Subdomain Finder (2024)

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.

Regular domains are your standard URLs like splashthat.com or splashthat. events. Subdomains are a unique URL that lives on your purchased domain as an extension in front of your regular domain like support.splashthat.com or blockparty.splashthat.com.

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.

Subdomain Finder scans the DNS records and supplementary databases to analyze the domain's hierarchy. Our subdomain scanner checks: DNS records (NS, MX, TXT, AXFR) DNS enumeration. SSL certificates.

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.

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.

In the Domain Name System (DNS) hierarchy, a subdomain is a domain that is a part of another (main) domain. For example, if a domain offered an online store as part of their website example.com , it might use the subdomain shop.example.com .

Typically, subdomains are free through your web hosting provider. Domain registrars like GoDaddy and IONOS enable users to create subdomains at no additional cost. Some providers offer a free domain name in addition to free subdomains.

A Subdomain Can Compromise Your SEO Efforts

You don't want a subdomain on your website because it can compromise and harm your SEO efforts. If you're a small business with limited resources, you should make the most out of what you have. Creating a subdomain can waste your SEO budget and leave you with no results.

How do I find all subdomains in Google? ›

Google's search operators make it easy to narrow down the search to find more subdomains. We can use the "site" operator in the search bar to find all the subdomains that Google has indexed for a domain. Google also supports the minus operator to exclude any subdomains we are not interested in.

It is important to note that a subdomain and a subdirectory are not the same. 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.

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.

If you use public TLS certificates on your subdomains, they can be easily found through certificate transparency logs.
