Actually I want to promote a clickbank product by article. But for this article I need a long tail keyword. This keyword will help me to get traffic. For this process, I was thought first I need to choose clickbank product. Here I am confused that how I'll choose a good product? Because in every product has "Stats". This Stats are talking about product strategy. So how can I know that exact meaning of "Stats" and from this "Stats" how can I distinguish the good product? After that I want to find a long trail keyword from this product. So how can I find a keyword(s) from this product? Because from these keywords will be helpful to find a long trail keyword by using "Google Keyword Tools".
