Ghost
Ghost has a built-in code injection box that adds scripts to every page on your site.
Open Settings
In your Ghost Admin (usually https://example.com/ghost), click Settings in the left sidebar.
Go to Code injection
Click Code injection.
Paste the snippet
In the Site Header box, paste the snippet:
<script defer src="https://api.snowanalytics.app/sa.js" data-site="YOUR_SITE_ID"></script>Save
Click Save. Ghost injects the snippet into the <head> of every page.
Verify
Visit your site in a browser, then check the Live view in the Snow dashboard. See Troubleshooting if nothing appears.
