Google updates review snippet guidelines: fake or undisclosed incentivized reviews must not be marked up

Google has updated its official documentation for review snippet structured data, adding a clear directive: site owners must not include fake or undisclosed incentivized reviews on their pages or in their structured data markup. The change, published on July 24, 2026, reinforces the company’s long-standing quality guidelines and directly impacts any site that uses review markup to appear in Google Search rich results.

Review snippets are short excerpts of reviews or ratings that appear in search results, often as an average star rating from multiple reviewers. They can also appear in Google Knowledge Panels. The updated documentation now includes a new guideline that reads: “Don’t include fake or undisclosed incentivized reviews on your page or in your structured data markup.” While the rule may seem obvious, Google’s decision to spell it out explicitly signals that the issue is becoming more common or that enforcement is tightening.

Examples of prohibited reviews

Google provided concrete examples of reviews that should not be marked up with structured data. These include:

• Reviews written by someone who did not actually use the product or service.
• Reviews that were incentivised (e.g., paid or given free products) without clear disclosure.
• Reviews written by employees posing as genuine customers.
• Reviews posted by competitors or people with a conflict of interest.

Any markup that includes such reviews may result in the site losing eligibility for review snippets in Google Search. The examples are identical to the types of fake or undisclosed reviews that Google has long prohibited in its general content policies, but the new structured data guideline makes the rule explicit for developers and SEOs.

Why this update matters for Indian businesses

For Indian e-commerce platforms, local directories, and sites that aggregate user reviews, this update is a direct reminder to audit their review collection and markup practices. The Indian market has seen a rapid growth in online reviews, especially for local businesses, travel, and hospitality. Many sites use structured data to display star ratings in search results, which can improve click-through rates and trust.

However, if a site unknowingly includes reviews obtained through undisclosed incentives or from fake accounts, it risks being flagged by Google and losing the rich result feature entirely. This is especially relevant for businesses that run review-gathering campaigns offering discounts or freebies without proper disclosure. The new guideline does not ban incentivised reviews outright, but it requires that any incentive must be clearly disclosed, and the review must still be genuine.

What SEO professionals should check next

Search Engine Land, which first reported the update, notes that Google added the guideline for a reason — likely because the search engine is seeing more sites using these techniques to inflate ratings. SEO professionals in India should:

• Review their structured data markup to ensure every review entry corresponds to a real user who experienced the product or service.
• Remove any reviews that were obtained through undisclosed incentives, such as “review for a discount” campaigns where the incentive was not mentioned.
• Check employee or competitor reviews — if any are present, they must be removed from markup.
• Add explicit disclosure text near any review that was incentivised, even if the incentive is small.

The update applies to all review snippet markup, including the common `Review` and `AggregateRating` schema types. There is no grace period mentioned; Google’s guidelines are typically enforced algorithmically and through manual actions.
