Question 1

How do I initiate the AdNabu–Stamped.io integration, and what happens in the backend?

Accepted Answer

Start by making sure all your Shopify products and variants include unique identifiers such as GTINs or MPNs. Google relies on these to match reviews with the right items in your feed. Without them, reviews may not display correctly.

Next, check that your store is subscribed to AdNabu’s Advanced Plan. If you are not on this plan, please upgrade before continuing with the setup.

After that, in AdNabu, navigate to Settings → Integration → Product Reviews. For Item IDs, select ‘Use the default product ID format (shopify_{country}{product_id}{variant_id})’. For Group IDs, select ‘Use SKU as group ID format.’ Note that this setting will update all item group IDs in your Shopping feed to SKUs.

After that, enable Google Product Ratings in Stamped.io. Open the Stamped.io app in Shopify, go to Settings → Google Integrations, and enable Google Product Ratings. For more details about this step, please refer to this Stamped.io help page.

Finally, create a support ticket from the Product Review section in AdNabu by clicking Generate. This opens the Google Shopping Integration – Product Reviews form. Fill in your email address, Shopify store URL, select Stamped.io as your review platform, and add notes if needed. Submit the form once complete.

Once submitted, AdNabu will share the product feed, and Stamped.io will share the product review feed to Google Merchant Center. Google will then take up to 14 days to review, approve, and map both feeds. Once that’s done, verified star ratings and review counts will automatically begin appearing on your listings.

Question 2

Which type of reviews will the integration display on Google Shopping ads?

Accepted Answer

The integration shows only verified, product-specific reviews collected through Stamped.io. These appear as aggregated star ratings (1–5) along with the total number of reviews.

Question 3

Can I choose which product reviews appear on my listings?

Accepted Answer

No. Only Google can decide which reviews to display on your listings. Merchants cannot pick or prioritize individual reviews for Shopping ads or listings.

Question 4

How are reviews matched to the product(s)?

Accepted Answer

Google maps reviews to the right products in Merchant Center using unique identifiers such as GTINs, MPNs, etc.

Question 5

Can I display my reviews on other marketplaces?

Accepted Answer

No. This integration supports Google Shopping only and is not available for other marketplaces.

Question 6

Is there any fee/cost associated with integrating Stamped.io with AdNabu?

Accepted Answer

No, there are no additional fees for using this feature. However, this feature is available for ‘Advanced’ and ‘Plus’ users only.

Question 7

What is Google’s Product Rating Policy?

Accepted Answer

Google’s Product Ratings program lets merchants show aggregated star ratings (1–5) and review counts in Shopping ads and free listings. To qualify, you need at least 50 valid product reviews, and your product data must include accurate identifiers such as GTINs or MPNs. In addition to that, your product reviews must also meet Google’s content policies to be eligible to appear in listings.

Read more about the policy on this official Google help page.

Question 8

How long does it take for the reviews to start displaying on my product listings?

Accepted Answer

After both the product and review feeds are submitted to Google Merchant Center, Google may take up to 14 days to review, approve, and display product ratings.

Question 9

How long does the whole process of integration take?

Accepted Answer

The integration process is quick and usually takes less than a few minutes, apart from the time you spend filling out our Product Review Integration form.

Once you configure the product ID and group ID settings within AdNabu, your product feed in Merchant Center updates almost instantly with the new group IDs.

After that, when you enable Google Product Reviews in Stamped.io, it sends the product review feed to Merchant Center. From this point onward, Google takes over the approval and mapping process, which may take its own time (up to 14 days, as discussed earlier).

Question 10

What other Product Review apps are available for integration?

Accepted Answer

Along with Stamped.io, AdNabu integrates with Judge.me, Loox, Opinew, Okendo, Automizely, Yotpo, and Fera.ai.

If you use a different review app, please contact support@adnabu.com. Our team will review your request and try its best to ensure that AdNabu integrates with the specific product review aggregator app you are using.

Question 11

How do reviews appear in multilingual and multicurrency Google Shopping feeds?

Accepted Answer

The way product reviews and ratings are displayed to users is controlled entirely by Google’s systems. Merchants cannot influence their language or format.

In general, reviews are displayed in the local language, for example, 3.6 (85 avis d’utilisateurs) in France.

However, in some regions, Google may only show star ratings and total review counts without text. The presentation can vary by country, market, or even individual users, and there is no way to predict the exact format.

Question 12

What if my products don’t have identifiers like MPNs or GTINs?

Accepted Answer

Custom products don’t have standard identifiers, such as GTINs or MPNs. These identifiers are required for Google to match reviews with the correct products. Without them, reviews may not display, and the AdNabu–Stamped.io integration will not work as expected.

To avoid this, assign valid and available identifiers (such as SKUs) to all possible items.
