Is there a way to find all subdomains? ›

Subdomain Finder is a useful tool to help discover website subdomains. They can be used for a variety of purposes, including website reconnaissance, #vulnerability assessment, and #penetration testing. In this blog, let's discuss the top 10 subdomain search tools that can help you discover subdomains.

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

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.

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.

Create subdomains for specific users or clients

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.

A subdomain name is a piece of additional information added to the beginning of a website's domain name. It allows websites to separate and organize content for a specific function — such as a blog or an online store — from the rest of your website.

The most common subdomain is “www” or “world wide web.” The subdirectory points users to the main directory of a website—in other words, where your homepage and other core pages live. Other subdomains work to create distinct parts of a site. For example, Google's root domain is www.google.com.

How do I search for 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.

subfinder is a subdomain enumeration tool written in the Go programming language. Subfinder is used for discovering passive subdomains of websites by using digital sources like Censys, Chaos, Recon. dev, Shodan, Spyse, Virustotal, and many other passive online sources.

There are two disadvantages: A subdomain works like a separate domain in terms of authority: you would have to spend more time and money for building the authority for your root domain compared to when the blog was under a /subdirectory/ or on /separate-pages/.

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 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.

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.

While Nmap is primarily used for network mapping, it can also be used for subdomain hunting. Nmap uses various techniques, such as port scanning, to identify active subdomains and gather information about them.
