# Install on Google Tag Manager

Add your snippet as a Custom HTML tag on all pages, and Tag Manager adds your agent's chat to every page.

## Put it on your site

1. **Copy your snippet** — In **Channels**, open **Chat widget**, press **Install** on your agent's row, then **Copy snippet**. **Where to paste** under it shows these steps when your site runs on Google Tag Manager. ![Where to paste on the Install tab, with Google Tag Manager chosen and its steps](https://hiy.ai/docs-shots/install/gtm.webp) *Channels › Chat widget › Install*

2. **Open your container** — At tagmanager.google.com, open the container your site loads.

3. **New tag, Custom HTML** — Open **Tags**, then **New**, then **Tag Configuration**, then **Custom HTML**.

4. **Paste, trigger All Pages** — Paste your snippet; under **Triggering** choose **All Pages**.

5. **Submit and publish** — Press **Submit**, then publish. Use **Preview** first to see it on your site.

**Good to know:**

- Tag Manager adds the snippet after the page loads, so **Check now** may say it isn't in the page's HTML; open the chat on your site once and it shows as Live.
- Use **Preview** in Tag Manager first to see it on your site.
- A Support Agent shows here when **Who can open it** is **Anyone on your sites**: Google Tag Manager can't run the code signed-in visitors need. [Open on your site](/docs/embed#open-on-your-site)
