If you're a marketer describing the criteria for store visits conversion tracking, what would you say?

The correct answer is that store visits conversion tracking requires sufficient data to accurately report store visits and pass Google's privacy thresholds. This is because Google uses aggregated and anonymized data to estimate store visits, and a certain volume of data is needed to maintain user privacy and provide reliable reporting. Without sufficient data, the system cannot meet these thresholds. Store visits conversion tracking is not available in all countries/regions or for all business types; it's limited to specific regions and non-sensitive business categories. It also has implicit minimum impression and click requirements, as a certain level of ad interaction is necessary for Google to gather enough data to model store visits.
