OK, Wisdom Dept:
I think I may have a knack for picking the right offers to promote. As a result, I don't have to try as many offers as I used to in order to find the winners.
For those still struggling, I say, be persistent. Keep putting up offers. And when you are ready to throw in the towel, put up still more offers.
If you've done that for a while, and are not having too much success, then it's time to...
Put up more offers.
I think you get the idea.
Now I use the term offers because I am primarily into CPA offers, but you can be successful with revenue share model as well. In fact I am moving my focus to rev share (product sale) campaigns more than I used to, because they tend to be more stable than CPA offers.
Hope this helps.
