No charge for using the platform. You get charged per 1000 impressions and the PPM is very affordable. I tried using it for a few tradeshow events. This works great if you are trying to get immediate foot traffic from a general target audience to a local event, retail store sale, doctor office promo, school enrollments, or church invitations. It's based on address and/or radius/coordinates, so location is key. You can also do a retargeting campaign for served impressions on both mobile and desktop. Static ads and video ads. My account rep was super helpful. Nice support team!
