Understanding Google’s Star Rating System

Google’s star rating system is a cumulative average, meaning that it calculates an overall rating based on all the individual ratings a business has received. The system operates on a 1 to 5 scale, with 5 being the highest possible score. Each review contributes to the average, which is then displayed as the business’s overall star rating on Google.

The critical aspect to understand is that the star rating is not based on a fixed number of reviews but on the average of all ratings. Therefore, there is no one-size-fits-all answer to how many reviews it takes to increase a star rating by one. The number of additional positive reviews required to elevate a star level depends on both the current average rating and the total number of reviews.

The Math Behind Improving Your Star Rating

To conceptualize how reviews impact the star rating, consider the formula for calculating an average: the sum of all rated points divided by the total number of reviews. If a business wishes to improve its star rating, it must acquire new reviews that are higher than its current average.

For instance, if a business has a 4.0 rating from 100 reviews, the sum of rated points is 400. To increase the average to a 4.1, the business would need to add reviews with an average exceeding 4.0. If a business receives five new 5-star reviews, the new average would be calculated as (400 + 25) / (100 + 5) = 4.04, nudging the rating upwards.

This illustrates that the impact of each additional review diminishes as the total number of reviews grows, making it increasingly challenging for established businesses to alter their star rating significantly with just a handful of new reviews.

Strategies for Improving Your Google Star Rating

Encourage Customer Reviews

Actively asking satisfied customers to leave a review can significantly increase the number and quality of reviews received. Businesses can leverage post-purchase emails, QR codes at physical locations, or verbal reminders to encourage this feedback.

Respond to Reviews

Engaging with both positive and negative reviews demonstrates to customers that the business values their feedback. Addressing concerns raised in negative reviews can also mitigate their impact and sometimes even lead to customers updating their review to a more positive one.

Monitor and Analyze Your Reviews

Regularly checking your reviews can provide valuable insights into customer sentiment, allowing for improvements in areas that may be lacking. Additionally, understanding the patterns in your reviews can help tailor strategies to enhance customer satisfaction and, consequently, your star rating.

Focus on Service Quality

Ultimately, the most effective strategy for improving your Google star rating is to offer excellent service or products. Satisfied customers are more likely to leave positive reviews, naturally elevating your average rating over time.


The journey to improving a Google star rating is ongoing and requires a strategic approach to customer feedback and service quality. There is no magic number of reviews that guarantees a star level increase, as this is contingent upon the existing average and review count. By fostering an environment that encourages positive reviews, actively engaging with customer feedback, and continuously striving for excellence, businesses can effectively influence their Google star ratings, enhancing their online reputation and attracting more customers.
