CPC & CPA are most appropriate and effective form of advertising on small sites. If its targeted, you will make money. Simple.
How effective a banner is, has nothing to do with the amount of traffic you recieve.
You can get a 100 page views a day with 2 clicks. And that would be more effective then a 50,000/day page view site getting 500 clicks per day. Does it make you more money? NO, of course not.
But the CTR % is alot greater. And as your traffic increases, your sales will reflect it.
worthless in that they end up taking your hard-won visitors away from you own web-site!
I disagree. In most cases, yes. But this site provides an expensive service for free. That will keep myself, and the rest of the regulars continually coming here, reguardless of what ad solution Dan decides to use. (Unless it is pop-ups)
