A Tag Management System (TMS) is a tool that helps website owners manage and deploy various tracking codes, or "tags," without needing to modify the website's code directly. Tags are snippets of JavaScript or HTML that collect data for analytics, advertising, and other purposes. By using a TMS, businesses can streamline the process of adding, updating, or removing tags, making it easier to track user behavior and optimize marketing efforts. With a TMS, users can organize tags in a centralized interface, allowing for quicker updates and better collaboration among teams. Popular TMS options include Google Tag Manager and Adobe Experience Platform Launch. These systems enhance website performance and ensure that data collection is accurate and efficient.
