Apple’s IOS Release WILL Effect Your Facebook Ads


You Must Taken Action Now To Prepare For Aggregate Event Measurement Tracking.

Apple has announced changes with iOS 14 that will affect how Facebook receives and processes conversion events from tools such as the Facebook pixel.
Apple will begin to require that all apps in the App Store show a discouraging prompt to users on iOS 14 devices, in accordance with their App Tracking Transparency framework.  Apple’s policy will prohibit certain data collection and sharing unless people opt in to tracking on iOS 14 devices via the prompt. As more people opt out of tracking on iOS 14 devices, ads personalisation and performance reporting will be limited for both app and web conversion events.


In order to reduce the disruption and impact of this change, Facebook will be changing how it receives and processed data from these users.

The new Aggregate Event Measurement tracking system allows you to continue running effective campaigns whilst maintaining your user privacy.

Preparation Is Key

You will need to make changes to your account, whether you run ads with an agency or on your own.

Stage 1:  You will need to verify your domain within your own Facebook Business Manager account. This is because all Pixel events, from the release of Apple’s IOS14.5 (which is expected towards the end of February 2021), are required to be updated to Facebook’s new ‘Aggregated Website Events’.

You must verify your website yourself.  This cannot be done by anyone else as your website should only be verified in your account.

Stage 2:  Once you have verifired your domain, you’ll then need to configure eight preferred web conversion events per domain in Events Manager. Aggregated Event Measurement limits domains to eight conversion events that can be used for campaign optimisation.  Facebook will initially configure the conversion events that they believe are the most relevant to your business based on your activity. All other events will be made inactive for campaign optimisation and reporting.
