Hi, I started with Affiliate marketing about a week ago and I have just a couple basic questions. I've decided to focus on PPC marketing. I've read that it's better to have multi-page landing pages i.e. landing sites and that I should create one landing page for each ad group, if I create a Landing Site, does that mean that I can't promote only one product, or does it mean that I should simply add pages like a Contact us form and Privacy Policy, and regarding ad groups, lets say I create a campaign that contains 3 ad groups, does that mean that I should promote three different products or can I promote just one product. I hope that I haven't posted this in the wrong section.
