Can I use an analytics script on my site such as Google Analytics, or Google Tag Manager?

PRESSERO > *Pressero FAQs
Yes, you may insert an analytics script in a B2C site in Sites > Site name > Settings > SEO/HTML tab in the "Edit Analytics Script" area and the "Edit Checkout Conversion Analytics Script" area.

*** Please note - Manually inserting analytics scripts via the HTML Head Content section or via a custom skin should not be done. Analytics scripts should only be inserted in the two analytics sections.  Checkout analytics are generated by the Pressero system based on the script you add here.
