Hey Guys, I am new to CPA Affiliate marketing, But i am planning to learn it at any cost. i am planning to sell products using bing PPC traffic. I have like 200 products list to promote and i am not sure what to start with. I need to do Keyword research on mainly 2 points. 1. Products having good traffic on bing. 2. Products having easy competition/low bid rate. Please suggest any tool ( Free if possible or a cheaper one ) to do this kind of analysis. Thanks in advance.
