Alan has introduced a new line of scooters on his website and is using a Google Display Ad campaign to promote them. He selects “Build awareness” as the marketing objective for his campaign. Why would Alan choose “Build awareness” as his marketing objective?

Alan would choose "Build awareness" as his marketing objective because this objective is designed to introduce a new product or brand to a wide audience. For a new line of scooters, reaching a broad audience is crucial for initial visibility and recognition. The other options are incorrect because they align with different marketing objectives: "To reengage users who previously showed interest in his scooters" describes remarketing, which falls under objectives like "Drive sales" or "Generate leads." "To dynamically generate ads, based on an audience's interest in scooters" refers to dynamic creative or dynamic remarketing, also typically used for driving sales or leads. "To engage with audiences who previously bought his scooters" is a customer retention strategy, often part of "Drive sales" or "Build loyalty" objectives.
