ID5

ID5 is a universal identity platform designed for digital advertising that creates persistent user identifiers across different environments. It provides a privacy-compliant alternative to third-party cookies by maintaining consistent user recognition across websites and devices. The platform helps publishers and advertisers improve ad targeting, frequency capping, and attribution measurement. ID5 integrates with major advertising platforms and supply-side platforms (SSPs) to enable better programmatic advertising campaigns. It uses deterministic and probabilistic matching techniques to maintain user identity while respecting privacy regulations like GDPR and CCPA. The service helps increase ad revenue for publishers by improving match rates with demand-side platforms.
