I've purchased Ultimate Niche Finder, ScrapeBox, Tweet Adder, and proxies. I am ready to start making money with ad sense. My plan is to setup one ad sense wordpress site per week. My questions are: Are there any other tools that I should purchase? How many monthly searches should a keyword get before I pursue it? I've seen some keywords with really high cpc that only get 50 searches per month, is that amount of volume too low? How many articles should each site have? I am planning on buying them through fiverr.
