The Evolution of Context

No PII, no problem. Zefr’s technology enables independent contextual data, based on each brand’s suitability standards. The result is effective and transparent targeting, without being creepy.

Precision

Not every type of content is suitable for every brand. Zefr’s precise targeting technology enables brands to activate scaled contextual campaigns, based on their distinct suitability and risk tolerances. Ensuring each ad is aligned with the right content, every time.

Control

Pre-flight control with content-level transparency. Our Context DMP enables brands to manage and modify their suitability definitions based on content, rather than relying on legacy tools like keyword-blocking.

Effectiveness

Unlike static solutions, Zefr’s dynamic targeting drives more efficient workflows and more effective campaigns. Effective contextual data delivers brand suitability without compromising reach. Ensuring your campaign objectives are met. Always.
