Google recently gave every site displaying star ratings a specific reason to audit its review markup. On July 24, Google updated its review snippet structured data documentation to prohibit fake and undisclosed incentivized reviews.

The updated guidelines apply to reviews displayed on the page and included in its structured data. Google specifically identifies two types of prohibited review content:

• Reviews that aren’t based on a genuine experience with a product or service
• Reviews written in exchange for money, discounts, vouchers, free products, or other benefits without clear and prominent disclosure

Google warns that violating its review snippet guidelines may lead to a manual action. If that happens, the affected page can lose eligibility for review rich results. That means its stars and other review enhancements may disappear from search results.

However, a structured data manual action doesn’t directly affect how the page ranks in standard Google Search results. The page may still appear, but it won’t remain eligible for the affected rich result.

Review Markup Isn’t a “Set It and Forget It” Task

Many sites still treat review markup as a one-time technical project. A developer adds AggregateRating structured data, the stars begin appearing, and nobody checks whether the reviews remain compliant.

That approach poses a risk because Google expects structured data to reflect the content users can see on the page. The reviews and ratings included in the markup must match the visible review content.

If a page displays suspicious five-star reviews collected through a free-sample campaign, the incentives must be clearly disclosed. Hiding that information in a general terms page doesn’t meet Google’s requirement for clear and prominent disclosure.

Google’s general structured data guidelines also prohibit misleading markup, including fake reviews. Even a technically valid schema can violate Google’s quality guidelines.

How to Audit Review Snippet Structured Data

Start by identifying every page that uses Review or AggregateRating structured data. Then check whether the visible content and markup follow Google’s requirements.

Ask these questions during the audit:

• Are the reviews based on genuine experiences?
• Were reviewers offered money, discounts, vouchers, rewards, or free products?
• Is any incentive disclosed clearly and prominently with the review?
• Does the rating shown in the structured data match the visible rating?
• Can users easily find the marked-up reviews on the page?
• Does each review apply to a specific product, service, or other eligible item?
• Does the aggregate rating accurately represent the reviews shown?
• Are reviews or ratings being copied or aggregated from another website?

Google recommends accepting ratings that include a review comment and the author’s name. Although that isn’t a strict requirement, it gives users more context and makes the rating easier to evaluate.

After correcting the markup, test representative pages with Google’s Rich Results Test. You should also inspect affected URLs in Search Console and monitor the Manual Actions report.

Keep in mind that the Rich Results Test primarily identifies technical errors. It might not catch authenticity problems, undisclosed incentives, or other quality violations.

Incentivized Reviews Require Clear Disclosure

Google isn’t banning every incentivized review. It prohibits incentivized reviews that don’t clearly and prominently explain what the reviewer received.

If your business collected reviews through a rewards program, discount campaign, giveaway, or free-product offer, the disclosure should appear with the review. Users shouldn’t have to visit another page or search through the site’s terms to discover the relationship.

Businesses should also avoid influencing the reviewer’s opinion. A campaign that only rewards positive reviews creates a much larger trust problem than a program that requests honest feedback regardless of the rating.

Don’t Aggregate Ratings from Other Websites

Sites that import third-party reviews need to pay especially close attention. Google’s review snippet guidelines say not to aggregate reviews or ratings from other websites.

For example, a site shouldn’t combine ratings from several external review platforms and mark the resulting score with AggregateRating structured data.

Local businesses and organizations face another limitation. When an entity controls the page displaying reviews about itself, pages using LocalBusiness or Organization Structured data isn’t eligible for Google’s star review feature. That restriction can apply even when the reviews appear through an embedded third-party widget.

A review widget may still be useful for visitors, but displaying reviews on a page doesn’t automatically make those ratings eligible for review snippet markup.

What Happens After a Manual Action?

If Google applies a structured data manual action, the structured data on the affected page may be ignored. The page can still appear in ordinary search results, but it may lose its review stars and other rich-result features.

Google directs site owners to use Search Console’s Manual Actions report to identify the problem. After removing the noncompliant content or markup, the site owner can submit a reconsideration request.

That cleanup may require more than editing the schema. If the underlying reviews are fake, improperly aggregated, or missing required disclosures, the visible page content must also be corrected.

If your team doesn’t have the bandwidth to conduct a proper audit, consider getting outside help with your SEO compliance before a preventable markup issue leads to lost search visibility.

The Bottom Line

This isn’t a major algorithm update. Google has strengthened its documentation on behavior that was already risky, making the potential consequences clearer.

Sites with genuine reviews and prominent incentive disclosures shouldn’t need major changes. Everyone else should audit both the visible review content and its structured data now.

Getting the schema technically correct is only half the job. The reviews behind those stars must also be authentic, transparent, visible, and eligible under Google’s guidelines.
