Star Rating
Definition
A star rating is the numerical score assigned to a business by a customer review, typically on a 1-to-5 scale, and the average of these ratings — usually displayed to one decimal place — is among the most influential signals affecting purchase decisions for local businesses.
Across BrightLocal's annual Local Consumer Review Survey, customers consistently report that they read more reviews and click through to businesses with higher star ratings. The threshold for serious consideration is around 4.0 stars; below 3.5 most customers exclude the business from consideration entirely.
The optimal display range — the "sweet spot" for ratings — sits between 4.4 and 4.7 stars. Below 4.4 the rating signals problems; above 4.7 it can read as suspicious or curated (the platform showed only positive reviews). Businesses that perform too perfectly raise quality-rater attention.
Star ratings are calculated differently across platforms. Google uses a simple arithmetic mean of all displayed reviews, weighted by recency to a small degree. Yelp uses an undisclosed algorithm that can suppress some reviews into the "non-recommended" pool, affecting the displayed average. TripAdvisor uses a quality-and-recency-weighted average that can lag the simple mean by months.
The path to improving a star rating is rarely "respond to negatives only" — it's responding to enough negatives that they get amended or removed, plus generating enough new positives to dilute the historical average.
