Despite increasing traffic on one of my websites, Adsense CTR has been steadily decreasing for the past 2 months. I was getting an average 20% CTR in March. Yesterday, only 4%. Today, only 1%! What are they doing over there? It is too the point where I am going to have to remove adsense because it simply isn't converting anymore. The odd thing is, the ads appear targeted and are no different than what was being displayed 2 months ago. I fear they are manipulating the numbers to their advantage, or their tracking is simply inaccurate.
