Blue Bite executed an audience geofencing campaign across New York, Atlanta, and San Francisco to connect Mailchimp’s OOH presence with measurable website conversion activity. Bulletins, shelters, station dominations, and LINK screens were geofenced to capture audiences exposed to campaign-relevant OOH placements, with hyperlocal geofencing layered with an audience optimization stack to improve targeting precision. Mobile banner ads were then used to reinforce the OOH message and drive interested users to the Mailchimp website, where conversion activity was measured after ad engagement. Blue Bite also supported creative A/B testing to determine which messages generated stronger engagement and higher conversion volume. Reporting showed X,000 conversions across the three markets and demonstrated conversion lift from OOH exposure, giving Mailchimp, OMA, and PHD a clear view of how geofenced OOH amplification contributed to measurable website actions.
