Pinterest has introduced a new feature called Board Sticker
that helps drive traffic from Idea Pins. The company is currently testing the
feature with a limited number of users.
With Board Sticker, you could highlight a specific Pinterest
board via your Idea Pins. The option will enable selecting a board from existing
boards, as well as various display formats.
The sticker will eventually lead other users to your dedicated topic board, which in turn would make more of your Pin content stand out, hence driving more referral traffic from those links.
