What, would you say, is the absolute minimum search results to even be worth trying a keyword or phrase? Disregard the competition for this comparison. I've found a few keywords with 500 - 1000 searches a month (global) for exact match that have very little competition. If I had #1 on Google, how many hits do you think I'd get a month? If monetized properly (let's say PPC and a few affiliate links), would it be worth the effort?
