Which apps the stores choose to spotlight, and what those picks have in common. Featured apps tend to share traits worth studying, recent quality updates, strong creative work, participation in seasonal events, and timing that matches what the store wants to promote that week. Tracking who gets featured in your category, and what they shipped just before it happened, is the closest you can get to understanding what the stores look for, and it gives you a concrete checklist to work toward before your next big release.
