I am working on a marketplace for which clients get constant proposals from service providers. The proposals usually include an image, description and price. A large number of the clients browse through the proposals list, but take no action regarding them. What could be appropriate ways to encourage clients to like/dislike the proposals?
For us taking an action is one step closer to the checkout funnel. Also Liking/disliking helps other service providers fine tune future proposals, allowing clients to being closer to receiving the perfect proposal.
