Subdomain Finder (2025)

FAQs

Are subdomains searchable? ›

Yes, Google indexes and ranks subdomains separately from the main site. However, the SEO impact of subdomains may not be as significant as that of subdirectories, as they are considered separate entities.

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.

Subdomains can improve the on-site experience when used properly, boost your domain authority if you're linking between the two sites, and can help you better organize content.

A simple Google search can help you find this in a quick move. Enter the “site: your domain” into the search bar, and Google will find all pages on the website that have been indexed. It can also be helpful in displaying pages that are hidden or less accessible pages.

What is a Subdomain Finder? A Subdomain Finder is a tool that discovers and lists all subdomains associated with a primary domain. In addition to subdomains URLs, the tool provides general data on each one, including traffic forecasts, traffic share, the number of keywords, and more.

The short answer is yes, Google can and will index and rank subdomains unless you explicitly take steps to ensure they're excluded from its index. Google's entire business model is based on discovering content. The same goes for all search engines.

1 Answer. Yes, you own and control the entire namespace below the domain you purchase, because DNS is hierarchical. Creating mail.example.com and blog.example.com is just a matter of adding entries to the DNS zone that you control.

Google states that subdomains and subdirectories are both fine, but subdomains are crawled and tracked separately. Your subdomain will likely be on its own for SEO factors like link equity, and it probably won't pass link equity onto your main domain, either.

Subdomain cons

Technical complexity: Managing multiple subdomains can be more complex and time-consuming than managing a single domain, as each subdomain generally requires separate hosting, configuration, and maintenance.

Google will not penalize international websites that exist on separate subdomains if they have duplicate content.

How do I verify a sub domain? ›

Within Google Search console, navigate to Webmaster Central. Here you'll need to add the property (domain) you want to verify. Next, you can click the Manage Site button and Verify this site.

There are some subdomains that are defined for virtually every domain name, such as www, and others that are very common, like shop or mail. But by going through and trying a DNS query using `dig`, `nslookup`, or `host` for as many possible subdomains, you might find some hidden ones.

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.

Good Domain and Subdomain Names

For a great subdomain name, remember one thing: simplicity. Search engines see subdomains as distinct entities, but they should still have your brand name. Don't make subdomains confusing with fancy names. Keep it simple to make it easy to understand and follow.

Subdomains and Their Levels

If you have subdomains at different levels, you should choose multi-domain SSL. If you have a single domain and multiple subdomains at the same level, Wildcard SSL is best-suited.

First, think of a subdomain name that best fits the section of the site you're assigning. Common subdomains include blog, store, shop, support, help, and events. There's no need to overthink this — pick a name that succinctly describes this part of your site, and limit it to one word if you can.
