Installing via Google Tag Manager
Add the Activly script to your site using Google Tag Manager — no code or developer access required.
Why use Google Tag Manager
If your site already uses Google Tag Manager, adding Activly takes about two minutes and requires no changes to your site's code. GTM acts as a container for third-party scripts, so once it is installed on your site, you can add Activly — and update it later — without involving a developer or touching any theme files.
This method works for any website where GTM is already running, including WordPress, Webflow, Squarespace, Framer, custom HTML sites, and most website builders.
Steps
- Log in to Google Tag Manager and open your account.
- Select the container associated with the site where you want Activly to appear.
- In the left sidebar, click Tags, then click New.
- Click Tag Configuration and choose Custom HTML from the tag type list.
- In the HTML field, paste your Activly script tag. You can find it at app.activly.io → Settings → Install Script.
- Click Triggering, then Choose a trigger.
- Select All Pages — this ensures the Activly script loads on every page of your site.
- Give the tag a clear name, such as
Activly Script, and click Save. - Click Submit in the top right corner to publish your container with the new tag.
The tag will not fire on your live site until you submit and publish the container. This is a GTM requirement and applies to all tag changes, not just Activly.
Verify the installation
After publishing, visit your website in a browser. Then go to app.activly.io → Settings → Installation Status. The status indicator should turn green within a few minutes, confirming the script is detected on your site.
If you want to verify before publishing, use GTM's built-in Preview mode. Click Preview in GTM, visit your site, and check that the Activly tag fires on page load. Once confirmed, exit preview mode and submit the container.
Troubleshooting
Tag is not firing after publishing. Check that you clicked Submit and not just Save. Saved changes in GTM are drafts — they only go live when the container is submitted and published. In GTM, look at the Version History to confirm a new version was published after your change.
Installation Status still shows undetected after 10 minutes.
Confirm the GTM container itself is installed correctly on your site. Open your site in a browser, right-click, and view page source. Search for GTM- — if the GTM snippet is not present, the container is not running on your site and no tags inside it will fire.
Script loading on some pages but not others. Verify the trigger is set to All Pages, not a specific page URL or path rule.
