Victor Antonio explains that there are three distinct types of buyers a salesperson will encounter, and each requires a different sales approach. The first type is the unaware customer, who needs to be made aware of a problem they are experiencing. The second type is aware but apathetic, necessitating a shift in the sales conversation to emphasize pain points and urgency to make them care about the issue. Finally, the third type of buyer is aware and cares but is scared of the risk involved, so the salesperson's job is to mitigate anxiety and increase certainty to facilitate the purchase.
