I've used adwords for several of my CPA campaigns, and have been plagued by low quality scores. As soon as Adwords realizes that a page is a "bridge" page to another offer, they "Google Slap" it with a low quality score. How to get around this: Once you've created a profitable adwords campaign (your ad, landing page, and offer create a profitable channel), just keep changing the domain name that you use for your landing page. Google starts every new campaign (domain name) with a quality score of 7. Once your quality score falls to a 3 or lower and traffic dies, simply purchase a new domain name and hosting package for that domain name. It's a little more costly, but if you do it a couple times a month, some hosting companies will refund your money for the previous domain and hosting package if you cancel it within a given amount of time. It's hard to do CPA on Adwords with a "bridge" landing page, but if that's how your doing it, I've found success with this method of changing domain names. GOOD LUCK! Thanks is appreciated!
