A marketing strategy with the goal of keeping individual customers over time by offering them products that exactly meet their requirements is marketing.

The marketing strategy you are referring to is known as "relationship marketing."

Explanation

1. Definition: Relationship marketing focuses on building long-term relationships with customers, rather than merely acquiring new customers. This approach emphasizes customer retention and long-term engagement.

2. Goals: The primary goal of relationship marketing is to meet the specific needs of individual customers, ensuring their satisfaction and loyalty over time. This is often achieved by personalizing product offerings based on the customer’s preferences and behaviors.

3. Implementation: Businesses implementing relationship marketing may use various tools and strategies, such as customer feedback systems, loyalty programs, and personalized communication via email or social media.

4. Benefits: A strong relationship marketing strategy can lead to increased customer loyalty, higher customer lifetime value, and reduced marketing costs since retaining existing customers typically costs less than acquiring new ones.

In summary, relationship marketing is about enhancing the customer experience by providing tailored products and services that meet their unique needs, ultimately resulting in long-lasting customer connections.
