SKAdNetwork Adoption and Usage Rates (2024)

SKAdNetwork, a shortened version of StoreKit Ad Network, was launched by Apple in 2018 and marketed as a privacy-centric interface, which provides advertisers data on the aggregate level protecting individual user identity.

It took Apple a few years and a bit of strong-arming to make SKAdNetwork (SKAN for short) into the most used ad interface on iOS. In 2022, Apple banned IDFA tags, which led to Alphabet, Meta, Snap and other ad networks losing billions in value.

Unlike other ad frameworks, Apple only provides attribution data at the aggregate level and does not provide this in real-time. Instead, ad networks receive batches of postbacks – data on user behaviour – which can be sent up to a month after the initial click.

This delay is also marketed as a way for Apple to maintain the privacy of its users, while providing advertisers with meaningful data on ad impressions and clicks.

SKAN has become the lead attribution provider on iOS, with over 35 percent of all attribution going through this service. Apple Search Ads, which have similar privacy measures baked into them, are responsible for an additional 20 percent of attribution.

We have collected data and statistics on SKAN. Read on below to find out more.
