What type of knowledge is least relevant for consumers to learn from marketers?

Consumers generally benefit from understanding how to effectively use a product, the improvements or enhancements made to a service over time, and insights from other consumers through product reviews. Each of these areas not only assists in the decision-making process but also enhances the overall consumer experience and satisfaction with the product or service.

In contrast, company knowledge about product background is typically less relevant for consumers. While it may provide context or history about a product, it does not directly contribute to a consumer's immediate need for understanding how to use the product, the ongoing value they can expect from it, or real-world experiences shared by other users. Therefore, while some consumers may find interest in the background of a product, it does not have the same direct impact on their purchasing decisions or product satisfaction compared to the other types of knowledge presented.
