Install SourceTag on Weebly

Add SourceTag’s tracking script to your Weebly site through the header code settings. No third-party apps required.

Step 1: Copy your script tag

In your SourceTag dashboard, go to your site’s detail page and copy the script tag. It looks like:

<script src="https://cdn.sourcetag.io/scripts/YOUR_SITE_ID/st.js" async></script>

Step 2: Add to Weebly

1. In the Weebly editor, go to Settings
2. Click the SEO tab
3. Paste the script tag into the Header Code field
4. Click Save

Step 3: Publish

Publish your Weebly site. The tracking script is now active on every page.

Step 4: Test

Visit your published site with UTM parameters:

https://yoursite.com/?utm_source=test&utm_medium=cpc&utm_campaign=weebly-test

Submit a form on your site and check wherever your form submissions are received. The submission should include hidden fields with attribution data.

Notes

• The script works with Weebly’s built-in form elements. Hidden fields are added automatically.
• If you’re using embedded third-party forms (Typeform, HubSpot, etc.), the script will detect those too via MutationObserver.
• Weebly is now part of Square. If you’re managing your site through Square Online, the setup steps may differ slightly — look for the custom code or script injection option in the site settings.
• Browser cookies are limited to 7 days on Weebly (no server-side cookie option available for Weebly sites currently).
