So I searched for "Kanye West" on MSN, and look at the PPC ads in the screenshot (on Flickr, URL below). Page two of SERPS showed 4 ads with the "janet jackson" keyphrase?? It did happen to show one for the actual search term, "Kanye West". This happened twice, then the third time it seemed to show the correct PPC ads. I had not searched for janet jackson any time recently (or ever), so it could not have been a cache issue. Has anyone else seen this?
