Seems like since about a week ago I started earning about 5X more per click. But I also noticed less clicks. I also saw less targeted ads to my site. My conclusion: Because I am receiving different types of ads (not-related ones) I am receiving less clicks, but the new ads coming in are worth more money. Has anyone else been having anything similar.
I've noticed a change in ads too, less targeted even though no content has changed. Can't say i've seen a change in click value. Not all bad if your earning more though.
