Google launches targeted advertising system
US computer technology giant Google on Wednesday launched a test version of a new "interest-based advertising" system for its network of websites including YouTube, the company said in a statement.
The new system is designed to record the interests of users based on the pages they view and Internet searches they conduct, offering tailor-made advertising offers to match which can then be further refined by the user.
"Keyword advertising has been so successful because it's useful to users, advertisers and publishers -- everyone's interests are aligned," Google said.
"We believe that interest-based ads will create the same virtuous cycle, by giving users more relevant ads, while generating higher returns for advertisers and publishers," it added.
Google said it would ensure transparency and user choice in the new system.
