I'm working on a concept that would send traffic to a website to find an unknown product. It would require the user to browse through products based on hints to identify the unidentified product. The user would not be incentivized to make a purchase, and would browse at their own discretion. The user however would have a general interest in your product.
This concept is meant for ecom stores with 100+ products.
The value prop for you as a store is that this user, while not necessarily shopping for your products, would be forced to spend time on your site viewing products / marketing.
In my opinion the value of that user would be below display GDN (~$0.32 CPC), but significantly above CPM rates.
What is the value to you of a user with low intent (but some), but will spend a significant amount of time on your site?
