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:
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.
