Content item selection

A computing device comprising:

• a processor;
• and
• memory comprising processor-executable instructions that when executed by the processor cause performance of operations, the operations comprising:
• detecting a first content event, associated with a first content item, performed by a first client device associated with a first user profile, wherein the first content item is associated with a first entity;
• detecting a first conversion event, associated with the first entity, performed by a second client device associated with the first user profile;
• determining, based upon the first content event and the first conversion event, a first duration of time between the first content event and the first conversion event;
• determining, based upon the first duration of time, a first attribution score associated with the first content event;
• storing a first plurality of attribution scores, comprising the first attribution score, in a first attribution data structure associated with the first content item, wherein an attribution score of the first plurality of attribution scores is associated with a content event associated with the first content item and a conversion event associated with the first entity;
• receiving a first request for content associated with a third client device;
• responsive to receiving the first request for content, selecting, based upon the first attribution data structure comprising the first attribution score determined based upon the first duration of time between the first content event and the first conversion event, the first content item from a first plurality of content items for presentation via the third client device;
• and
• transmitting the first content item to the third client device.

A non-transitory machine readable medium having stored thereon processor-executable instructions that when executed cause performance of operations, the operations comprising:

• detecting a first content event, associated with a first content item, performed by a first client device, wherein the first content item is associated with a first entity;
• detecting a first conversion event, performed by the first client device, associated with the first entity;
• determining, based upon the first content event and the first conversion event, a first duration of time between the first content event and the first conversion event;
• determining, based upon the first duration of time, a first attribution score associated with the first content event;
• storing a first plurality of attribution scores, comprising the first attribution score, in a first attribution data structure associated with the first content item, wherein an attribution score of the first plurality of attribution scores is associated with a content event associated with the first content item and a conversion event associated with the first entity;
• receiving a first request for content associated with a second client device;
• responsive to receiving the first request for content, selecting, based upon the first attribution data structure comprising the first attribution score determined based upon the first duration of time between the first content event and the first conversion event, the first content item from a first plurality of content items for presentation via the second client device;
• and
• transmitting the first content item to the second client device.
