How to install Simple Agent on Google Tag Manager

You will paste a single <script> tag in your Google Tag Manager site's Tags → New → Custom HTML → All Pages. No plugin, no app installation. Google Tag Manager official docs on custom code →

  1. 1

    Confirm the GTM container is installed

    If GTM is not already on the site, install the container first: the script block as high as possible in <head>, and the noscript block immediately after the opening <body> tag.

  2. 2

    Create a new tag

    Open tagmanager.google.com, select the correct container, go to Tags, and click New.

  3. 3

    Choose Custom HTML

    Click Tag Configuration and select Custom HTML.

  4. 4

    Paste the widget snippet

    Paste the complete Simple Agent snippet in the Custom HTML editor: <script src="https://simple-agent.me/widget/loader.js" data-agent-token="YOUR_TOKEN_HERE" async ></script>

  5. 5

    Attach the All Pages trigger

    Click Triggering and choose All Pages so the chat appears site-wide. Use a narrower trigger only if you intentionally want selected pages.

  6. 6

    Preview, then publish

    Use Preview / Tag Assistant to confirm the tag fires and the widget appears. Then click Submit, name the version, and Publish.

  7. 7

    Validate as a visitor

    Open the public site in a private browser tab and confirm the widget appears outside GTM Preview mode.

Frequently asked questions

Can I install Simple Agent without touching site code?
Yes, if the GTM container is already installed. If the container is missing, you still need one site-code change to add GTM itself.
Why does it work in Preview but not for visitors?
Preview is not a public release. You must Submit and Publish the GTM workspace version.
Does this work on builders like Wix or Shopify?
Yes when their GTM integration or custom-code access is correctly configured. If the builder blocks GTM or Custom HTML, use the builder-specific Simple Agent guide instead.
