A data layer is a JavaScript object used in tracking and analytics. It allows structured data to be passed to tools like Google Tag Manager.
Understanding Data Layer in SEO
A data layer is an organized set of information embedded on your website that communicates with analytics tools and tag managers. It provides detailed insights about users, page content, and interactions, enabling precise measurement of SEO performance. For example, it can track clicks on links, form submissions, or product views without interfering with site speed. By having a properly implemented data layer, SEO professionals gain reliable data to make informed decisions, improve user experience, and optimize content strategies.
