I have just removed Adsense from my left sidebar because the performance has been truly awful. I installed it after a commenter came on pretty heavy with some bullish forecasts of how much money I was leaving on the table, and so I thought I should try it (as a reminder all money generated by this blog goes to charity).
The result – sub $10 in revenue over three and a half months.
The reason – nobody clicks through.
The explanation – people visit the EquityKicker to read and comment, I bet most of them don’t even notice the ad is there.
