DataLayer and the data layer. When I first started with web analytics, I couldn’t figure out whether these were the same thing or different. Every source claimed something different, and I hadn't yet learned how to read Google's documentation :) In any case, I can divide my entire work with GTM into two large periods: BEFORE I understood what the data layer is, and AFTER. Although the data layer is not the simplest thing to grasp, in this article I’ll try to present the information as clearly as possible.
