This guide outlines location-based targeting tactics such as geofencing, geoframing, and geolocation targeting, which enable advertisers to reach their target audience based on geographic location. Geofencing involves creating a virtual boundary around a specific area, allowing ads to be served to mobile device users within that area. Geoframing utilizes mobile service carrier and device ID data to create custom audience pools for retargeting users who have visited a specific location. Geolocation targeting allows advertisers to target users based on broader geographic criteria, including countries, cities, and postal codes. The document also discusses best practices for implementing these tactics, such as ensuring a sufficient number of targeted devices and setting appropriate cost-per-thousand impressions (CPM) rates. Additionally, it emphasizes the importance of combining these methods with other targeting strategies while maintaining an adequate frequency cap for ad impressions.
