Online Store → Preferences holds the store-wide settings for your site: the home page title and meta description, a social sharing image, Password protection (useful before launch), the cookie banner and your Google Analytics 4, Google Tag Manager and Meta pixel IDs.

Custom HTML tags in Tag Manager. Your store only runs scripts it trusts, to keep shoppers safe. Tags that load a script file work as they are. A Custom HTML tag with code written inside it needs one extra step in Tag Manager, once:

1. In Tag Manager, open Variables → New and choose DOM Element.
2. Set Selection Method to CSS Selector, Element Selector to script[nonce] and Attribute Name to nonce. Name the variable nonce and save.
3. In each Custom HTML tag, change <script> to <script nonce="{{nonce}}">, then publish your container.
