投放展示广告系列之后，小琳的在线宠物店吸引到了可观的流量。遗憾的是，很多访问者浏览了她的网店后没有购买任何东西。 为了再次与这些访问者互动，小琳制作新的展示广告系列时应当选择哪个营销目标？

The correct marketing objective is "Attract action" (吸引用户采取行动) because the goal is to re-engage visitors who previously browsed but didn't purchase. This objective focuses on driving conversions, such as completing a purchase, which aligns with remarketing efforts. "Influence consideration" (影响考虑度) is for users who are still researching, not those who have already shown interest. "Increase leads" (增加潜在客户数量) is for gathering contact information, which isn't the primary goal here. "Build awareness" (培养认知度) is for introducing a brand to new audiences, not for re-engaging existing ones.
