Google updated its review snippet structured data documentation on July 24, 2026, adding explicit language that prohibits fake and undisclosed incentivized reviews from appearing in page content or structured data markup. The change was noted in Google Search Central’s documentation changelog and picked up across Search Engine Land, Search Engine Journal, and Search Engine Roundtable on July 27.

What Changed

The updated guidelines now state two categories of prohibited reviews:

  1. Reviews that are not based on a genuine product or service experience
  2. Reviews written in exchange for money, discounts, vouchers, free products, or similar benefits — unless that incentive is clearly and prominently disclosed

Crucially, Google attached an enforcement warning that was not previously there: “If your site violates one or more of these guidelines, then Google may take manual action against it.”

Google has not published a separate blog announcement, but the language now sits inside the formal requirements for review snippet rich result eligibility on Google Search Central.

What This Means for SEOs

Any site using Review or AggregateRating structured data needs to treat this as a compliance issue, not a best-practice suggestion. The manual action warning is explicit and significant.

The change brings review snippet rules in line with Google Business Profile review policies, which have long prohibited incentivized reviews. This is not Google inventing a new concept — it’s codifying an existing standard into structured data requirements and attaching enforcement teeth to it.

For affiliate and product review sites especially, the risk is real. Many use “get a free product in exchange for an honest review” programmes. Those reviews are now explicitly disqualifying if the incentive is not clearly disclosed on the page where the review appears — not buried in a terms and conditions page or mentioned in an email to reviewers.

What to Do Now

  • Audit your review structured data. If you use Review or AggregateRating schema, inventory where those reviews came from. Any review generated through a gifting, discount, or compensation programme must include on-page disclosure.
  • Check your disclosure language. Disclosing in the footer, a separate FAQ, or via email to reviewers will not meet the standard. The disclosure needs to be visible alongside the review itself.
  • Remove or fix non-compliant reviews. If you have reviews in structured markup that cannot be verified as genuine or properly disclosed, remove them from the schema. Losing rich result eligibility is far preferable to a manual action.
  • Monitor Search Console. Check the Manual Actions report and the Rich Results status report. If Google has already flagged your site, the Search Console report will show it.

This is not a wait-and-see situation. If your site has structured data that includes incentivized reviews, the exposure is live from the moment Google recrawls those pages.
