How Does Yelp's Rating Actually Work?

The software specifically watches for reviews that look prompted or encouraged by the business, reviews from users Yelp doesn’t have enough history on yet, and reviews from accounts with an undisclosed conflict of interest — competitors, employees, friends, or family. Per Yelp’s own documentation, no Yelp employee can manually override what the software decides, and a review’s status can change over time as Yelp learns more about the reviewer.

That combination — an opaque, automated filter, and a policy that actively penalizes anything that looks solicited — is why we don’t show a rating calculator for Yelp. A tool that implied “collect N more reviews to reach X stars” would be modeling inputs that may never reach the visible number, and a real share of them won’t. What we do provide below is grounded in what Yelp actually publishes about how the rating behaves and what a business can do within its rules.

• Recommendation software, not a raw average — a review only counts toward the star rating and review count if Yelp’s automated system marks it “Recommended”; Yelp’s own support center puts the platform-wide recommended share at roughly three-quarters of submissions.
• Conflicts of interest — reviews suspected to come from competitors, current or former employees, or friends/family of the owner are filtered out of the count.
• Apparent solicitation — reviews the software believes were prompted or encouraged by the business are down-weighted, independent of whether anything was offered in exchange.
• Reviewer reliability — reviews from newer or less-active Yelp users may not be recommended until Yelp has more signal about that reviewer’s activity.
• Content Guideline violations — reviews that are off-topic, harassing, or otherwise break Yelp’s guidelines can be removed entirely through Yelp’s flagging process, separate from the recommendation filter.
