AWA,

I considered that possibility too. I am not an Oprah fan, but I read the news daly and have not seen anything in relation to the keyword.
Also, if that was the case, would not the CTR remain roughly the same as well? THat did not happen.
Also, the spike happened this morning. I had about 2600 impressions by 9 (Pacific time) and then it slowed to the more or less usual rate.
