Crossing a Yelp display-rating threshold implies about 5%–9% higher revenue for independent Seattle restaurants; chain-affiliated restaurants show no rating response.
What this does not establish
A local historical restaurant RD does not establish effects for Google ratings, nonrestaurant SMBs, current algorithms, profit, footfall, or the value of buying or soliciting reviews.
Counterevidence & uncertainty
The causal-looking threshold response is concentrated in independents; chain affiliation nullifies the average rating effect, so a universal one-star revenue multiplier is contradicted by the same study.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral or commercial outcomes.
