The loss persisted even after Yelp's warning banner was removed, with no sign of recovery 18 months later. *By Barbara Castiglia, originally published in Modern Restaurant Management on 2026-10-27.

For a new working paper, accounting professor Yi Cao and his co-authors tracked businesses that Yelp publicly flagged for buying reviews or offering perks in exchange for five stars. They matched those flags against foot-traffic and credit card data finding that, once flagged, businesses lost an average of eight percent of their foot traffic compared with similar businesses nearby, and card spending fell with it. Yelp’s warning banner comes down after 90 days, but the data found customers didn’t return. Eighteen months later, those businesses were still down, with no sign of recovery because customers had moved on to other businesses. This hit is even steeper during the holidays, when shoppers lean hardest on reviews as the data suggested businesses flagged in November and December saw declines several times larger than at other times of year. The main takeaway for restaurant operators is that customer trust has measurable economic value, and losing it can have lasting consequences, Cao said. “Operators should therefore treat the credibility of their reviews as a long-term business asset. Attempts to inflate ratings can put customer trust and future demand at risk, with consequences that extend beyond the platform’s immediate penalty.” The study examined two types of Yelp alerts. The first involved documented evidence that someone offered compensation for reviews, such as cash, discounts, or free meals/products. The second involved suspicious review patterns suggesting coordinated manipulation, such as connections to review rings or unusually clustered activity from a single source. These are different grounds for an alert: one relies on direct evidence of compensation, while the other identifies patterns suggesting manipulation, Cao explained, noting that a review does not have to be entirely fabricated to violate Yelp’s policies; offering an incentive in exchange for a review is also prohibited. “Businesses should build their review practices around authentic customer experiences and the rules of each platform,” he recommended. “Where review requests are permitted, invite honest feedback without prescribing a rating or scripting what customers should say, and avoid selectively asking only satisfied customers.” Yelp specifically prohibits soliciting reviews, including requests without compensation, so operators need to follow its stricter policy, he added. Employees and outside marketing agencies should receive clear instructions about acceptable practices, and operators should check how reviews are obtained. “The broader lesson from our research is to protect the credibility of customer feedback as a lasting reputational asset,” Cao said. “Consistent service and constructive responses to feedback provide a sound foundation for that effort and especially for the long-horizon performances.” Operators must identify and stop practices that triggered the penalty, including auditing the work of employees and outside marketing or reputation-management agencies. Where manipulation occurred, Cao would recommend acknowledging what happened and explaining the concrete safeguards introduced to prevent it from happening again. Operators should also not assume recovery will follow automatically once a warning disappears being the relative decline in customer traffic persisted throughout the 18 months following the initial alert. “We did not test which recovery strategies work best, but the practical implication is to treat rebuilding trust as a sustained effort,” Cao suggested. “That means delivering consistent customer experiences, addressing complaints constructively, and tracking customer traffic and repeat business alongside online ratings.” The Federal Trade Commission’s review rule reinforces that review management is a compliance responsibility as well as a marketing function, Cao said. Businesses need to understand how reviews are obtained, whether incentives or business relationships require disclosure, and how negative feedback is handled. For example, incentives cannot be explicitly or implicitly conditioned on a review expressing a particular sentiment, whether positive or negative. “Disclosing payment does not make purchasing five-star reviews acceptable. The rule does not categorically prohibit incentives for reviews that are independent of sentiment, but disclosure requirements and other standards against deceptive practices still apply. Operators must also follow platform policies, which can be stricter: Yelp prohibits incentivized reviews altogether.” ## Entities - Operations (sector) - Federal Trade Commission (regulator) - Yelp (company) - Modern Restaurant Management (publication) - Barbara Castiglia (person) - online reviews (topic) - customer trust (topic) - George Mason University (company) - Yi Cao (person) - yelp flags (topic) - foot traffic loss (topic) --- Originally reported by Barbara Castiglia, Modern Restaurant Management (https://modernrestaurantmanagement.com/customer-trust-is-a-long-term-asset/).
