Event | Sports | Trade Show | Concert | Marketing & Advertising How Event Targeting Works A virtual geo-fence is traced around an event location where the advertiser wants to build an audience based on their visit to that particular location during a set, scheduled timeframe. When the customer enters the geo-fenced location during the set timeframe, they will then become a part of an audience that can later be targeted following the event. As the user visits various apps downloaded on their phone or browses the internet on the mobile browsers, they begin to see ads from said advertiser. User can see those Ads for 1 day and up to 30 days after he/she has entered the geo-fence. We can target people on mobile devices, tablets, and desktops when they’re on wifi networks or through GPS.
