I found lot of very low competition (easy to reach google top 3) keywords, with nice search results (10 000 - 1000 000 searches/month), but almost no relevant adsense ads, no products to sell, no relevant CPA offers etc... How to make money with these keywords???
If no one is selling to those keywords, there is a reason. You'd be better off modeling success instead of spinning your wheels trying to create a market where there is none.
