Should you mark up reviews if you can’t guarantee they’re genuine?

No. If you cannot stand behind a review as real, do not mark it up. Google’s review snippet guidelines say: “Don’t include fake or undisclosed incentivized reviews on your page or in your structured data markup.” Markup turns a review into a claim Google may display under your listing, so an unverified review becomes an unverified claim in the search results.
The rules that decide what you can mark up
| Rule in Google's guidelines | What it rules out |
|---|---|
| Review content must be "readily available to users from the marked-up page" | Ratings that exist only in the code |
| An aggregate rating must be visible on the page | A star average shown to Google but not to visitors |
| Reviews must be about "a specific item, not about a category or a list of items" | One rating stamped across a category page |
| "Don't aggregate reviews or ratings from other websites." | Copying star averages from a directory or marketplace into your markup |
| A business that controls reviews about itself cannot get the star feature on its LocalBusiness or Organization pages | Marking up testimonials about your own company on your own site |
| For local businesses, "Ratings must be sourced directly from users." | Editor-curated ratings presented as customer ratings |
That last pair matters for service businesses. Reviews you collect about your own company, even real ones, are ineligible for the star feature on your own business pages. Real product reviews on a product page are a different case and can qualify.
Where third-party review platforms fit
A review platform’s widget on your page does not change Google’s rules. If the reviews are about your business and you control what appears, the self-serving restriction applies. If the widget pulls a rating from another site, the rule against aggregating reviews from other websites applies. Check Google’s guidelines first and the platform’s instructions second.
What happens when markup breaks the rules
Google’s structured data policies require markup to represent the page’s actual content, and they say a structured data issue can result in a manual action. Such an action removes the page’s eligibility for rich results, so the stars disappear; the policies add that it does not change how the page ranks in web search. Google’s handling of markup it does not trust goes beyond reviews, as why Google ignores schema it considers spammy shows.
An audit before you mark anything up
- Can you trace each review to a real customer and a real purchase or visit?
- Is the review visible on the page you are marking up?
- Is it about the specific product or service on that page?
- Was it written without an undisclosed incentive?
Mark up only the reviews that pass all four. If none do, leave review markup off; the reviews can still appear on the page for visitors without being presented to Google as rating data.
