Collect Google Customer (Merchant) Reviews after checkout

Learn how to collect Google Customer (Merchant) Reviews on your Shopify store using the Reputon checkout extension. Step-by-step setup guide for the Thank You and Order Status pages.

The review request appears on the Thank You and Order Status pages right after a customer completes their purchase. Customers who rate you 5 stars are invited into the Google Customer Reviews program, which builds your Google Seller Rating over time.

What is Google Customer Reviews?

Google Customer Reviews is a free tool from Google that helps you collect customer feedback after a purchase. If a customer opts in, Google sends them a short survey email once their order is delivered, asking how their shopping experience went.

Benefits of Google Customer Reviews

1. Stars in your Google Ads. Once you hit 100 reviews, Seller Rating appears automatically in your search ads. Same budget, higher click-through rate. Competitors without it look less credible next to you.

2. Stars in Google Shopping. When someone clicks a product in the Shopping tab, your store rating shows right next to the store name. At the moment of comparison, you win on trust before they even read the product page.

How the review flow works

After setup, every customer sees a star rating widget on the Thank You and Order Status pages. What happens next depends on the rating they choose.

What the 5-star opt-in looks like

If 5 stars are selected, customers are redirected to the confirmation page with an option to opt in to the Google Customer Reviews program.

Customers who opt in will be sent an email managed by Google, asking them to rate their experience. This rating is then aggregated to become the Seller Rating.

The Google survey email

Customers who opted in receive this email from Google after their delivery date. Completing the survey is what creates the actual Seller Rating for your store:

What the 1–4 star feedback form looks like

Customers who rate 1–4 stars see your custom feedback form instead. Their message goes to your Reputon dashboard so you can follow up privately, it does not get posted publicly anywhere.

Reading your dashboard

The dashboard counts widget clicks - not completed Google reviews. A "click" is recorded every time a customer selects a star rating, regardless of whether they opted in to the survey or completed it.

Your Reputon dashboard tracks every interaction with the widget. Here's what the numbers actually mean:

Here’s how it works:

• A customer clicks the widget and selects a star rating.

• If they select 5 stars, they are redirected to the Google opt-in step.

• If they select 1–4 stars, the feedback form opens.

• All clicks are still tracked in the dashboard, regardless of whether a final review is submitted.

How to test if everything is working

1. Check the "Thank You" page

• Go to the Thank You page and click on the 5-stars.

• If everything is fine, the Google Customer Reviews popup will appear as in the example below.

2. Create a test order

• Create a test order in your store checkout.

• Use a real email address you can access.

• Pay with Shopify test mode or a real payment method you can refund.

• On the Thank You page, find the Rate Us widget.

• Click the 5 stars to confirm the popup appears.

3. Check Google Merchant Center

• Wait 24-48 Hours for data to appear.

• Go to Google Merchant Center → Reviews.

• Look for “Survey Opt-ins Received” and “Surveys Offered“.

• Data typically appears within 2 weeks.

Common questions

Opt-in button doesn’t show on the Thank You page

• Make sure the Google Customer Reviews is added in your Google Merchant Center.

• The Google Merchant ID used matches your store domain and entered correctly.

• No ad blockers are used.

I don't see reviews in Google Merchant Center

• Wait for 24-48 hours for initial data to appear

• Check if your Merchant Center account is properly set up

• Check if your store meets Google’s review program requirements

I don't have a Google Merchant ID. Can I still use the checkout extension?

Yes, but without a Merchant ID, the Google Customer Reviews opt-in won't appear. The widget will still show the star rating and your custom feedback form for all ratings. So you can collect private feedback from customers, but the Seller Rating program won't be activated.

How many days should I set for Average delivery days?

Set this to your typical delivery time. For most stores, this is 5-14 days.

Google uses this number to time the survey email so it arrives after the customer has received their order. For digital products (downloads, subscriptions), set this to 1.

Why does my dashboard show clicks but I don't see new Google reviews?

There are several steps between a widget click and a published Google Seller Rating:

• The customer must select 5 stars and click "Yes, send me the survey" on the opt-in popup

• Google sends the survey email only after your set delivery days have passed

• The customer must open and complete the email survey

• Google aggregates ratings, you typically need 100+ survey responses before a Seller Rating badge appears on your ads

This is all normal. Dashboard clicks will always outnumber published ratings. The click count shows interest, not completions.
