How often do people use Google Product Search

[EricVallee34]

I was was reading Tom Critchlow's excellent blog on how to rank well for Google Product Search.  I'm trying to find out if there are stats on how often people use this feature in Google (since it is not listed on Google's main navigation).  I'm working with a customer who has b-2-b products and am trying to determine the value of adjusting his ecommerce pages to appear on Google Product Search.

I don't have a percentage but I read somewhere that nearly 1/2 of the "buyers" on Google look at shopping results.

I think that shopping is important.... and becoming even more important over time.

The down site for me is that to get good sales from that channel you have to be very competitive on price.
