Rapport is a process of recognizing and sharing values with others through communication. Building rapport allows for productive conversations by engaging attention and gaining trust, which helps attract customers and close sales. The key to building rapport is pacing, which is unconsciously matching and mirroring others' behaviors to develop shared values. Elements of pacing include matching posture, mannerisms, voice, and words used. Understanding primary communication styles like visual, auditory, and kinesthetic can help mirror others during communication.
