Important: Opt-in integration is a required step for Google Customer Reviews. The program won’t work on your site and surveys will not be offered unless this step has been completed. The opt-in integration lets Google display the Google Customer Reviews opt-in on your site and offer surveys to customers who have opted in to the program.
Before getting started, verify that you have reviewed the Google Customer Reviews policies and completed the integration requirements for the opt-in:
Your shopping cart and checkout pages must be hosted on the same domain
The confirmation page must be hosted on your own domain
must be added to the top of every webpage
Once verified, follow the integration instructions to add the code snippet below to your order confirmation page and customize the variables as needed. The snippet integration will allow Google to display the Google Customer Reviews opt-in on your website.
