I used to think this would inevitably be the case - go for something with proven track record, right?
However, I'm considering another strategy.
Maybe the biggest CB products are saturated, due to the "cumulative advantage theory". Imagine a new product, it might convert amazingly but because no affiliates have jumped on it yet, it has no gravity. And because it has no gravity, no affiliates will jump on it.
I'm having this feeling that there might be some "clickbank goldmines" out there and that if none of the other affiliates are all over it, you might have all the keywords to yourself etc.
Of course, setting up some PPC and measuring results is the way to go... but does anyone have any experience with this they would like to share with the Warriors?
