In this video, you’ll learn how to create and use the DOM variable in Tag Manager to capture data directly from elements on a webpage. We’ll show how to configure it using an element’s ID, CSS selector, or XPath, and explain its two modes: extracting text or checking element presence. You’ll see how to identify elements in DevTools and test your setup in debug mode to confirm the variable works correctly. By the end, you’ll know how to use DOM variables to detect or extract on-page elements and improve the accuracy of your tracking and trigger logic.
