What is Google Analytics, and why should I enable it?
Google Analytics is a service provided by Google for analyzing traffic on your website. It can track how people found your site and how they explored it.
To use Google Analytics on your Zazzle Store, go to your store's "Settings" page and click "Advanced Settings". On that page, check the box labeled "Enable Google Analytics".
If you already have a Google Analytics account, you can enter your Google Analytics ID in the field labeled "Google Analytics Tracking ID (UA-XXXXXX-X)".
If you don't have a Google Analytics account, get one here for free: https://www.google.com/analytics/
Cross-domain Tracking
There is an optional checkbox to enable cross-domain tracking. Check this box only if you are using the same Google Analytics ID on a website that points to products in your Zazzle Store. This will ensure that Google will track traffic from your own website as well as your Zazzle Store. If you do not use Google Analytics on a website outside of Zazzle.com, you do not need to check this box.
