Saw this article this morning...I don't know the "in's and out's" of accomplishing this, but it would be great I would think!! Your thoughts??
Online marketplace Bonanza.com is sending a feed of its merchants' product-listings to Microsoft's Bing Shopping engine for greater visibility, and the site reports traffic and sales are up, with September being the busiest traffic month to date.
Sellers do not need to proactively do anything for listings to be included in Bing. However, they should know that Bing only accepts items in new condition.
