www is used by 39.9% of all the websites.

One of the disadvantages of opting for the subdomain option is that because the search engines view them as separate sites, they are treated as separate domains when it comes to determining rankings. Considerations need to be made for developing a subdomain into its own entity.

Yes, you should create separate XML sitemaps for each domain and subdomain. Each sitemap should list the URLs that are specific to that particular domain or subdomain to ensure search engines can crawl and index your content effectively.

A domain can have up to 500 subdomains. You can create multiple levels of subdomains such as store.product.yoursite.com, test.forum.yoursite.com, etc. Each subdomain can be up to 255 characters long, but for multi level subdomains, each level can only be 63 characters long.

Using a terminal and the command nslookup is the most effective way to search a domain's DNS records. On almost all operating systems, this command works perfectly and displays all DNS records for the domain. To show how to use the command, here's a sample nslookup command for each record type.

Find Subdomains of a Domain with NsLookup:

Replace “example.com” with the domain name you are interested in. This command will return a list of the authoritative name servers for the domain, which can often include the subdomains.

In Google Analytics 4, users can be tracked cross-subdomains without the need for additional code. It should generally be handled using the same measurement ID and leveraging reporting, comparisons, and segments to address different subdomain data views.

Each domain name can have up to 500 subdomains. You can also add multiple levels of subdomains, such as info.blog.yoursite.com. A subdomain can be up to 255 characters long, but if you have multiple levels in your subdomain, each level can only be 63 characters long.
