How to choose a domain name

Don’t worry about choosing some snazzy brand name. Choose the country extension for your primary market (e.g. .co.uk) (don’t be tempted to create duplicate sites at different country extensions).

Choose a URL that contains your target keywords, and if necessary break it up with dashes. (See this post from Matt Cutts - Google does not penalise URLs with dashes).

Browsers are searching for their target product, not your brand name - give them what they want!
