Identity

LiveRamp RampID — Definition & Explanation

A deterministic identity solution that creates people-based identifiers from publisher first-party data (primarily email addresses). RampID has broad DSP integration and enables cross-device targeting without third-party cookies.

How LiveRamp RampID Works

Publishers pass hashed email addresses to LiveRamp, which translates them into RampIDs — pseudonymous identifiers shared with the advertising ecosystem. Buyers match RampIDs to their CRM data for precise targeting.

Why LiveRamp RampID Matters for Publishers

Publishers with RampID-enabled authenticated inventory command 50-150% CPM premiums over anonymous traffic. Building a first-party data strategy for RampID activation is one of the highest-ROI investments a publisher can make.
