¿Cuál de las siguientes opciones describe la estrategia de un anunciante con un objetivo comercial de lealtad?

The correct answer is "Offering an incentive for customers to subscribe to a monthly product box." This option directly addresses customer loyalty by encouraging repeat purchases and long-term engagement through a subscription model. Loyalty strategies aim to retain existing customers and foster brand advocacy. "Showing a product to more potential customers through social media" is a brand awareness or consideration strategy, focused on reaching new audiences, not retaining existing ones. "Creating a new web banner to get more visits to your landing page" is a traffic generation or consideration strategy, designed to attract initial interest, not to build loyalty among existing customers.
