Following its successful acquisition of Double Click, Google is selling the search engine marketing site of Double Click to avoid conflict of interest.

If a blog, in the official Google blog, it says:

It’s clear to us that we do not want to be in the search engine marketing business. Maintaining objectivity in both search and advertising is paramount to Google’s mission and core to the trust we ask from our users. For this reason, we plan to sell the Performics search marketing business to a third party. We believe this will allow us to maintain objectivity and the search marketing business to continue to grow and innovate and serve its customers.

Google went on further to say it has not yet found a buyer for the Performic.
