Google recently revised its review snippet structured data documentation to stress that sites must not include fake or undisclosed incentivized reviews in their markup. The change — reported by Barry Schwartz on Search Engine Land — reinforces the importance of transparency when collecting and displaying user reviews.

Review snippets are short excerpts or aggregated ratings that can appear in Google’s rich results and knowledge panels. Google’s update explicitly tells site owners: “Don’t include fake or undisclosed incentivized reviews on your page or in your structured data markup.” This guidance is designed to prevent deceptive practices that could mislead search users and distort trust signals.
This change raises the compliance bar for anyone using review markup. Sites that have relied on incentivized review programs without transparent disclosure should re-evaluate and update their approach. Beyond markup eligibility, Google’s emphasis on authenticity affects overall trust signals: genuine reviews contribute to credibility and better user experiences, while deceptive reviews can cause long-term reputation damage.
To quote the Search Engine Land summary of the update: “Google updated the review snippet structured data guidelines with a new guideline that reads, ‘Don’t include fake or undisclosed incentivized reviews on your page or in your structured data markup.’” — Barry Schwartz, Search Engine Land
Google’s developer documentation reinforces the same point: “Don’t include fake or undisclosed incentivized reviews on your page or in your structured data markup.” — Google Developers
An incentivized review is feedback provided in exchange for compensation, including discounts, free products, vouchers, or other benefits. If an incentive is provided, it must be clearly disclosed.
Non-compliant reviews can lead to the removal of review snippets in search results and damage to site credibility. In some cases, persistent abusive practices could harm visibility.
Google’s documentation update makes the rules around review snippet markup clearer: focus on authenticity and transparency. Audit your review collection, disclose incentives when present, and only mark up reviews that reflect genuine user experiences to maintain eligibility for review snippets and preserve user trust.
