Local businesses get updated rating system Jade W. 5/15/13 11:47 AM

Today, with the launch of the new Google Maps, we announced a change to the way people rate businesses on Google on the Google and Your Business blog.


Users who opt-in to the new Google Maps will rate businesses on a scale that ranges from one to five stars.  The system maintains the precision of the former 30 point scale while improving the readability and accessibility of the business listings.


As a business owner, you’ll notice that past ratings have been translated to the five star system. Previously, users rated businesses from “Poor-Fair” to “Excellent” on several dimensions; these ratings were converted to numerical scores and expressed on a 30 point scale.


We’re mapping individual ratings to the star system using the following framework:


Previous rating scale

Five star system

Poor-Fair

2

Good

3

Very Good

4

Excellent

5


Your business’s overall rating is calculated from both old and new customer reviews as a 1.0 to 5.0 star rating. Old dimension ratings like “service” and “decor” will contribute to the overall rating. The new algorithm takes into account statistical uncertainty in the straight average of user scores to make the scores more reliable for places with only a few ratings.


Zagat reviews are still available throughout Google, and you’ll continue to see Zagat throughout Google products with editorial reviews and curated lists awarded to notable places


The changes will appear to some users today and will continue to roll out on Google Maps for Mobile, Google search results and Google+ Local in upcoming months.
