What is ATOM ?

ATOM (or Anonymous Targeting on Mobile) offers privacy-first targeting and monetization capabilities that puts user privacy at the forefront. Mobile app developers can monetise their unaddressable users without relying on persistent and diminishing iOS device identifiers, like IDFA.

ATOM is a small (1.5MB) library that is integrated with an ad SDK of the app. ATOM monitors app usage patterns anonymously and enriches the ad requests with relevant cohorts at a time. The enriched ad requests can be targeted by an advertiser seamlessly, when a specific campaign includes the selected cohorts.

Why ATOM ?

So how does ATOM help you, as a developer? ATOM enables marketers to continue reaching the right audiences without compromising on privacy. ATOM also helps publishers and developers like you, monetise effectively in a privacy-safe way.

  • Reclaim Pre-IDFA eCPMs on anonymized users. Monetization with ATOM delivers higher eCPMs, compared to no-IDFA traffic.
  • Enrich bid-level signals for brand targeting. Ensure that 100% of your inventory and your users are addressable by advertisers, even without IDFA.
  • Match anonymous users to relevant cohorts. Further, learn which cohorts and ads drive your users. ATOM currently supports 10+ standard cohorts that are constantly updated frequently.
  • Above all, monetise effectively in a privacy-safe way. ATOM complies with the Apple ATT guidelines and delivers fully anonymous user engagement, requiring no PII (or personally identifiable information).

ATOM Cohorts and Taxonony

By definition, a cohort is a group of people who have something in common. The ATOM SDK relies on the following anonymous signals to analyse and calculate on-device cohorts.

Device: Device OS, Manufacturer, Model, Timezone, Sensors.
App: Bundle ID / App ID, App starts, Session time, Dayparts.
Ad: Ad events, Clicks, Video started, Cohort affinity.

We offer 14 standard cohorts today.
