Why Google Reviews Matter

Google reviews are one of the most influential factors affecting your business's online reputation, search engine ranking, and customer trust. Reviews impact consumer decisions, and maintaining a high rating is crucial for business growth.

Understanding Google Reviews and Ratings

Google displays reviews in the form of an overall rating, which ranges from 1 to 5 stars, alongside individual customer reviews. This rating is determined by an average calculation based on the distribution of all received reviews. The more 5-star reviews a business receives, the higher its overall rating. Conversely, lower-rated reviews can significantly impact the rating.

How Google Calculates Ratings

Google's rating system follows a weighted average approach. The formula to determine the average rating is:

Google Rating Formula

Where:

  • N1 = Number of 1-star reviews
  • N2 = Number of 2-star reviews
  • N3 = Number of 3-star reviews
  • N4 = Number of 4-star reviews
  • N5 = Number of 5-star reviews

Google rounds the rating to one decimal place, meaning that even a slight increase in the number of 5-star reviews can improve a business's overall rating.
