KnowEm.com was designed to help users (individuals and businesses) check for the availability of your usernames or brand names across multiple social media websites, as well as check if trademarked terms are being used without permission. This tool is an excellent way for you to check the use of the names you may have now, or may wish to develop later. KnowEm can be used free of charge, but they do offer premium services at a range of prices, which covers the security of your brand, product or username on up to 300 social networks.

Go to KnowEm.com and enter your brand name or the name you use (or would like to use) on social media networks. For example, we would type “HEROweb" into the search field. After clicking the "Search" button, the term can be checked against 550 popular social network, over 150 domain names, and the entire USPTO Trademark Database.

 

If your name is being used already, the tool gives you the chance to check out who is using it and how it is being used in case you need to do some damage control. It will also show you if a name is available for a particular site, and offers you the chance to create an account using your name on whatever site it is not already being used on.
