Identifying content to present to a group of online system users based on user actions and specified by a third-party system
An online system receives information describing a target group of online system users from a third party system that includes one or more user properties, which may identify an action performed by a an online user within a time interval to include the user in the target group. When an opportunity to present advertisement requests to a user is identified, the online system retrieves actions associated with the user and times associated with the actions. If an action associated with the user matches the action identified by the user properties and occurred within the time interval identified by the user properties, and other characteristics of the user satisfy at least a threshold number of the user properties, the online system includes the user in the target group. Advertisement requests having targeting criteria, including the target group, satisfied by characteristics of the user are evaluated for presentation to the user.

a processor; and
a memory storing instructions that, when executed by a processor, cause the processor to:
receive tracking pixel data corresponding to a plurality of actions performed by a first user of an online system on a third-party site, wherein each action performed by the first user is recorded by a tracking pixel embedded on the third-party site and has a timestamp indicating when the action was performed;
add a first user profile of the first user to a first target group in response to identifying that a first action of the first user in the tracking pixel data satisfies a user property of the first target group, wherein the user property of the first target group defines eligibility for inclusion in the first target group, comprising a target action and a predetermined time interval associated with the target action, and wherein the first action of the first user satisfies the target action of the first target group and the timestamp associated with the first action is within the predetermined time interval associated with the target action;
identify an opportunity to present content items to the first user of the online system;
identify candidate content requests from a first set of content requests directed to the first target group, wherein the candidate content requests comprise a threshold number of targeting criteria satisfied by characteristics in the first user profile of the first user;

wherein the instructions cause the processor to:
in response to the first user has not interacted with the first content item presented on the client device of the first user, select a second content item having a lower position in the hierarchy of content with which the first user had previously interacted; and
present the second content item on the client device of the first user.
