Store visits conversion tracking can be described in which way?

Store visits conversion tracking relies on aggregated and anonymized data to estimate foot traffic to physical locations. To ensure accuracy and protect user privacy, Google requires a sufficient volume of ad impressions and clicks before it can report store visit data. This threshold prevents the identification of individual users and ensures the data is statistically significant. Without enough data, the system cannot generate reliable estimates or meet Google's strict privacy standards. The other options are incorrect because store visits tracking does have minimum data requirements, is not universally available in all countries, and has restrictions on certain sensitive business types.
