Your body language would be the most important to create an impressive first impression on your potential client. Body language is the non-verbal communication that includes your posture, gestures, facial expressions, eye contact, and physical distance. Body language can convey your confidence, enthusiasm, professionalism, and trustworthiness. According to research, body language accounts for 55% of the impact of a first impression, while tone of voice accounts for 38% and words account for only 7%. The other statements are less important than body language. Volume of your voice is part of your tone of voice, which can affect how your words are perceived by your potential client. However, volume alone is not enough to create an impressive first impression; you also need to consider your pitch, pace, and intonation. Your words are what you say to your potential client, which can include your introduction, your value proposition, and your questions. Your words are important to convey your message and establish rapport with your potential client. However, your words have less impact than your body language and tone of voice on your first impression. Tone of your voice is how you say your words, which can include your volume, pitch, pace, and intonation. Your tone of voice can influence how your potential client feels about you and your message. However, your tone of voice has less impact than your body language on your first impression. References: Unit 10: Sales Process, [The Importance Of Body Language In First Impressions]
