I am seeing interest based ads on my site for the first time. I had suspected that this was happening ever since my ctr crashed in half months ago but I personally had never seen interest based ads on my site. I just spent a few minutes visiting some stock investing websites and now adsense is displaying ads for "stock investing reports" on my site. My site has absolutely nothing to do with investing. I can see how something like this can kill a site's CTR. Maybe they should call these, "contextual untargetd ads".
