There are a few ways to peel the Adwords apple. I started with direct affiliate marketing (bypassing a landing page going directly to the affiliate website). Yesterday I made a landing page and am now directing traffic there.

Pros:
1. I can track links
2. I have adsense well-placed on the page
3. I have additional products in the family of items listed below the main item
4. I have a website offering other products people can click

Cons:
1. The landing page may not sell as well as the affiliate page
2. Extra click required to get to affiliate sell page
3. Requires website/webpage

Only time and testing will reveal how well this works. I already like the flexibility I have with the targeted traffic (tracking and additional sales opps).
