We have collectively lost access to around 70% of Identifier for Advertisers (IDFAs) as research shows only about 30% of users give permission to be tracked when shown Apple’s App Tracking Transparency (ATT) prompt to opt-in to app tracking. For a user who does not share permission to be tracked, the IDFA returns a null value to the app, ad network and measurement partner. This has upended how the digital advertising ecosystem collects and processes device IDs. Jayakrishnan Chandrasekaran from InMobi discusses here what can be done to offset this.
