I spoke to Adsense yesterday. She couldn't really tell me much that I didn't already know. She did say CTR is down a "little" this year. But my experience is that it has dropped by 1% this year. That's a significant drop.
Yesterday I was seeing quit smoking ads on my pet site. I haven't smoked in years, nor have I visited or searched for info on quitting smoking.
