Hi. I've recently starting selling my website's products on Yahoo Shopping through Yahoo's Product Submit pay per click service. So far I've been less than impressed with the results, especially in terms of the quality of the traffic I seem to be getting from them. Has anyone else reading this tried Product Submit and had a similar experience with it? Also, could anyone recommend any services that are comparable to Product Submit but provide higher quality traffic? By "comparable," by the way, I mean a ppc search engine in which you bid on a category, not individual search terms as in Overture and Google Adwords. Thanks in advance.
