Great App! Able to change title listing is a major plus to help with SEO on Google Shopping, much better than the native shopify integration!

We used the Nabu app to make bulk corrections to apparel product variants which had previously been tedious to correct in GMC.

Frequently Asked Questions (FAQs)

Can I display my reviews on other marketplaces?
No. This integration supports Google Shopping only and is not available for other marketplaces.
Is there any fee/cost associated with integrating Stamped.io with AdNabu?
No, there are no additional fees for using this feature. However, this feature is available for ‘Advanced’ and ‘Plus’ users only.
What is Google’s Product Rating Policy?
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.
How long does it take for the reviews to start displaying on my product listings?
After both the product and review feeds are submitted to GMC, Google may take up to 14 days to review, approve, and display product ratings.
How long does the whole process of integration take?
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 the 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).
What other Product Review apps are available for integration?
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.
How do reviews appear in multilingual and multicurrency Google Shopping feeds?
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.
What if my products don’t have identifiers like MPNs or GTINs?
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.
