Surprise your advertisers with the unexpected before it becomes the expected.
Let us explain.
Right now, advertisers may not know that they can have control of their screen campaigns at their fingertips. They may not know that they can upload full-size creatives, post ads with just a photo and caption, control ad frequency, schedule creatives, and view real-time proof of playing reporting. BUT, they will soon.
Surprise them with these features while it's unexpected. Don't wait until it's the expectation that you aren't meeting.
