I ran some numbers, since there's been a bunch of talk about students not getting any digial ads served to them about football games. Using a 15 mile radius around zip 70504, the total market size to those who id as students is about 16,000. You could serve up 160,000 gross impressions (each student 10x) via phone, laptop, or social media for $1600. 6 home games, $9600 total investment.
So, lets say 2000 students show up each game, half bring a friend with a ticket..what are those $10? And everyone averages $15 in concessions. Over 6 home games, ROI is $270,000 Gross...wouldn't know the net, net...but you see how this works...
