Many of DNFix's accepted domain names will embody similar characteristics. Here are a handful of guidelines:
1. The extension matters. .Com is still king. .Net and .Org are next in line. ccTLD (international domains) are gaining incredible popularity
2. Shorter is better, so you'll see more 5-character domains than 25-character domains
3. One-word dictionary domains are great. Two words are OK, but they have to make sense together.
4. No dashes.
5. Numerals are discouraged, but there are obviously some exceptions like 247 (twenty-four-seven), 365, and 1800. Also, 2 or 3 character domains with numerals are not only fine, but are strongly encouraged.
6. Geo domains rock. If your domain starts with a large US or International City, State/Province, or Country Name, and ends with a legitimate product or service, there is a good chance it will be accepted to DNFix.
