I focus a lot of my efforts on promoting physical product via affiliate links - Amazon and Commission Junction. All sales to date have been through meticulous keyword research, SEO and attracting free, highly targeted traffic. Conversions rock but commissions suck!
Is PPC a possibility for promoting products with such low Commissions?
Before you say test I am! Because my sites are so keyword focussed I get a consistent quality score of 10/10. However, is it ever possible to make these campaigns profitable? Search or Content Network?
