What is the 3 3 3 rule in marketing?
The 3-3-3 rule is a content structuring heuristic: 3 seconds to catch attention, 30 seconds to hold it, 3 minutes to convert. It maps loosely to how modern platforms punish weak hooks (3s bail rate on video), reward mid-video retention, and reserve deeper information for viewers who signaled interest. Not a hard rule — a well-crafted 15-second video can convert; the point is that structure matters more than length.
