A metric recommended for measuring loyalty goals is:

The correct answer is Repeat purchases, as this metric directly reflects customer loyalty by indicating how often customers return to buy from a brand after their initial purchase. Measuring repeat purchases allows businesses to assess the effectiveness of their loyalty strategies and understand customer retention rates. A high frequency of repeat purchases suggests that customers are satisfied with their experiences and are inclined to continue choosing the brand over competitors. In contrast, metrics like video completions or add-to-cart actions are more indicative of engagement or interest, rather than the deeper relationship that loyalty entails.
