Within the local SEO ecosystem, Google reviews are essential for building trust. Consider it this way: when was the last time you made a reservation at a restaurant without first checking its rating on Google and reading the customer comments? The same principle applies to all types of professionals—healthcare providers, attorneys, architects, and even tourist destinations when you want to determine whether a visit is worthwhile.
However, over the course of the past year, thousands of business owners have observed something unusual: their ratings… are vanishing without any prior notice. Is this a system error or a deliberate strategy? A recent study by the SEO tool GMBapi, entitled “Deleted Google Reviews: AI vs. Legal Removals”, sheds light on this quiet digital purge.
AI Under Suspicion
The study examined data from tens of thousands of commercial establishments between January and July 2025, revealing a significant variance across markets. In English-speaking countries (United States, United Kingdom, Canada, and Australia), the primary cause of this disappearance is overreach by artificial intelligence. Google has trained its algorithms to combat review farms and fraudulent feedback, but the result has been substantial collateral damage.
Google’s artificial intelligence is removing legitimate five-star reviews by mistakenly categorizing them as spam. Factors such as posting from a public WiFi network, unusual activity on a user’s profile, or the use of overly generic phrases are triggering system alarms. According to GMBapi, this is distorting business realities: as their most favorable reviews disappear, their online reputations may be negatively affected, not due to poor service but as a result of an overly cautious algorithm.
As the study’s authors explain, “Positive reviews that sound too similar or come from accounts with little prior activity are more likely to vanish, even when they’re real.”
The Retroactive Effect and an Overwhelmed Google
A critical detail highlighted by the study is that this cleansing does not only impact recent opinions. In industries such as hospitality and retail, Google is conducting a retroactive cleanup, removing reviews that are more than two years old. This indicates that the algorithm has learned to reevaluate what appears suspicious and is now auditing the history of businesses.
Furthermore, the report emphasizes a preventive bias in sensitive sectors: in the medical category, for instance, more than 50% of deleted ratings are five-star reviews, demonstrating that the artificial intelligence is extremely skeptical of excessive positivity in regulated fields. This aggressive approach has resulted in a tangible operational consequence: Google itself has acknowledged that its appeals systems are overwhelmed, with response times extended due to the massive influx of business owners attempting to recover their lost reviews.
The Curious German Case: The Law Versus Opinion
While the root of the problem is technological in the Americas, in Europe—specifically Germany—the cause is legal. The study notes that Germany has become a global anomaly due to its strict laws against defamation and the protection of personal rights.
There, a whole new sector of legal service providers has emerged—companies hired by business owners to force the removal of negative reviews (one- and two-star ratings). In an effort to avoid expensive legal penalties, Google frequently complies with these requests. This situation creates a hazardous scenario: a review profile that does not reflect authentic customer experience but instead represents a business’s financial capacity to pay for legal support to “clean” its image.
As one German user explained on Google Maps’ own support service:“I have been a local guide for many years now, but I am starting to look elsewhere. To me, ratings and reviews are becoming increasingly useless, because any complaint against a rating invariably leads to it being taken down, no matter how baseless the claim is. And there does not seem to be any usw in appealing the decision.
Case in point: a three-star rating of me without any text was taken down for “libel”. But this isn’t the only case, by far. Any review that isn’t a glowing five-star one is apparently libelous. If it isn’t possible to give three stars, what is even the point of all of this?”
The authors of the study further comment: “2.19% of all reviews (in Germany) have been deleted since July 2024, with deletions surging after March 2025. Most of the removed reviews in Germany were low-rated, and nearly all disappeared within 50 days of posting. Among the businesses we support with reputation management, 13% of all 1-star reviews have been deleted.”
Consequences for Consumers and Businesses
Within this context, the reliability of Google’s local search is at stake. If positive reviews vanish in error and negative ones are erased due to legal pressure, the average rating ceases to be a useful metric.
For business owners, the strategy has shifted. It is no longer sufficient to merely solicit reviews; monitoring them has become essential. The loss of user-generated content directly affects search rankings, since keywords within reviews are a vital ranking factor.
