A shopping mall plans to send targeted offers to customers connected to their WiFi network. Which type of data about the customer will be most valuable to send these offers?

Geolocation is the most valuable data for sending targeted offers to customers connected to a shopping mall's WiFi network. This information allows the mall to understand the specific location of customers within the premises. By leveraging geolocation data, the mall can deliver personalized offers based on where customers are situated, such as near specific stores or product displays. This real-time insight enhances the relevance of the offers, increasing the likelihood of customer engagement and conversion.

While time of day could provide some context about shopping habits, it does not offer the precise location needed to target specific areas within the mall. Weather data may influence shopping behavior but is less directly actionable in terms of geolocation-based targeting within a retail environment. Therefore, geolocation stands out as the critical data point for effective targeted marketing in this scenario.
