Google the Number No.1 Search Engine on the web and the largest Online Advertising Network too has recently announced to roll out new features to their advertisers and web users which would let them see Ads based on their interests. The New system would use Dart’s cookies to serve the ads to the user based on their interest. Advertisers also would have more options than ever they restrict the way their ads are displayed to a user, and it don’t appear to same user too frequently. Here is a snippet from official Google Blog introducing this new feature
We think we can make online advertising even more relevant and useful by using additional information about the websites people visit. Today we are launching “interest-based” advertising as a beta test on our partner sites and on YouTube. These ads will associate categories of interest — say sports, gardening, cars, pets — with your browser, based on the types of sites you visit and the pages you view. We may then use those interest categories to show you more relevant text and display ads.
This is very important step in the evolution of search! The era of keywords is almost over! Era of interest-based advertising just started.
People search the internet according their short or long term interests. Therefore all searches are just expression of these interests. Interests are the driving factor of search on the Internet.
For the list of top interests look at http://www.interestmatrix.com/top1000.php
The next step will be using cross-reference of interests. Like if you are already indicated interest in X you should be also interested in Y. See the site that has a list of practically all interests and cross-reference of them is http://www.interestmatrix.com
