An Additional Star on Yelp Can Boost Restaurant Revenues 5% to 9%

Reviews at the popular crowd-sourcing site Yelp.com are having a significant effect on the restaurant business, according to a study of more than 3,500 Seattle restaurants from 2003 through October 2009. But there is an interesting caveat: the effect does not seem to be seen for chains that already have spent considerable effort to create a well-defined "brand."

In other words, Yelp doesn't work for chain restaurants that already have spent heavily on branding. Chain restaurants in that category seem to be unaffected by changes in their Yelp ratings. If you were wondering whether content marketing can be an alternative to advertising, there is your answer.


Using data provided by the Seattle Department of Revenue, the study by Harvard Business School Professor Michael Luca found that a one-star increase in Yelp's five-star rating scale was associated with a quarter-to-quarter revenue rise of five percent to nine percent.

Luca combined Yelp reviews with revenues for every restaurant that operated in Seattle, Wash. at any point between 2003 and 2009. This suggests that consumer reviews present a new way of learning in the Internet age, and are fast becoming a substitute for traditional forms of reputation. Reviews affect revenue


Online consumer review websites provide more information to consumers than was previously thought to be cost effective, in large part because Yelp relies on user-generated content.


Consumer reviews also provide a substitute for more traditional forms of marketing, the study suggests. The study also suggests that other forms of reputation management, such as chain affiliation, may become less influential as websites like Yelp continue to gain traction. That means the value of a franchise might be less than it once was, for example.


Consumers rely on simple metrics such as the average rating and the number of reviews, and are more trusting of reviews that are written by "elite" reviewers. Yelp changes restaurant revenue
