Feature design. Use behavioral, contextual, and content interaction signals; avoid leaking sensitive attributes; enforce fairness and consent constraints.

Frequently asked questions

What is lookalike modeling?

Modeling. Train calibrated classifiers and embeddings to capture similarity; validate with uplift and holdouts, not just AUC; present ranges and confidence.

How are synthetic audiences created?

Synthetic cohorts. Generate representative profiles for planning and testing without exposing real identities; disclose limitations.

What is the purpose of activating synthetic audiences?

Activation. Export audiences to platforms with guardrails and frequency caps; monitor performance and fairness across segments.

How should governance be approached when using these technologies?

Governance. Monitor bias, document limitations, and align with privacy policies; maintain audit trails.
