Search and E-commerce

It's been a busy few weeks in the world of search and e-commerce.

Amazon.com announced plans to spin off a subsidiary to invest and develop e-commerce search technologies.

That announcement came just days after Yahoo! rolled out a product search feature that lets users compare products by price and obtain information on shipping and handling, as well as product reviews.

And, earlier this week, Dealtime changed its name to Shopping.com as part of an attempt to establish itself in merging worlds of search and e-commerce.

Have any of you (e-tailers) had any success with using these types of tools to promote your products? If so, which ones do you find most valuable or worthwhile in terms of traffic and increased revenue? (Froogle, Shopping.com, etc.)

Or, do you find them too cost prohibitive (in cases of cost-per-click models) and just take your chances using metatags and keywords in your page code?

Sorry, I'm new to this forum, but I did find your post.

I've done a lot of studying on this exact subject for a couple of new features for our shopping cart product.

Based upon my research, Yahoo Shopping receives the largest number of visitors per month with approximately 16 million. The other shopping search engines receive less than 8 million each.

I haven't found any reports on Froogle. That's probably due to it being in beta still.

I haven't found any studies on the conversion rates for visitors from shopping search engines.

If you have found any information, I'd love to read it. Also, if you like I can forward you the document I found.
