Subdomain Finder (2024)

FAQs

How do I find a website subdomain? ›

By search engines

Search engines like Google supports various advanced search operators to refine search queries. These operators are often referred to as Google Dorks. We can use site: operator in Google search to find all the Subdomains that Google has found for a Domain. Lets take an example on “site:vulnweb.com”.

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.).

As long as you use them correctly, subdomains are fine for your SEO performance.

If all else fails, you can use Google search to find all the pages on a website. Simply type “site:example.com” (replace “example.com” with the website's URL) into Google's search bar, and it will return a list of all the pages on that site that Google has indexed.

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.

Yes, subdomain sites can rank well on Google if they are properly optimized for search engines and provide valuable and relevant content to users.

Google Dorking

Google Dorks are one of the best ways to find extenstive information about a target. 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.

However, Google treats subdomains as separate sites.

While “blog.example.com” and “example.com” may share a root domain, Googlebot will view them as distinct domains and crawl and index them accordingly.

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)

What does the subdomain tell you? ›

A subdomain is a prefix added to a domain name to separate a section of your website. Site owners primarily use subdomains to manage extensive sections that require their own content hierarchy, such as online stores, blogs, job boards or support platforms. Subdomains function as a separate website from its domain.

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.

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

A sitemap is a file of your site's pages, links and other information that helps Google read and index your site. Each subdomain has its own dedicated sitemap that needs to be submitted to Google individually. Tip: You can check your subdomain's sitemap in the address bar by adding /sitemap.

A subdomain is an extension of your domain that helps you organize content and expand your business offerings. It allows you to create standalone pages or functions, such as a blog or online store.

The domain is the highest level in the website address hierarchy. Subdomains are secondary domains that are part of the primary domain. For instance, in "blog.example.com," "blog" is the subdomain of the "example.com" domain. Subdomains allow you to divide sections of a website under the umbrella of the main domain.

It's quite easy to do so – all you have to do is create a CNAME record in your domain name system (DNS) records for the subdomain and point it at the desired destination URL. Creating a CNAME record in DNS is a general process, and the same basic steps can be used regardless of which hosting provider you're using.

Your subdomain site will essentially be its own entirely separate site, so you can set up navigation and themes however you want without affecting the site under the www domain.
