However, this ability will now be limited: according to their official announcement, the change in the conversion window from 28 days on Facebook to 7 is due to the fact that “upcoming digital privacy initiatives affecting multiple browsers will limit companies’ ability to measure people’s interactions across domains and devices. Among those limitations is the ability for companies to attribute conversion events to an ad over longer attribution periods.”
And its open war with Apple plays a very important role in this .
«In early 2021, Apple will begin displaying its privacy notice, in compliance with its AppTrackingTransparency (ATT) framework. When Apple implements this notice and displays it on Facebook and Instagram, iran business email database data sharing limitations may impact app advertisers and those who optimize, target, and report on website events. We have developed upcoming updates to our attribution settings to counter the effects of Apple’s policy requirements.
“In January, we’ll be replacing the account-based attribution window with a new ad set attribution setting, which you can access during your campaign creation process in Optimization & delivery . Attribution settings are a time-limited window that ensures the conversions we measure are the same ones used to inform campaign optimization and provide more clarity when analyzing ad performance. We’ll be adding a corresponding Attribution Settings column to the reporting table so advertisers can see under which settings their ad results are reported.”
