16. The memory device of claim 11, further configured to generate, from one of the plurality of servers, a sponsored content group comprising a sponsored content item for transmittal to the user device based on the sponsored content campaign, wherein the sponsored content event data is based on the sponsored content item.
17. The memory device of claim 16, further configured to track the sponsored content event data by de-duplicating sponsored content event data that corresponds to a single sponsored content event, wherein a duplicate sponsored content event data is not transmitted to the database.
18. The memory device of claim 17, further configured to de-duplicate the sponsored content event data based on at least one of a comparison between sponsored content event data and a comparison between sponsored content event data and an associated sponsored content item.
19. The memory device of claim 16, further configured to determine if the estimation of sponsored content event data received at the database from another server of the plurality of servers was accurate and in response to determining the estimate was inaccurate and the termination criterion were not met or exceeded, reopening the sponsored content campaign.
