The Impact of iOS 14 on Digital Advertising

The iOS 14 update from Apple has had a significant impact on the landscape of digital advertising, particularly on platforms like Facebook. This update introduced a new feature known as App Tracking Transparency (ATT), which requires apps to explicitly ask users for permission to track their activities across other apps and websites. This tracking is done via a mobile identifier called the Identifier for Advertisers (IDFA), which is crucial for advertisers to know whether someone bought an item or downloaded an app after they saw an ad that promoted it. As more people opted out of sharing those identifiers, increasingly bigger gaps were created in data for marketers.

The immediate impact of this change was a disruption in the way advertisers measure and plan their campaigns. The ability to track user behavior and attribute sales to specific ads became significantly more challenging, leading to a shift in the way advertisers perceive digital advertising. It's important to note that the effectiveness of advertising hasn't disappeared; it's just become more difficult to measure how effective those ads are1. This has led to a shift in the advertising industry, with marketers moving away from platforms like Apple and Facebook, which were heavily reliant on user tracking, and diversifying their ad spend across other platforms.

Companies have had to adjust and find new ways to navigate this new landscape. Some have turned to alternative methods of attribution, such as looking at overall consumer trends or leveraging third-party platforms to create a more comprehensive view of customer journeys1. Others have focused on diversifying their media spend and exploring new channels for advertising. This has also led to a broader shift in the way success is measured in advertising, with a greater emphasis on metrics like brand lift and brand awareness, rather than just conversions.

In conclusion, while the iOS 14 update has certainly posed challenges for digital advertisers, it has also opened up opportunities for innovation and forced the industry to reconsider its approach to advertising. As more data privacy measures are expected in the future, it will be interesting to see how the industry continues to adapt and evolve.
