Undifferentiated marketing, also known as mass marketing, is a marketing strategy in which a company targets the entire market with a single product or service, without any specific segmentation or targeting. This approach assumes that all consumers have similar needs and preferences, and therefore, the same marketing mix can be used to reach and persuade them. Undifferentiated marketing is often used for products or services that have universal appeal and do not require customization for different segments. However, it can be a risky strategy as it may not effectively reach all consumers and can lead to a lack of differentiation from competitors.
