The Impact Consortium is Impact’s own proprietary identity graph, used to power Impact’s expansive attribution capabilities.
Advertisers who onboard into the Impact Platform have the option to join into the Impact Consortium. If the advertiser passes in customer identity data (say, their email address when the user logs into the secure area of the advertiser’s site) into our Universal Tracking Tag, Impact captures a deterministic identifier that ties a specific user to a device. When the user logs in across multiple devices, and when the advertiser fires the UTT tag across those devices, then the Impact platform is able to tie the user and their multiple devices.
The Impact Consortium is fully compliant to privacy legislation such as GDPR.
