Google Tag Manager is a free Google tool that lets you manage marketing and web analytics tags without editing a website’s source code directly.
Google Tag Manager provides a central visual interface for managing tracking scripts, known as tags. You can add new tags, update existing ones or disable them without changing the website’s code. This saves development time and reduces the risk of errors.
Common use cases include:
- Integrating Google Analytics, Google Ads or other tracking tools
- Setting up events for clicks (Event tracking), scroll depth or form submissions
- Managing Conversion tracking and remarketing tags
Using triggers (rules that determine when a tag fires) and Variables (dynamic values such as URL parameters or click IDs), Google Tag Manager provides a flexible way to manage Web analytics and tracking with precision.
