Google added a new line to its review snippet structured data guidelines on Friday: “Don’t include fake or undisclosed incentivized reviews on your page or in your structured data markup.” The addition covers the Review and AggregateRating schema types that feed the star ratings and excerpts shown in rich results and Knowledge Panels. Barry Schwartz reported the change for Search Engine Land.
The word to isolate is “undisclosed.” Google did not prohibit incentivized reviews. A brand that offers a discount, a voucher, or a free product in exchange for a review can still mark that review up with structured data, provided the incentive is disclosed clearly and prominently on the page. Strip every incentivized review from your markup on reflex and you will remove content that was already compliant.
Google paired the new line with two worked examples of what does not qualify for review snippet eligibility. The first: “Reviews that aren’t based on a genuine experience of a product or service.” The second: “Reviews written in exchange for a benefit (such as money, discounts, vouchers, or free products) that don’t clearly and prominently disclose the incentivization.” Read together, the two examples separate two distinct failure modes: reviews that are fabricated outright, and reviews that are real but hide the arrangement that produced them.
That second category is the one most sites will actually have to fix. A fake review is a binary problem: it should not exist in the markup at all. An undisclosed incentive is a labeling problem, and labeling problems have a labeling solution. Adding a visible disclosure line next to an incentivized review, rather than deleting the review, is very often the correct remediation.
Google’s documentation gives no enforcement date and no stated penalty mechanism for this change. There is no announced manual action tied to the guideline, and Search Engine Land’s coverage does not report one. The practical risk is narrower and more specific: losing eligibility for the review snippet rich result and the associated Knowledge Panel treatment, not a ranking penalty applied to the page itself.
Search Engine Land’s assessment is that Google most likely wrote the guideline because it is seeing the technique in the wild: reviews collected through payment or discount and then marked up without any disclosure to the reader or to Google. Google has published incentivized-review guidance in its general review policies before. Folding it explicitly into the structured data documentation signals that the company now treats disclosure as a markup-eligibility condition, not just a general best practice.
Any team that marks up incentivized reviews with structured data should audit that markup this week, not to purge incentivized content, but to confirm each one carries a clear, prominent disclosure of the benefit exchanged. Sites that run review-collection programs through discounts, vouchers, or free products should check the actual disclosure language against what a reader would notice at a glance, since “clearly and prominently” is Google’s stated bar and a footnote buried in terms of service will not meet it.
