Luan quiere alcanzar a compradores que han mostrado interés en sus productos o productos similares en Amazon.com. ¿Qué tipo de señales debería usar?

In-store interactions" (Interacciones en tiendas) is the correct answer because it directly refers to signals gathered from shoppers' activities on Amazon.com, such as product views, searches, and purchases. These signals are ideal for reaching buyers who have shown interest in specific products or similar items on the platform. "Media interactions" (Interacciones con medios) refers to engagement with ads or content outside of direct product browsing, which is less precise for identifying specific product interest. "Campaign remarketing" (Remarketing de campaña) is a strategy that uses these signals, but it's not the type of signal itself.
