In a deal announced earlier today, Yahoo and eBay are teaming up around advertising, e-commerce, and search. Yahoo becomes the exclusive provider of graphical ads on eBay, and will also provide some text ads. They are going to make a co-branded toolbar, and they’ll work to make their respective VoIP apps work together (Yahoo Messenger and Skype). The biggest thing of all though, at least as far as I am concerned, is Yahoo’s adoption of PayPal:
Yahoo will make eBay’s PayPal service the exclusive third-party provider of its online wallet, allowing customers to pay for Yahoo services from bank accounts, credit cards or balances associated with their PayPal accounts. PayPal will also be integrated into product offerings for Yahoo merchants and publishers, including the Yahoo Publisher Network, Yahoo Search Marketing and Yahoo Merchant Solutions.
Yahoo using PayPal essentially removes any doubt that PayPal is the de facto payment service on the Internet. It will be very hard for Google to successfully introduce a competitor now. Two of the largest sites on the net in Yahoo and eBay, plus the millions of other smaller e-commerce sites all using PayPal is an enormous hurdle for any rival payment service. PayPal is the closest thing we have to a truly digital wallet. Incredibly smart move by Yahoo, and excellent outcome for eBay.
