More than 80 percent of social network users are accessing social media on a mobile device in 2016. This means most social media ads are being viewed on mobile devices as well. Your mobile ads should be specifically designed for the small screen, incorporating images that are easy to view on a pocket-sized device. You can also take advantage of “geofencing” to target mobile users when they are in a specific zip code, so they only see your ads when they are close enough to walk in your front door.
