Catherine received a significant amount of traffic to her online pet shop after launching her display campaign. Unfortunately, many visitors to her online shop didn't make a purchase. When creating a new display campaign, which marketing objective should Catherine choose in order to re-engage these visitors?

Catherine should choose "Drive action" as her marketing objective. This objective is specifically designed for remarketing efforts, aiming to re-engage users who have previously interacted with her website but haven't completed a desired action, such as a purchase. By targeting these visitors with relevant ads, Catherine can encourage them to return and finalize their purchase. "Increase leads" is incorrect because Catherine already has traffic; her goal is conversion, not lead generation. "Build awareness" is for introducing a brand to new audiences, which isn't her current need as visitors are already aware of her shop. "Influence consideration" aims to encourage users to explore products or services further, but Catherine's visitors have already done this; they just need a final push to purchase.
