This article explains how to install a Google customer review module.

The Google Customer Review module works using a opt-in step. One time per customer, an offer to participate in the Google Customer Reviews program is displayed. If they signup, they receive a one-time email from Google to provide a review about your business after they make a purchase. See Google Customer Review Surveys for more information.

Google returns the reviews in the optional Google Customer Reviews badge, in the Google Merchant Center dashboard and as seller ratings (stars / reviews on Google Shopping and advertisements).

Optional Badge integration

You can add a badge on your site to display your favourable rating to your customers. However, if there aren’t any seller ratings available, the message "no rating available" will appear. See the prerequisites in this article more information.

   <script src="https://apis.google.com/js/platform.js?onload=renderBadge" async defer></script>
   <script>
   window.renderBadge = function() {
   var ratingBadgeContainer = document.createElement("div");
   document.body.appendChild(ratingBadgeContainer);
   window.gapi.load('ratingbadge', function() {
   window.gapi.ratingbadge.render(ratingBadgeContainer, {"merchant_id": XXXXXXXXX, "position": "YYYYYYYYY"});
   });
   }
   </script>

2. In your eCom Back Office, click Settings > Web extras.
3. Scroll to the JAVASCRIPT section and paste the code snippet.
4. Change the merchant_id (XXXXXXXXX) to your own code. This can be found in the original code snippet added in the TRACKING section.
