How well does it convert? What is the average of getting a sale after a certain amount of clicks? Do adwords allow you to put affiliate links in the ads? Thanks.
The main problem you will run into, are people using the same display url. You'll have to outbid those people to have your ad shown. I had to do this one which was a gamble at 5 bucks a click. Made a couple sales, but had a couple bad clicks which put me in the red. I think I could have done better at the slots.
Use a different url address. be creative. Don't go for the offers where everyone else is going. Those are the ones that work. Going for the most popular does not work. Need to create a good landing page and text.
Be creative. Use your own server and build landing pages or something. Take advantage of Adwords quality score and get the cost of clicks down to a minimum. Yes money can be made this way and many people are doing it. I am not though as I do not have time as I earn directly from my own sites and just use adwords to directly promote my sites as an whole.
