If you want to really know the key to marketing and driving up sales at the consumer level it’s knowing your customer. And the only way to truly understand your customer is to watch your customer’s behavior. That’s what Nielsen does. In fact they study the way people behave in grocery stores to determine how their body language relates to purchase decisions across 30 food categories. Once you know the triggers you can leverage their hot buttons and trigger a change in their behavior. In results announced August 15th, Nielsen cited four different “shopping modes:” auto-pilot, variety-seeking, buzz, and bargain hunting.
