… Unless You’re an Advertiser
If you’re an advertiser, Google History, which I wrote about yesterday, is the best thing since, well, there is no “since” because never before has an advertiser been able to potentially know all someone’s media activity and target ads based on it.
Google History tracks not only your Google searches but also, if you let it, all your Web surfing activity. Imagine the power of being able to target someone based on exactly what sites they’ve visited — even to weight the ads after guaging their level of interest, based on the sites they visited, how much they surfed each one, even which pages they went to within those sites — perhaps even how many links they clicked or what they did.
Here’s a little look at my Google History for one short period of time.

I looked up some software plugins, a New York media group, and Niagara Falls (my wife wants to visit the region this summer). Already, you know a lot more about me than you did, and if you wanted to target me with an ad you’d have some darn good ideas of what might work.
