A Data Layer is a JavaScript object that contains information about a website’s content and interactions. It acts as a bridge between the website’s front-end (the visual presentation of the website) and the back-end (the database and server that store and process data).
The Data Layer stores data such as user interactions, events, and content attributes in a structured format, making it easily accessible for tracking and analysis by analytics tools such as Google Analytics.
This layer allows for the collection of data from multiple sources and the creation of a consistent and centralized view of website data, making it easier to analyse and optimize user experiences.
