Explanation:

In marketing, brand loyalty describes a consumer's positive feelings towards a brand, and their dedication to purchasing the brand's products and/or services repeatedly, regardless of deficiencies, a competitor's actions, or changes in the environment. It can also be demonstrated with other behaviors such as positive word-of-mouth advocacy. 

Corporate brand loyalty is where an individual buys products from the same manufacturer repeatedly and without wavering, rather than from other suppliers. Loyalty implies dedication and should not be confused with habit with its less-than-emotional engagement and commitment. Businesses whose financial and ethical values (for example, ESG responsibilities) rest in large part on their brand loyalty are said[by whom to use the loyalty business model.
