All scores in Google+ Local are determined by user reviews.
Individual user ratings map to a 0 to 3 point scale.
|Poor to Fair||0|
We take these ratings, average them, and then multiply by ten to arrive at averaged scores. We then may adjust the overall ratings based on user inputs and other signals to ensure these ratings best reflect the quality of the establishment.
|26-30||Extraordinary to perfection|
|21-25||Very good to excellent|
|16-20||Good to very good|
|11-15||Fair to good|
|0-10||Poor to fair|
When you’re searching for locations in Google+ Local, you may see these scores depicted in two ways:
Scores with multiple aspects
These scores will show you several scores for different aspects of the business. For example, restaurants are scored across three areas--food, decor, and service--with food being the primary aspect.
When we don’t have enough user ratings on different aspects, we will just show an overall score. An overall score is comparable to a score in the primary aspect for a location, like food for restaurants.
