If your purpose in buying a trademarked term as a domain name is to try to confuse people, you’re opening yourself up to having a complaint filed against you and having to give up the domain name. Even if you’re not trying to create confusion, you’re likely to face some legal challenges by buying trademarked terms in your domain name. To be safe, you can search for U.S. trademarks at www.uspto.gov and make sure no one owns a trademark on the name you are considering.
Make sure you always retain control of your domain name. There are hundreds of businesses hosting their websites with a web host they’re not happy with. Poor service, surprise invoices, unreliable uptime and email issues are just some of the common issues customers are facing today. What most of them want to do is vote with their feet and walk out the door and find another web hosting provider. They don’t go through with it, however, because moving all their domains to another host is a complete admin headache. Choose wisely from the get-go so you don’t become one of these customers.
Even if the term isn’t trademarked, don’t buy domains that are just a variation of another domain name. This means avoiding plurals if the singular is taken (mediatemple.net vs. mediatemples.net), hyphenating a phrase (media-temple.net), or adding “my” or some other preposition (mymediatemple.net). Alternately, you might consider buying these variations yourself and set them up so that if someone types one of the variations, they are redirected to your main site.
