Instead of asking the agent to add each tracking script separately, you add GTM once and manage everything else from the GTM interface. Available on all plans ## Why use Google Tag Manager * **One setup, any tool.** Add GTM once and connect Google Analytics, Meta Pixel, LinkedIn Insight Tag, and more, all without touching your project again. * **Full control from the GTM dashboard.** Add, update, or remove tags anytime without having to prompt the agent each time. * **Understand exactly how visitors use your site.** Track clicks, form submissions, page views, and custom events with GTM triggers. * **Test before anything goes live.** GTM's preview mode lets you confirm tags are firing correctly before you publish. ## What you need Before you start, make sure you have: * A **Google Tag Manager account**. Create one for free at [tagmanager.google.com](https://tagmanager.google.com) * Your **GTM Container ID**. It looks like `GTM-XXXXXXX` and you'll find it at the top of your GTM workspace ## Add GTM to your project Open the chat in your Macaly project and ask the agent: ``` Add Google Tag Manager to my site. My container ID is GTM-XXXXXXX. ``` The agent adds the GTM script to your project in the right place, both the `` and `` portions, following Google's recommended setup. Replace `GTM-XXXXXXX` with your actual container ID from your GTM dashboard. ## Verify it's working After the agent adds GTM, you can confirm it's active: In your GTM dashboard, click **Preview**. Enter your Macaly project's URL. Google Tag Assistant opens in a new tab and connects to your site. You should see your container listed as **connected**. Browse your site and watch the Tag Assistant panel. Any tags you've configured in GTM should appear as **fired**. ## What to do next Once GTM is running, you manage everything from the GTM dashboard: | Task | Where to do it | | ----------------------- | ------------------------ | | Add Google Analytics | GTM dashboard → Tags | | Add Meta Pixel | GTM dashboard → Tags | | Track button clicks | GTM dashboard → Triggers | | Track form submissions | GTM dashboard → Triggers | | Add conversion tracking | GTM dashboard → Tags | **GTM vs adding scripts directly.** If you only need Google Analytics and nothing else, you can skip GTM and [add GA4 directly](/en/integrations/google-analytics). GTM is worth it when you plan to use multiple tracking tools or want to manage tags without returning to the chat. **Cookie consent.** GTM tags often set cookies that track visitor behavior. If your site has visitors from the EU, UK, or other regions with privacy laws, you are responsible for ensuring a cookie consent solution is in place before GTM tags fire. ## Good to know * GTM doesn't slow down your site when set up correctly. The agent follows Google's async loading recommendation * You can use GTM's **built-in variables** to track page paths, click URLs, form IDs, and more without any extra code * If you need the agent to fire a custom event (like a successful booking or purchase), just ask. The agent can push events to GTM's data layer
