Raise your score in Google Maps is not only a competitive advantage: it is a decisive factor in attracting customers, improving your local visibility and building immediate trust. However, the big question that most businesses ask themselves is always the same: how many reviews do I need to get a higher star rating? And how do I know how much further I need to go to improve my rating?
In this guide I explain in a clear, practical and non-technical way how the calculation works, what factors influence it and how you can speed up the process with the help of automation and artificial intelligence.
Why is it difficult to rank stars on Google Maps?
Google Maps does not calculate your rating by simply doing a basic average. Their system takes into account:
- The total number of reviews
- The cumulative average
- The quality of new valuations
- The additional weight of recent reviews
- Business behaviour and interaction (responses, speed, consistency)
So even if you receive several positive reviews, your average may take a while to move, especially if you have a lot of accumulated reviews.
The basic calculation: how to find out how many reviews you need to raise your average
In order to know how far you still have to go before you reach the star level, it is useful to have a rough estimate. Although Google does not publish its actual formula, there is a very reliable approximation used in online reputation.
Simple explanation (integrated and clear)
You don't need to understand the formula to understand how it works. You just need to be clear about these three principles:
- The more reviews you have, the harder it is to move your average.
- The higher the rating you are looking for, the more positive reviews you will need.
- New reviews must be better than your current average (ideally 5 stars) for you to really move up.
Thus, a business with 150 or 200 reviews may need dozens of 5-star ratings to go up by only 0.1 points, while one with few reviews will see much faster changes.
And that is also why 4-star reviews help very little when you already have a high average: they are positive, but not enough to push the rating up.
Practical method without formulas (quick and useful)
If you want to know how much you are missing without doing any calculations, just follow these steps:
1. Look at your average and current number of reviews.
From your Google Maps listing → Reviews → “Summary”.
2. Define your objective
Up from 4.2 to 4.3, or from 3.8 to 4.0, for example.
3. Use an estimation tool
Platforms such as wiReply allow you to see:
- Your projected average
- How many reviews do you need to upload
- The trend of your ratings
- If a new review will move your score
- What impact do recent reviews have
This avoids manual calculations and gives you real-time information.
Factors influencing what you need to raise your star rating
1. Your total volume of reviews
The most important factor. The more volume, the more effort.
2. The quality of your latest reviews
Google gives more weight to the most recent ones.
3. Competition
Your file competes with similar businesses. Moving up from 4.2 to 4.4 can give you a huge jump in local visibility.
4. The speed of reception
A steady stream of positive reviews indicates a stable service, which indirectly influences the algorithm's perception.
How to speed up the process of raising your rating
Rising in the number of stars depends not only on the number of reviews, but also on how you generate and manage them.
1. Ask for reviews at the right time.
Right after a good experience, when the customer is satisfied.
2. Facilitates direct linking
It avoids the customer having to search for your file:
a QR, an SMS, an email or a direct button multiplies the number of reviews received.
3. Automate applications with AI
Companies that automate the request for reviews get 3 to 5 times more ratings.
With wiReply, for example, you can:
- Send automatic requests by SMS or email
- Schedule smart reminders
- Personalise messages according to customer type
- Filter out dissatisfied customers to avoid negative reviews
- Measure how many reviews you are short of a rating increase
4. Always respond to all reviews
The algorithm values the interaction and consistency of the business.
5. Manage dissatisfied customers before they value
Many businesses lower their average not because of a lack of positive reviews, but because they receive a negative review at the wrong time.
Automation allows:
- Detecting dissatisfied customers
- Redirect them to a private channel
- Solve the problem before they publish
Conclusion: you can find out how far you have to go to reach the next star level... and achieve it faster.
