I've recently been accepted to a CPA network and want to start out on the right track. I was considering jut doing direct linking, but in reading posts i've decided to start right out of the gate with landing pages. I've searched this forum and haven't been able to find any really good info on landing pages. Does anyone have any advice on what type of information they should include? Also, any examples would be greatly appreciated. I'm looking at using PPC to drive traffic to the LP.
