Thanks @EliasIT. I was thinking about @azb1's original post mentioning GoDaddy.
If you Google 'register domain name' or 'web hosting' there's already plenty of advertising, including GoDaddy themselves. It's going to be hard to compete in the AdWords auction, when you're getting a % of your competitor's profit.
Business Name Generator is an example of what I mean. Anything you do there ends up with a Godaddy referral link. Similarweb shows over 2 million visitors per month. Their keywords are a lot easier and they're not even paying Google for the traffic. That is smart referral marketing.
