What targeting method involves geographic targeting based on GPS data?

Geo-fencing is a targeting method that utilizes geographic boundaries to deliver advertisements to users based on their real-time physical location, determined through GPS data. This approach allows advertisers to create virtual perimeters around a specific geographical area and target users who enter these areas, providing a powerful way to reach consumers at the right place and time.

For instance, a retailer could use geo-fencing to send promotional messages to customers who enter a predefined radius of their store, enhancing the relevance of the messaging based on the user's proximity to the business. This method is especially effective for driving foot traffic and boosting local engagement.

In contrast, other targeting methods do not focus primarily on geographic location through GPS. Date/Time - Daypart Targeting is centered around timing to deliver ads, while Cross Device Targeting connects users across various devices. Keyword Targeting involves serving ads based on specific keywords searched by users, which is independent of their geographic location. Thus, geo-fencing stands out as the method specifically designed for targeting users based on their GPS-derived geographic data.
