Apple has been busy adding privacy-related features in iOS14. In December, with iOS 14.3, Apple added “Privacy Nutrition Labels” to the app store, clearly summarizing the applications privacy practices, including what information is collected and how it is used. App Tracking Transparency will be required with iOS 14.5 later this spring. Developers must ask users to opt in to tracking for advertising and other purposes.
In this blog, we give you a perspective on how marketers should be thinking about these changes. To learn more, don't miss our webinar Find Your Way in the Cookieless World on Thursday, March 25th | 10am PT - 1pm EST - 5pm GMT.
Apple’s iOS 14 updates are great for users’ privacy and Facebook is rolling with Apple updates by introducing breaking changes that facilitate enhanced privacy options. Since many of our Marin Social customers have questions about the impact of the iOS 14 updates, we want to assure customers that Marin is well positioned for iOS 14 updates along with providing a recap on the impact of iOS 14, especially for Facebook users and advertisers.
In terms of impact on Facebook users, Facebook is introducing a screen to prompt iOS 14 users to opt in to Facebook ad tracking. The carrot is better ad personalization. If users opt out, limited information about conversions, generated by FB ads to that user, will be available to advertisers.
In terms of impact on Facebook advertisers, Ads Manager contains detailed, account specific, action items for advertisers ex. selecting only eight conversion events for optimization efforts across an account. However, after the iOS 14 updates go into effect, advertisers can expect five fundamental changes:
Facebook will have limited conversion tracking for iOS 14 users that opt out. And many will opt out.
- Facebook pixel Cookie Window is limited to 7 days for clicks and same day for views; this may lower reported conversions. In terms of impact scope, a majority of Marin Social advertisers attribute Facebook conversions to clicks that occurred up to 28 days before the Sale/Form Fill. As such, we expect a majority of Facebook advertisers to be impacted by this change and we recommend proactively updating Attribution Settings.
- Advertisers with multiple domains can no longer attribute conversions from paid traffic across multiple domains. Customers that drive paid traffic to Domain A and convert the same visitors on Domain B will be directly impacted by Apple’s Private Click Measurement (PCM).
Audiences based on website interactions and mobile app engagements will decrease in Size and Reach.
- App advertisers will no longer be able to use ‘app connections targeting’ e.g. they cannot target people that are connected to App fans/followers.
- Facebook Audiences for retargeting (WCA and MACA) will contract in size due to iOS users opting out when the Facebook prompt is shown. Ideal audience size for retargeting and lookalike audience creation is 10,000 people; smaller audiences may yield relatively lower performance.
Publisher reported conversions should not be expected to reconcile with internal systems.
While both Google and Facebook are preparing for a cookie-less future, neither publisher has announced plans for cross-channel ad tracking.
- each Publisher only includes their view through conversions, but not the others
- Google includes ‘Modeled’ conversions and Facebook may include estimated metrics for iOS 14 ad campaigns at the ad and ad set level.
- Each Publisher has different attribution windows for paid clicks.
Advertisers will need to upgrade their tracking.
Facebook is offering a robust server-to-server solution to provide advertisers with more transaction (not user) level details. Cross-Channel advertisers should plan on deploying Search and Social publishers’ enhanced ad tracking solutions alongside a third party’s server-to-server solution like Marin Tracker. This way, advertisers can analyze paid channels performance under the publishers lens and via conversion metrics that are click based, de-duplicated, and measured under the same attribution window.
Facebook Ads will no longer offer demographic breakdowns for conversion events.
Facebook Advertisers should plan on running A/B tests to determine if there's a statistically significant difference in performance between demographic segments.
