Pinterest aims to display a greater variety of content types in the home feed by utilizing a new ranking model.
Pinterest found itself with a problem of wanting to boost more content types while still keeping content recommendations relevant.
To solve this problem, Pinterest is introducing a real-time ranking system for its home feed called “controllable distribution.”
Controllable distribution makes it possible to specify a target for how many impressions a certain content type should receive.
For example, controllable distribution could be used to specify that 4% of users’ home feeds should contain video content.
