How Much Revenue Do Bad Reviews Cost a Restaurant?

A widely cited Harvard Business School study found that a one-star increase in a restaurant’s Yelp rating was associated with a 5–9% increase in revenue.

Why one star matters so much

Diners compare ratings side by side. Small differences change which restaurant gets picked, especially for people who have never visited.

How unfair reviews add up

A few fake or policy-violating one-star reviews can lower your average enough to push you below competitors, even if most customers are happy.

Estimating your own loss

Take your annual revenue, estimate how much your rating would rise without the unfair reviews, and apply the research range. It is a rough estimate, not a guarantee, but it shows the scale.
