Full disclosure - this is an assignment for a Print Advertising class I took at Bellevue College as a part of the Graphic Design Certificate Program. Our task was to take the print advertisements we did for Hershey's Dark Chocolate and turn them into digital banner ads. My opinion on the design of digital ads is the less text the better. Your illustration and a short headline should hook the viewer into clicking on the ad and being re-directed to your link. I felt like the Sin Better tagline plus the vice illustration was enough to get the click.
