SolarEngine adopts the following attribution methods:

Method	Description	Accuracy
Deterministic Attribution	Device matching	YES
Probabilistic Attribution	IP address & user agent matching	NO

In SolarEngine, click-through attribution takes precedence over view-through attribution. For example, if a user:

Clicks an ad on July 1
Views an ad on July 2
Installs the app on July 3

Then, even though the latest ad interaction falls on July 2, the credit goes to the ad click on July 1.

Deterministic Attribution

Deterministic attribution is achieved by matching the device ID sent by the ad network and the device ID reported by the SolarEngine SDK during app activation.

Here are the IDs available for device matching:

iOS devices: IDFA, IDFV
Google Play supported Android devices: GAID, OAID, Android ID, IMEI, MAC address
Google Play not supported Android devices: OAID, Android ID, IMEI, MAC address

Device IDs can be encrypted through SHA1 or MD5 in tracking links.

Probabilistic Attribution

Probabilistic attribution is an alternative solution when deterministic data, like tracking codes or ad identifiers, are insufficient or unavailable. Given the higher accuracy and reliability of deterministic attribution, it takes precedence over probabilistic attribution. In other words, within the attribution window, if conditions allow, we will use deterministic attribution first.

If you need to enable probabilistic attribution, please report device parameters such as IP and user agent (UA).
