The website will incorporate grades received from local health inspectors into its restaurant reviews, the Associated Press notes.
Restaurants in San Francisco will see their health inspection results appear in Yelp reviews first, followed by those in New York City.
Yelp has been collaborating with municipal health officials to include the grades in its reviews. New York grades restaurants using letter grades, with A representing the best results, while San Francisco uses a numerical scale up to 100, with higher numbers representing a superior grade.
Shares of Yelp rose almost 1% in Friday morning trading.
