Here is a mockup of a Twitter ad we released to engage students in Study Abroad at Western Kentucky University. We have a picture of a student in a study abroad country, waving their red towel. We have a phrase at the top to interest those who see the picture, and have a link underneath the picture for people to see the list of study abroad programs WKU offers.
These were the categories we chose to target based on the demographics of people on Twitter.
These were a few more targets we listed to place our ad in the right news feeds.
