BigCommerce

Add the tag to every page of a BigCommerce store, with Script Manager.

In your control panel, go to Storefront, then Script Manager, and choose Create a Script. Give it a name, set its location to Head and its pages to All pages, choose Script as its type, paste the tag into it, and save. See BigCommerce’s help on scripts.

<script async data-domain="example.com" src="https://fiveb.ar/js/tally.js"></script>

Where your store asks visitors to consent to cookies, BigCommerce holds back scripts in the Analytics category until they accept. Choose the category that fits your store’s own policy.

Once it’s live, check it works.
