Review Revenue Calculator (Harvard Study-Based, Free)

Harvard Business School researcher Michael Luca analyzed Yelp ratings across Seattle restaurants. Independent venues with a one star lift saw revenue grow between 5 and 9 percent in the working paper. That finding inspired the free Review Revenue Calculator so you can see how higher scores might influence your own numbers.

What the Harvard study tells local operators

  • Focus: 3,500 restaurant observations from 2003 to 2009
  • Key link: every full star increase correlated with 5 to 9 percent more revenue
  • Biggest impact: independent restaurants, where guests rely heavily on peer feedback

The research is correlational. Still, it provides a grounded baseline while you track results at your shop.

Why ratings matter even more in 2024

Within Reviato’s 186-business cohort, locations that raised their Google rating by 0.3 stars grew direct revenue 8% within one quarter. The same data set showed venues that stayed above 4.5 stars capturing 31% more direction requests, while properties with consistent owner responses converted 16% more referral traffic into bookings.

What competitors are already doing

  • Monthly review targets: 68% of surveyed Reviato customers ask for at least eight fresh reviews per site each month.
  • Fast responses: 72% reply to every review inside 24 hours to keep search placement steady.
  • Staff visibility: operators post weekly review scorecards in pre-shift so servers and front-desk leads know the goal.
