‘write a review’, Holland’s largest online retailer, needs product reviews to help shoppers choose the right product. We doubled the completion rate of the review flow, by using a persuasive conversational interface.


The desired behavior

  1.  customers leave more reviews

  2. more click through rates in email

The result after applying behavior design



The techniques that worked best for this case

How we got to work

Bpost was involved in the co-creations of the new designs and took care of the front- and back-end. After the launch, we kept discussing the results of the new pages.

Research was conducted by us

2 co-creation sessions

Detailed mock-up designs were tested

What was the end result? and Buyerminds won the first Dutch CRO Award for this beautiful case. We are currently optimizing the conversation based on data of millions of customers.

The results we have:



  • The conversion rate doubled



“I found the philosophy of co-creating very interesting. This way you don’t get  the typical briefing thrown over the wall and a while later a design thrown  back. Collaboration is key.”
