Do a search on peppermint or Christmas at Google and look at those AdWords ads on the right. Can you believe that they highlighted them with a peppermint candy cane looking bar! I bet the AdWords customers are loving it and the organic fellows are a bit upset. Now, if you do a search on candy cane not only do you get those bars, you get the top AdWords ads with a redish background! Not only that, they covered hanukkah with hanukkah candles and kwanzaa with kwanzaa candles.
Only a little discussion on if this is evil or not at WebmasterWorld forums. I also posted a thread on this topic at Search Engine Watch Forums and our Search Engine Roundtable Forums.
