Deterministic matching uses confirmed, verified data points to identify visitors—like matching an exact email address or phone number to a person. It's accurate and reliable.

Probabilistic matching uses algorithms to guess who a visitor is based on patterns—like estimating that a visitor from a specific company with certain behavior is likely a certain person. It can be wrong.

SITE ID uses deterministic matching, which means higher accuracy, more reliable data, and no guessing. Probabilistic systems may be cheaper, but they degrade over time and can lead to costly mistakes.
