Product line expansions refer to the strategy of adding new items to an existing range of products offered by a company. This can involve introducing new flavors, sizes, or variations of a product to meet diverse customer preferences and increase market share. For example, a beverage company might expand its product line by adding sugar-free or organic options. Such expansions can help businesses attract new customers and retain existing ones by providing more choices. However, they also require careful market research and planning to ensure that the new products align with the brand's identity and meet consumer demand effectively.
