So I understand the traffic is targeted, but doesn't convert.
Surveys probably don't work (according to you).
Try to get their email addresses so you can build a mailing list.
From the "thank you for registering" page autoforward to the product page they originally were on. I do that on one of my sites with dhtml drop-ins, and it works.
If they don't buy on their first visit, you may later start selling to them via your list.
Advantages:
You build a reputation
You can mail them as often as you like with product information
You can even ask them for product they want to buy in the future or this holiday season
You can market exactly these products to them

Give it a try. Maybe it works for you as well.
