What's interesting is eBay's participation in this. Yahoo and MSN have been eager to knock off Google, the #1 search engine, but until recently, there hasn't seemed to be animosity between Google and eBay. However, such entities as eBay Express and Froogle, and Google's promise of an online payment system to presumably rival PayPal, may have changed all that.

As an eBay seller, naturally my concern is about eBay results and so far the promises are exciting. It would be great to have my auction listings on Yahoo. But what about ''contextual ads'' on eBay?

According to eBay North America president Bill Cobb, " This will include testing some sponsored search ads for complementary products and services. For example, a buyer searching for a hair dryer might be presented with sponsored search ads for related items like shampoo or hair brushes. To be clear, we will not place ads on view item pages."

This can only strength the Yahoo Publisher Network program, and as a participant of that as well, I am excited about that. Competition among the giants will most likely result in good things for us small sellers.
