什么是 95-5 法则？

The 95-5 rule, a key concept in marketing effectiveness, states that at any given time, 95% of potential buyers are not actively in the market for a specific product or service. This means only a small fraction (5%) are actively looking to purchase. Marketers must therefore focus on building long-term brand salience and mental availability with the 95% who are out of market, so that when they eventually enter the market, their brand is top-of-mind. The incorrect options suggest either a majority of buyers are in-market (which contradicts the rule) or misinterpret the rule's focus on buyer behavior.
