i think keywords matters.... i wrote first time my own article on hard drive data recovery and got this click.
Tools like http://www.Spyfu.com and https://adwords.google.com/select/TrafficEstimatorSandbox can show you the average cost per click for different keywords. So use that to find what kind of keywords are profitable.
