What is the technical term for “an allowable period between the moment someone viewed or clicked on your ad and the moment they took action, in which an advertiser believes there was a causal relationship”?

The attribution window is the technical term for the time frame during which a conversion is credited to an ad interaction—either a view or a click. It defines the period in which an advertiser considers a conversion to be causally related to the ad. For example, if someone clicks an ad and makes a purchase within a 7-day attribution window, that conversion is attributed to the ad. This window helps advertisers measure campaign effectiveness while accounting for the natural delay between ad exposure and user action.
