Pinterest introduced modules to improve the relevance of the Homefeed by providing more context and exploring new topics for users.Modules come in two types: landing page modules that take users to a separate page, and carousel modules showing a collection of Pins.To prevent user fatigue, a fatiguing approach stops showing a module if a user repeatedly ignores it.Module ranking involves ranking modules based on user engagement, with a dedicated model optimizing module actions like taps and clicks.A sampling strategy balances positive engagement labels and selected features for module ranking.Calibration and blending layers further enhance the module relevance, dynamically placing modules alongside Pins in the Homefeed.The 'skip slot' blending approach ensures modules are placed in feed slots based on surrounding Pin engagement.Future plans include improving relevance through real-time monitoring, magnitude-based ranking, and Pin displacement blending.The module relevance work on Homefeed was accomplished with the collaboration of various teams, as acknowledged in the article.Pinterest continues to focus on enhancing module relevance on the Homefeed to optimize user experience and engagement.
