Wave of Web

Today I received an email from Adsense about their new feature interest-based advertising. It sounds pretty cool. They are trying to serve ads on the basis of user interest. But how are they going to track individual interest? They will drop a cookie on the user’s browser when he clicks or views an Adsense ad in a site. This cookie will track his visits to that site & other sites. So it will know the trend of user & figure out a corresponding category to show ads that may interest the user. It’s pretty simple. you don’t have to change your ad code or account settings or anything. I am looking forward to it.

But as this DoubleClick DART cookie will store information from user, it requires a privacy policy to be implemented by the publisher.

By the way, you may opt out from  showing ads that are based on user interest categories. Still Google will use user’s previous interaction with the advertiser to show ads. But I doubt if it is a good idea not to try this new feature.

Here is more from Google about interest-based advertising. And check this out for information that you need to use in your privacy policy. Update privacy policy by April 8, 2009.
