I manage PPC for my company and I need to know what others experiences are with the Yahoo Display network. My mid-level account exec has explained to me all the ways the can target potential customers. I'm asking for any feedback from direct experience only please. Thanks for your help in advance.

Bing was supposed to be taking away market-share from Google but I don't see a lot of evidence of that.

if you are looking for branding it helps. for conversion... not much. maybe freebies stuff. and its expensive.

FYI, I'm speaking of the Yahoo Display Advertising outside of adCenter.
