To set up Dynamic Re marketing, what must first be created in Google Analytics?

To set up Dynamic Remarketing, you must first create custom dimensions in Google Analytics. These custom dimensions capture specific attributes of your products or services, such as product ID, industry, or value, which are then used to personalize remarketing ads. Without these custom dimensions, Google Ads cannot effectively segment your audience based on their interactions with specific product details on your site. Custom segments are used for analysis within Analytics, custom metrics track specific numerical values, and custom reports organize data, but none of these directly enable the product-level data collection required for Dynamic Remarketing.
