Yahoo is closing it’s doors for small publishers participating in the Yahoo! Publisher Network. The self-service beta program, known as Yahoo Publisher Network Online (YPNO), will be shut down on April 30, 2010. This will affect only small publishers while large, direct publishers and partners will continue to enjoy the service, Yahoo made it clear on a blog post.

Yahoo didn’t provide a specific reason for the shutdown of the YPNO, but said that after an “extensive review” it decided to shut the program down on April 30, 2010. In an e-mail sent to participating publishers, Yahoo said that it will pay publishers for the month ending April 30, 2010 no later than May 31, 2010.

So, Yahoo Publisher Network Beta game is finally over! What to do now? Don’t worry, there are many opportunities for small publishers like us.
