Many of us involved in the web presence industry are challenged to create good domain names that are fit to cover all the issues of a good name and the added challenge of finding a .com available. We, at Image Factory ( www.webimagefactory.com ) named most of our clients' web sites, and we face this challenge on a daily basis. I am not a big fan of gibberish domain names, but many of our clients insist for a short domain name and the availability pool narrows by the second even for nonsense "words".
When searching for a new domain name, what criteria has proven best for you?
a) easy to market?
b) easy to remember?
c) search engine friendly?
d) branding-ready resonance?
e) most illustrative for the business?

How do you create a domain name?
1) A domain name identical or as close as possible to the name of the business the web site would represent?
2) Just the initials of the business, if available?
3) A domain name as short as possible, even if the only available short domain name would be a random mix of letters and/or numbers without a meaning?
4) A rhyming, jingle-like domain name, that would be easy to remember even if it is many letters long?
5) An invented, non existing word that resembles a meaning related to the business the web site represents?
6) A scrabble-like playful or humorous anagram?
