Tag management system (TMS) simplifies the deployment and management of tags. Tags are snippets of code or tracking pixels embedded in a website or app to collect data and facilitate third-party services. These tags are used for various purposes, including analytics, advertising, marketing, and personalization. TMS allows users to add, edit, and manage tags without directly altering the website's code, often through a user-friendly interface. This helps streamline the process, reduces the need for constant IT involvement, and improves website performance by loading tags asynchronously.
