Marks and Spencer can improve its segmentation, targeting, and positioning (STP) approach by understanding the actual needs and requirements of its target market. This involves identifying what type of products customers prefer to purchase and segmenting them accordingly. Additionally, considering a range of factors that consumers consider when purchasing a product can support proper segmentation and attract customers. Further, behavior-based segmentation, targeting customers based on real benefits derived from purchasing products, and positioning products based on their attributes and differences from competitors can enhance the overall performance of the business. This approach is effective in attracting large numbers of customers, meeting stakeholder expectations, and being feasible for the company with proper marketing resources.
