People perceive things best when they’re directly in front of them, but this isn’t always an option for pole signs advertising to passing drivers. Still, you’ll need to take great care in determining the angle of your sign. As the ISA says, “every adjustment up, down, or to the side, and every angle of rotation, affects the visibility of that sign,” so make sure you know what you’re doing! Even getting your pole sign angle wrong by a few degrees can cost you thousands of impressions every day.
