Private Click Attribution
Apple's Private Click Attribution is designed to provide less accurate, incomplete and time-delayed data to marketers about the events associated with their advertising.[1]
Apple acknowledges that for "ad click attribution to happen, some bits of data about what happened across two websites need to be sent."[2]
Apple's proposed Private Click Attribution relies on marketers sending the value of their conversion data to the publisher. However, Apple proposes that the data sent be a range rather than a specific value, which thus impairs the accuracy of the attribution algorithm.
Impact
By removing accurate, complete and real-time feedback to marketers, their ability to adjust the pricing and budget associated with advertising will be impaired. As the value marketers receive from advertising declines, so to will publisher revenues.
