Shared Audiences

Shared Audiences, based in Weston, Connecticut, operates a geofence event advertising platform aimed at B2B marketers, event sponsors, and exhibitors who want to reach attendees of trade shows, conferences, and expos. Rather than a general marketing agency, the company focuses specifically on location-based advertising tied to in-person events, working with clients globally to set up and strategize campaigns around specific venues. The core method is Geofence Event Targeting: a virtual boundary is drawn around an event venue using GPS, and when mobile devices enter that zone, digital ads are served in real time, with retargeting of that audience continuing for up to 30 days afterward. Campaigns can run as display, video, or connected TV ads, with over 30 display ad sizes supported and a maximum file size of 200 KB for accepted GIF, JPG, or PNG creative. The launch process involves drawing the geofence, entering event details, selecting ad formats, adding a landing page, and uploading creative assets, though ad design itself is the client's responsibility. Pricing is structured per event by ad type, with volume discounts for booking multiple events, and includes delivery, retargeting, and performance reporting. A 3% processing fee applies to credit card payments, and setup is described as achievable without technical assistance.
