I noticed this morning that Google put a sponsored result into the suggested searches that populate when you start a search. The implications for this are the same as with Chrome: having the #1 spot in Adwords takes on a much greater role. But it also raises issues of people who are a bit click-happy, and of potentially wasting money. I was looking for operating hours of the Minneapolis Macy’s, and clicking on this would have been a cannibalization of natural results. This indicates the necessity of careful goal measurement in PPC.
