Discuss how outside people or groups affect consumer buying decisions.

Outside people or groups, such as family and friends, can have a significant impact on consumer buying decisions. People may be more likely to purchase something that has been recommended by someone they trust because it demonstrates credibility and increases the likelihood of satisfaction with the product. Additionally, consumers are often influenced by the opinions of others when making buying decisions. For example, if a friend raves about a specific product or service, it may encourage others to try it out for themselves.

Marketing campaigns can also influence consumer buying decisions by providing information on products or services that is meant to convince potential customers to make purchases. This can include using celebrities in advertisements or launching promotional campaigns that make use of discounts or other incentives. Through these methods, advertisers aim to get people interested in their products and convince them to buy them. Lastly, reviews from other customers can play an important role in influencing decision-making since most people prefer to read what other users have experienced before committing their own money into a product or service.
