How do customers typically become "aware" of a product. Before I heard of clickbank I had no way of knowing what products were out there. The reason I ask is because I get sales from "product name" not some generic long tail keyword. Do vendors promote their products elsewhere like on face book or something? Also is there some kind of timeframe near a products conception when sales increase and then die off? The second my site started ranking I was getting about a sale every other day for about 2 weeks. Now I havent gotten a single sale in 2 weeks. The same trend has happened with another site I had. There is no consistency in this area of income.
