For Dynamic Re marketing, what needs to be set up in Google Analytics to collect information from the data layer?

To collect information from the data layer for Dynamic Remarketing in Google Analytics, you need to set up a Data Layer variable in Google Tag Manager. This variable type specifically reads values pushed into the data layer (e.g., product IDs, page types), making them accessible for use in tags like Google Analytics. A Constant variable holds a fixed value, not dynamic data from the data layer. A Google Ads variable is used for Google Ads-specific configurations, not for extracting data layer values for Analytics. An Event variable is used to capture event names or parameters from an event, but a Data Layer variable is the direct method for accessing general data layer objects.
