Choose a domain name that represents your business and the products      and services you offer

Domain names can be up to 63 characters, but try to create the shortest      domain name that is most recognizable to your audience

 Incorporate a popular keyword into your domain name

The easier your domain name is to pronounce, the easier it will be to      remember

Dashes work well if you want to create a domain name that is unavailable,      i.e. www.your-own-domain.com (they also show up higher in search engines)
