Why the Update Matters
As eCommerce advertisers and feed managers, we’ve long known that review-incentivisation is a tricky area. On the one hand, offering a coupon or reward to a customer to leave feedback can boost your review volume; on the other hand, it has historically run up against policy concerns. Platforms like Trustpilot, among others, prohibit compensated reviews without transparent disclosure.
Now, Google has clarified its stance: reviews gathered via incentives such as gift cards, points or discounts are allowed, provided they’re properly identified using the new attribute in the Product Review Feed. According to Google’s schema, the attribute is (type: xs:boolean).
This means: you don’t have to shy away from incentives; if you use them and want them represented in your review feed, you must follow Google’s rules exactly.
What the Schema Says (and Why It Matters)
Let’s get technical, because your feed setup depends on exact compliance. The key references are:
- The official “Product Review Feeds” overview by Google.
- The XML schema reference, which includes the <is_incentivized_review> attribute.
- The policy help article: “If you provide an incentive for a review, you are required to use the <incentivized_review> attribute in your feed to disclose it properly.”
What the attribute means
- Attribute Name: is_incentivized_review (boolean)
- Optional, but conditional: if any review is incentivised, you must set this to true for that review.
- Clear implication: you must separately identify when a review was collected via a reward or incentive.
Why we care
- Google matches product reviews in your feed with your products in Merchant Center and can show stars, review counts and review content in Shopping ads and free listings. If your feed is incomplete, inaccurate, or hides incentivised reviews, you risk suppression or disapproval of your review feed.
- Since we manage high volume and complex feeds across clients, mis-tagging this could damage visibility for your accounts.
Implementation Checklist: How to Add is_incentivized_review
Here’s how I’d advise you (and your clients) to integrate this attribute into your review feed process:
- Identify which reviews are incentivised
- If you offered a coupon, gift card, reward points or other compensation specifically in exchange for a review, mark the review as incentivised.
- If you didn’t offer anything, set
is_incentivized_review=false(or omit the attribute if not applicable). - Also, check legal/regulatory requirements in your country—some jurisdictions may have stricter rules around incentivised reviews.
- Update your feed mapping / aggregator settings
- If you’re using a review aggregator or plugin (for Shopify, WooCommerce, etc), ensure it supports this attribute.
- Map your “was this review incentivised?” field to
is_incentivized_review. - Example: in a WooCommerce Google review plugin, you may need to add a custom field to track incentives. (See e.g., Webtoffee guide)
- Ensure your XML feed includes valid syntax (boolean:
trueorfalse). For example:
<review>
<product_id>12345</product_id>
<review_id>r98765</review_id>
<reviewer>Jane Doe</reviewer>
<review_date>2025-11-18</review_date>
<review_rating>5</review_rating>
<review_text>Great product!</review_text>
<is_incentivized_review>true</is_incentivized_review>
</review>- Ensure complete coverage of reviews
- You must submit all reviews, positive, negative, and incentivised. Google’s policy emphasises transparency.
- Do not exclude low-star reviews or hide them simply because they were incentivised.
- Schedule your feed refreshes
- Google requires your review feed to be updated at least monthly (some implement weekly/daily for freshness). If you have incentives running, make sure your feed refresh includes those reviews soon after fulfillment.
- Monitor diagnostics in Merchant Center
- After uploading the feed, check for errors/warnings around the incentivised review attribute or other review feed issues.
- If Google finds a pattern of mis-tagging or hidden reviews, there’s a risk of feed suppression.
Best Practices & Caveats (From My 15 Years of Shopping/Feed Work)
Here are some practical tips based on experience running high-volume Google Merchant Center and Shopping feeds:
- Be honest and transparent: If you offered a coupon for a review, mark
is_incentivized_review=true. Trying to hide it may result in review feed problems or worse. - Segment review flows: If you use different review collection flows (paid incentive vs. organic), tag them accordingly to ensure clean data and better attribution.
- Legal/compliance check: Depending on the country (for example, some EU and US states), incentivised reviews may be regulated (e.g., “material connection” must be disclosed). Google’s tool does not replace your legal compliance obligations.
- Measurement & attribution: Use UTM parameters (in your review URLs) or internal flags to track how incentivised reviews affect performance, sentiment, conversion rates, etc.
- Avoid incentive bias: If too many reviews are incentivised, you risk skewed review sentiment (tending to be very positive). That may raise flags or reduce credibility. Combine with organic reviews wherever possible.
- Maintain review authenticity: Incentives should not compromise the authenticity of feedback; don’t force 5-star reviews to game the system. Google checks for patterns.
- Communicate with your aggregator/platform: If you’re using a SaaS review aggregator for your clients (or you act as the aggregator for your clients), ensure their feed output supports the
is_incentivized_reviewtag and they manage the mapping. - Document your process: Internally record which reviews were incentivised and how they were tagged, and integrate this into your monthly feed-refresh logs/spreadsheet (e.g., the one you use to track Google Shopping data improvements).
What This Means for Your Clients’ Shopping Campaigns
For eCommerce merchants, especially those you consult with, this change gives more flexibility. Suppose your client offers a “review & get 10% off next purchase” programme (or similar). In that case, you no longer need to worry that this automatically violates Google’s review policy, provided you tag the review feed correctly. That can increase review volume, which in turn can improve trust signals, conversion rate, and visibility of review stars in Shopping.
However, offering incentives without tagging them is a risk. Mis-tagged reviews might lead to suppressed review stars or even review feed rejection, reducing the visibility and credibility of product listings.
In your role as Google Shopping consultant and feed expert, this update gives you another lever to pull for your clients. But it also places responsibility: you must update docs, feed processes, and client onboarding checklists to reflect this attribute and ensure compliance.
Summary
- Google’s Product Review Feed schema now includes the optional boolean <is_incentivized_review> attribute for reviews collected via incentives.
- If you offer incentives (gift cards, coupons, points) for reviews, you must mark those reviews in your feed.
- Maintain full transparency by submitting all reviews (incentivised and organic) and by updating your feed mapping accordingly.
- Use this as an opportunity to boost review volume for your clients, just ensure everything is tagged correctly and compliant.
If you’d like a feed-template (XML or CSV) that already includes the is_incentivized_review field, let me know, I can draft one aligned with Google’s schema and your typical client setup.
