Erica wants to add dynamic remarketing to a Microsoft Audience Network campaign. Which steps must Erica take before implementing dynamic remarketing?

To implement dynamic remarketing on the Microsoft Audience Network, Erica needs to ensure several foundational elements are in place. First, she must implement a Universal Event Tracking (UET) tag on her website. This tag collects user behavior data, which is crucial for building remarketing audiences and personalizing ad content based on their interactions. Second, she needs to create a Microsoft Merchant Center Store. This store hosts her product catalog, which is essential for dynamic remarketing to display relevant products to users. Finally, she must upload her product catalog (either as an image or a data feed) to the Merchant Center Store. This catalog provides the product information and images that will be dynamically inserted into her remarketing ads. Creating a search advertising campaign is not a prerequisite for dynamic remarketing on the Audience Network, as these are distinct campaign types, although they can complement each other.
