There are four main types of buyer behavior:1. Engaged buyers are those who are actively searching for information about a product or service. They are typically more knowledgeable about what they want and are more likely to compare options before making a purchase.2. Passive buyers are those who are not actively searching for information. They may be influenced by advertising or word-of-mouth, but are not as likely to compare options or do extensive research before making a purchase.3. Impulse buyers are those who make a purchase on a whim, without much thought or planning. They are often influenced by emotion or a good deal, and may not consider all of the potential consequences of their purchase.4. Rational buyers are those who carefully consider all of their options before making a purchase. They weigh the pros and cons of each option and make a decision based on what is best for them, not just what is cheapest or most popular.
