Why Buy a Generic Domain Name?
Generic is good
Internet users are attracted to generic domains. When a user performs a search, names based on the keywords they are looking for are immediately recognisable amongst the thousands of urls thrown at them every day. A generic name tells a user what your site's about before they get there. They know that you're just what they were looking for and they're primed for what you have to offer.
The sense of familiarity a user feels when they see a generic domain establishes a level of trust that encourages them to explore further, bringing their clicks and cash with them.
Shortcut to Success
Domains formed from keyphrases can capture type-in traffic - users who type the keywords they're searching for directly into the address bar of their browser, adding .com, .co.uk or another extension to the end. And if they type in the keywords in your domain, they'll go straight to your site. At no cost to you!
Think about that for a second. You know it's not easy getting high-quality, targeted traffic. Whichever market you're in, there are a lot of websites out there competing for the same pool of internet users.
Buy a keyphrase-based domain and you get free traffic... that actually wants to be there! You could slash your marketing budget to a fraction of what you originally estimated. No need to try every means possible to get people to remember you. When they think of your product, they'll think of you automatically!
