You need to create Custom Dimensions in Google Analytics to set up Dynamic Remarketing. When a user views a content that is tagged with a vertical attribute like product ID then this information is passed to Google Analytics as Custom Dimensions. Since Google Analytics is linked with your Google Ads account, the product ID information from Custom Dimensions will be passed to Google Ads and this data will be used to target users who viewed that product using Dynamic Remarketing. Therefore, Custom Dimensions are important to send data about the specific products viewed on your website to Google Ads for Dynamic Remarketing. You need to create a Custom Dimension for each vertical attribute.
