Crowd Anonymity Tiers | Definition
At WWDC 2022, Apple announced updates to the fourth generation (v4.0) of its SKAdNetwork. With SKAdNetwork 4.0, Apple has defined three tiers of “crowd anonymity” based on attribution volume: low, medium, and high. With each tier, more granular data becomes available within the conversion postback. Note that Apple still does not provide precisely what the tier thresholds are — only that with more attributed volume, each tier is reached and more data is shared.
