The Google Blog announced that they will be adding personalized search results by default for any person signed in to their Google Account. That means if you use any one of the following Google services Gmail, Orkut, AdWords, AdSense, Groups, Alerts, and so on... you will automatically be shown search results tailored to your past searching history.There are two clear concerns here. The most obvious is the privacy concern, but that is for a different blog. The second concern is the search engine optimization area. How can one optimize a site for a search results environment that is constantly changing.
