What is SKAdNetwork & AdAttributionKit?

Also known as: SKAN, SKAdNetwork, AdAttributionKit

Quick definition

SKAdNetwork (SKAN), now extended by AdAttributionKit, is Apple's privacy-preserving attribution framework that reports app installs and coarse post-install conversion values to ad networks without revealing user-level identifiers, using delayed and anonymised postbacks.

Key points

Postbacks
SKAN 4 sends up to three postbacks over different windows with fine or coarse conversion values depending on crowd anonymity tiers.
Conversion values
Advertisers encode revenue or events into limited values; MMPs help design and decode these schemas.
Timer delays
Postbacks are randomly delayed, so campaign optimisation works on lagged, aggregated data.

Benefits

  • Works without ATT consent
  • Gives a privacy-safe baseline signal on iOS

Trade-offs

  • Limited granularity and delayed data
  • Small campaigns hit anonymity thresholds and lose detail

FAQ

Does SKAdNetwork replace an MMP?

No. SKAN supplies raw postbacks; MMPs collect, validate and model them alongside other sources to make them usable.
