If you're using Shopify, you’ll need to install the Signals code directly in your theme so it loads on every page of your store.
Where to add the code
In Shopify, go to Online Store → Themes
Click the ⋯ (three dots) next to your active theme and select Edit code
Open the file
Layout/theme.liquidPaste the Signals code immediately before the closing

⚠️ Important:
Do not place the code inside a {%raw%}{% section %}{%endraw%} block or in template partials. It must be added to theme.liquid so it loads on every page of your store.

The code must be installed directly in the theme as described above.
How to confirm the installation

Open your storefront in a browser
Right-click anywhere on the page and select View Page Source
Search for:
