Yahoo and PayPal have launched a new program to promote the use of PayPal's Express Checkout, reports Search Engine Land.

Advertisers using both Yahoo's Sponsored Search Results and PayPal's Express Checkout service will now have a shopping cart icon displayed next to those sponsored results. Clicking on the cart icon will take visitors directly to a page where they can make a purchase. More information can be found here.
The shopping cart icon resembles the one used by Google for its Google Checkout option. But Yahoo SVP Rich Riley says that Yahoo's 100 million-plus customer base is vastly greater than the number of Google advertisers using that system.
