1. A method comprising logging, based on cookie information, interactions associated with a content provider, wherein the interactions represent interactions of users with content presented by the content provider; logging a plurality of conversion events associated with products or services that are represented in the presentations of content; evaluating, by one or more processors, logged conversion and interaction data including: for each given conversion event in the plurality of logged conversion events: identifying one or more interactions that are linked to the given conversion event; determining, based on a comparison of a first timestamp for each identified interaction and a second timestamp of the conversion event, a time window before the given conversion event that is associated with each identified interaction; and for each identified interaction, incrementing an interaction count associated with the time window associated with the interaction; and determining one or more suggested time windows for the content provider for linking interactions and conversion events based on the interaction counts for each time window, wherein a suggested time window represents an amount of time before a conversion in which interactions are appropriately linked to the conversion; determining that a given suggested time window of the one or more time windows exceeds an average cookie age of cookies from which the cookie information was received; reducing the given suggested time window based on the determination that the given suggested time window exceeds the average cookie age; providing, through a user interface presented to the content provider, a presentation of the given suggested time window and others of the suggested one or more time windows; receiving, through the user interface, an acceptance of a suggested time window to be used; and using the accepted time window to determine attribution credit to be applied to specific interactions that are correlated to specific conversion events.
