What is URL to DOMAIN? is a professional tool that extracts and parses domains and subdomains from all kinds of URI schemes (eg. //, http://, ftp://, file://, ssl://, telnet://, and others). It does it in reverse too! It also allows to do other useful operations, including adding single quotes around strings, trimming URLs, generating a .htaccess deny file, and searching for specified keywords before generating final results. In addition, it can create a ready-to-upload 'bad backlinks' disavow file. For the best efficiency, it was built with the intention of automatic error correction of commonly malformed input values (supppressed depending on the chosen operation).

For whom is this tool designed?

For webmasters, online business owners, SEO (search engine optimization) professionals, web development service providers, copyright and intellectual property right owners, legal advisors, data research analysts, Internet marketers, and anyone else who hates spending hours trying to figure out MS Excel and related software.

It may be especially handy to site owners affected by a 'negative SEO attack' who plan to use the disavow tool offered by Google and Bing. The disavow tool allows webmasters to upload a .txt file containing a list of malicious / unwanted URLs or domains that link to the affected website in order to neutralize their potential negative effects and clean up website's link profile.

Where and how can I find suspicious links to create a disavow file?

The quickest (and free) way is to set up a Webmaster account with Google and Bing. Once you've done that, you can navigate to a page that shows links to your site and download/save the links file onto your local computer. The final step is to copy-paste the content of the downloaded file into the URLtoDOMAIN form above, select appropriate options, and create a disavow file.

Important - you should always manually review links pointed to your site before uploading a disavow file and include ONLY those that you think are unnatural or inappropriate. Otherwise, you may hurt your website's positive link profile and risk negative search engine ranking effects. If you are unsure which links to your site are inorganic and you haven't received a notification about unnatural or spam links in your Google / Bing Webmaster panel, our advice is not to upload a disavow file at all.

What kind of TLD and gTLD names does the tool use?

URLtoDOMAIN uses all ICANN domains and the majority of private domains. The database of names is regularly updated to make sure all TLD/gTLD names are valid and properly executed by the script.

Is there a limit on the number of URLs I can submit and analyze?

As long as you don't try to paste a million of URLs into the form at once, it should work without limits :) We strongly suggest not to include more than 500K of entries at a time to prevent service interruption (it may take up to several minutes for the script to finish execution of a large data set). If, after submitting the form, you don't see any results in a yellow-background textarea it means you tried to work on too many URLs at the same time.

What character encoding does the tool use?

All output data is encoded in UTF-8 format.

Can I save the results to a plain text (.txt) or a CSV (.csv) format file?

You surely can! The links to Open / Save the list of parsed sub/domains in a .txt or CSV format will appear on the Results page as soon as the extracting process is completed. For your convenience, the results will be available for download for several hours from the submission time and after that they will be automatically and permanently removed.

What is string search and how does it work?

String search allows to use four common search operations on input data. They must start with: #= as follows:

#=contains:STRING - it will find all lines containing full or part of the searched string

#=notcontains:STRING - it will find all lines not containing fill or part of the searched string

#=startswith:STRING - it will find all lines starting with the searched string

#=notstartswith:STRING - it will find all lines not starting with the searched string

#=endswith:STRING - it will find all lines ending with the searched string

#=notendswith:STRING - it will find all lines not ending with the searched string


- String search operation MUST be included in the first line of textarea.

- It is possible to use only one string search operation at a time.

- All searches are case-insensitive.

- There is no validation for wrong format or improper characters in the results (all input from textarea is included).

- All options, except for the ones from the OTHER OPTIONS section, will be ignored.

What are the two types of access to the tool?

The free limited version allows to work with up to 100 URLs at a time; the allowable input and output numbers are randomly-generated to avoid abuse of the limited version. For an accurate and confusion-free testing of the free version, we advise that your data input doesn't exceed 20 URLs at a time. You may click on the 'Test URLs' button to play with pre-defined sample links or add your own.

The unlimited version is activated and ready to use immediately after purchase. It has no usage and no input/output limits, and it automatically expires after the chosen period of time. The precise expiration date of the unlimited version will be shown right below the form.

NOTE: The unlimited version of the tool relies on a browser cookie for authentication purposes, so it must be accessed from the same web browser and the same computer from which the payment was made. Deleting or modifying a cookie associated with (the name of the cookie is: "UTD") will reset the access type back to the free version. If you want to access the unlimited version from more than one computer, you need to purchase separate subscriptions for each computer.

There may be similar domain extracting and create-a-disavow-file services available. Why should I pay extra to use your tool without limits?

It is the fact that links often contain identifiable or sensitive information. If you are a professional working on data collected by yourself, your associates, or your clients, it may be vitally important to protect this data from theft, unauthorized use, and malicious activities.

The following table explains the most important reasons for choosing URLtoDOMAIN (UTD) over our 'totally free' competition:

Secure - SSL data transmission and data masking; submitted data automatically and permanently removed
Powerful - executes thousands of URLs at a time; supports different protocols and hostnames; extracts/trims URLs; searches
