Copley Advertising uses mobile geofencing to help clients reach their demographic in a set location. We tag all the IDs in the target location and then place ads in mobile apps. Once the user clicks on the ad we place their ID in a retargeting folder. Later on in the campaign, we will run a separate retargeting program. The click rate for a retargeting program is about 2x a regular program. We can drill down and place ads in Smartphones that are owned by users in the demographic you are trying to reach. Copley optimizes in real time and delivers granular reporting. Please go to copleyadvertising.com or email info@copleyadvertising.com. Thanks.
