Google Tag Manager
Google Tag Manager lets you deploy and manage marketing tags, analytics, and custom tracking scripts without modifying code.
What your site can do with Google Tag Manager
- Deploy arbitrary tracking scripts and marketing pixels centrally
- Configure trigger events for button clicks, form submissions, and scrolls
- Manage consent modes and cookie banners directly through GTM containers
Common use cases
| Example app | Example prompt | What happens |
|---|---|---|
| Centralized marketing tags | Use GTM to deploy Hotjar, LinkedIn Insight, and GA4 through one container. | All third-party scripts run via GTM container injection. |
| Custom click tracking | Trigger conversion events on specific button clicks configured in GTM. | Custom tags fire on interaction triggers without changing site code. |
Prerequisites
- A Google Tag Manager account and Web Container
- A Container ID starting with GTM- (e.g. GTM-XXXXXXX)
Set up Google Tag Manager
- In Google Tag Manager, open your Container.
- Copy the Container ID from the top header (starts with GTM-).
- In the Studio, open Connectors → Google Tag Manager, paste the Container ID, and republish.
Limitations
- Tags configured within GTM execute client-side and can be blocked by ad blockers.
- Incorrectly configured tags in GTM can impact site performance or page load speed.
