I want to advertise my site using ppc from Google, Yahoo and Microsoft, but I've never done it. So, I'd like some help as to how to maximize my campaigns. I've heard many people use ppc for the first time end up wasting a lot of money, since they don't know how to implement their campaigns. Any help is greatly appreciated, thanks.
Here is a great resource site on how to start building your ad campaigns: http://www.ppchero.com/2007/12/16/catch-more-clicks-and-conversions-with-better-ad-text/
use long tail keywords to get cheaper clicks, also make use of the free $$ they give out to new members
