At an event everything happens fast. People walk by, talk, look for friends or the next attraction. Your brand has only a few seconds to catch their attention. Exactly the amount of time described in Mel Robbins’ 5 second rule but here it is not about your action, it is about your audience’s reaction.
Whether someone notices your brand, stops to read your message or comes closer is decided in a split second. If you do not communicate why you are worth their attention in that moment, the opportunity is gone. That is why every advertising message, no matter the format or medium, has to work instantly. Literally in five seconds.
