http://www.cb-analytics.com is a great website that gives detailed information about all products in cb. Have you used it when you start your promotion?
Nope. I just discovered it. The best research tool is to get out there and experiment. If a product doesn't sell, it doesn't sell.
Yes, I've been using it since it was launched. The graph helps me gage CB's tracking and sales. It's also informative to see product stats.
I use it all the time, this is how I pick out which products I intend to promote. If it is still climbing in gravity the market is still hot and I hop on the bandwagon.
It's very useful to know which product you should promote to make profits. Also, when you study the graphs carefully you will know when to stop promoting certain products. It's the best tool for clickbank affiliates.
That's why you use tools like cb-analytics instead of spending $100's on a so called "experiment". It will tell you if a product doesn't sell.
