The PubMatic Publisher Challenge is open to publishers of all sizes and geographies.

The advertising will be displayed on leading web 2.0 web sites that reach hundreds of thousands of unique users per month. The contest will be held on an ongoing basis.

"In just two months, over 1300 publishers are seeing the benefits of PubMatic, including increased ad revenues and less management hassle," said Rajeev Goel, Co-Founder and General Manager of PubMatic. "Our publishers' success is our own success, so what better way to tell the PubMatic story than through the voice of our customers."

PubMatic automates and optimizes decision making for publishers by identifying and recommending appropriate ad networks for a publisher and improving the layout of text ads.
