As stated by Cialdini, highlighting similarities that a salesperson has with a customer increases likability and approval. Cialdini references the fact that infants tend to smile more when people match their facial expressions. Besides this,
psychological research has delved into why finding similarities with others boosts likability. When an individual realizes they have similarities with another individual, they feel that their own interests and attributes are validated. For instance, if a customer discovers that a salesperson has a similar passion for web design, the customer feels a boost of confidence that their passion is shared valued by others, making them feel good about themselves.
Finding similarities is an easy process during any kind of interaction, including sales. A game that I introduce during my
sales training practices with salespeople who find it difficult to connect to others outside of a business conversation is called "me too". The goal is to have a conversation with your counterparty that leads you to say "me too" as many times as possible. For instance, ask a prospect how they like to spend their vacation to get to activities which you also enjoy. The prospect likes sailing? "Me too!". The prospect enjoyed visiting London? "Me too!", etc… Be sure to be genuine and curious and the conversation will take you far enough to establish a bond.
This technique establishes similarity and builds rapport between a salesperson and the customer. Once a customer sees that the salesperson is more like themselves, they will subconsciously begin to like and trust the salesperson.
