METHODS AND SYSTEMS FOR SURFACING CONTENT ITEMS BASED ON IMPRESSION DISCOUNTING

---

Abstract

---

Systems and methods for surfacing content items to a user based on an impression discount are described. For example, an impression discount for a content item is determined. The impression discount may be determined based on a number of times the content item has been surfaced to a user. A selection score for the content item is updated based on the impression discount. The content item is selected from a plurality of content items based on a comparison of the selection score for the content item and selection scores for each of the plurality of content items. The selected content item is then surfaced to a client device corresponding to the user.
