Which of the following best describes a marketing strategy?

A marketing strategy is best described as a long-term plan to achieve marketing goals. This entails a comprehensive approach that outlines how a company intends to reach its target audience, differentiate itself from competitors, and achieve specific objectives over time.

A long-term marketing strategy typically includes elements such as market research, analysis of consumer behavior, identification of target segments, development of messaging, and choice of channels for reaching customers. This strategic foundation allows businesses to allocate resources effectively, maintain consistency in branding and communication, and adapt to market changes while keeping long-term goals in mind.

In contrast, the other options focus on narrower activities or objectives. Short-term promotional tactics do not encapsulate the broader vision and planning necessary for a successful marketing strategy. Also, a method for conducting market research is just one component of marketing strategy rather than the complete picture. Finally, while managing costs in product development can be a part of overall business strategy, it does not inherently relate to the marketing strategy aimed at engaging customers and driving sales. Hence, the description as a long-term plan to achieve marketing goals accurately captures the essence of what a marketing strategy entails.
