A few months ago eBay formed a partnership with Yahoo! for providing advertising services for its US customers.
Now they have a partnership with Google for its international customers. This inspite of Google Base being a direct threat to its core business.
As a result of this deal, eBay customers would get access to stuff being sold on its auction site and to other vendors with offering that fit their needs. While this may benefit buyers, sellers on eBay may not be thrilled with having to deal with new competitors. The key question for eBay (given their new pricing models for listing) is if this would a net revenue plus scenario. In the same
announcement, Google and eBay are planning to test their pay-per-call advertising technology. This allows buyers and sellers to use either Skype or Google Talk to communicate directly.
