How to improve your Google rating: the arithmetic, the asking, and what Google allows

What it takes to move a star average, the request method that stays inside Google policy, and the operational fixes that change the reviews you get.

Published by AI Knows Us · Updated 12 October 2026

To improve your Google rating you need three things working at once: fix whatever is producing the low ratings, ask every customer for a review as part of the normal job rather than as a campaign, and reply to all of them. The reason the third one matters is arithmetic. An average only moves when enough new high ratings arrive to outweigh the old ones, and the number required is calculable, so you can set a target that is a plan instead of a hope. Google permits you to ask for reviews and prohibits offering anything in exchange for them, which shapes how the asking is designed.

The arithmetic, so you know what you are aiming at

To work out how many new five star reviews it takes to reach a target average, use this:

new five star reviews needed = n x (target - current) / (5 - target)

n       = your current number of reviews
current = your current average
target  = the average you want

Current reviews	Current average	Target	Five star reviews needed
20	3.8	4.5	28
80	4.2	4.5	48
200	4.3	4.6	150
40	4.6	4.8	40

Three things fall out of that table. A small review count moves quickly, which is the best time to start. A large review count is slow to move, so protecting a good average is worth more than repairing a poor one. And the closer your target is to five, the steeper the requirement becomes, which is why 4.6 is a better goal than 4.9 for most businesses.

Divide the number you need by your monthly customer count and your realistic completion rate. If you serve 120 customers a month and one in five leaves a review when asked properly, you gain roughly 24 reviews a month, so a 48 review target is a two month plan with a number attached.

What Google allows

Google's own guidance in Tips to get more reviews is short and clear on the two points that matter.

Asking is allowed. Google tells businesses they can share a review link or a QR code with customers. Your profile generates that link for you.
Incentives are prohibited. Offering free or discounted goods or services in exchange for a review, for changing a review, or for removing a negative one is treated as fake and misleading content and is strictly prohibited.
Replies are not a promotional channel. Google advises against using replies to offer deals, and in favour of replies that acknowledge the experience.

Two more warnings worth having in mind, because they are commonly sold as services. Buying reviews is a direct breach of that policy and the reviews are removable. Asking only the customers you expect to be happy, sometimes called gating, defeats the point and produces an average that does not survive the first honest review.

The request that actually gets completed

Ask at the moment of relief. Not at the invoice, at the point where the customer has the result in their hands. For a service business that is the end of the visit. For a product it is a few days after delivery.
One link, no detours. Use the short review link from your Business Profile so the form opens directly. Every extra step halves completion.
Ask by the channel you already use. If you message customers, message. A QR code on the counter, the invoice and the van works for walk in trade.
Give staff one sentence. "If today went well, a Google review genuinely helps us. Here is the code." Written on a card, with the code on it.
Ask everyone. Routine beats selection. A steady flow including the occasional four star review reads as real, and recency counts for a lot in how a profile is judged.
Make it somebody's job. One person owns the weekly number. Programmes without an owner last three weeks.

Fix the cause before you chase the average

Read every one and two star review from the last year and sort the complaints into themes. In most businesses three themes cover almost everything: waiting, communication and expectation. Each one has an operational fix that costs less than a marketing campaign.

Waiting. Publish realistic timings and tell people when they change. A delay the customer was warned about rarely becomes a one star review.
Communication. One named contact and one promised update time removes most of the frustration in a complaint.
Expectation. If the same misunderstanding appears three times, your quote, your menu or your product page is the thing to fix.

Then close the loop: when you have fixed a theme, say so in your reply to the reviews that raised it. That reply is read by everyone who comes afterwards.

Replying, properly

Reply to every review, including the five star ones, with something specific rather than a template.
For a negative review: thank them, acknowledge the specific issue, say what you have changed, and move the detail offline with a named contact. Three sentences.
Reply once. A second public reply to an unhappy customer turns a review into a thread, and the thread is what people read.
Keep offers out of replies, both because Google advises against it and because it makes an honest apology look like a transaction.

Our page on how to reply to Google reviews has worked examples for each kind.

When a review breaks policy

Some reviews qualify for removal: content that is off topic, abusive, clearly from somebody who was never a customer, or posted by a competitor. These are flagged through the profile and judged against Google's content policy rather than against your preference. What qualifies, how to report it and what to do while you wait is set out in our page on removing a negative Google review.

A ninety day routine

Week one. Claim or confirm the profile, complete every field, and generate the review link and QR code. Our note on adding or claiming a Business Profile is Google's own instruction for this step.
Week two. Read the last year of low ratings, pick the top theme, make the operational fix.
Weeks three to twelve. Ask every customer, reply within two working days, and record the count and average every Monday.
Month three. Recalculate using the formula above, compare against plan, and adjust the ask rather than the target.

What gets asked about improve your Google rating

How long does it take to raise a Google rating?

It depends on your current count and your customer volume rather than on time. Work it out with the formula: the number of reviews needed divided by the number you can realistically collect each month gives you the answer in months.

Can I ask customers to remove a bad review?

You can ask politely once, usually after resolving the problem, and many customers will update a review themselves. What you cannot do is offer anything in exchange, which Google treats as prohibited content.

Do replies affect my rating?

Replies do not change the arithmetic. They change what the next reader concludes, which is the thing that actually decides whether they call you, and they encourage more reviews because customers see that reviews are read.

Is it bad to have only five star reviews?

A perfect record with few reviews reads as thin. A strong average with a few four star reviews and good replies reads as a real business, and it is also what a steady routine naturally produces.

What about reviews on other platforms?

Build the Google routine first because it feeds the map pack, then extend the same request to the one or two platforms your industry actually uses. Our page on why listings and reviews move AI answers explains where else they are read.

Where to go from here

Where your rating is quoted back to a customer

A 4.6 from 212 reviews is read first on Google. It is also quoted. When someone asks an assistant for a well reviewed dentist or garage nearby, the reply often repeats ratings and picks phrases from the reviews themselves.

That gives the asking routine in this article a second reader. The words customers write about your staff and your speed are the words an assistant is likely to repeat to the next person. Ask for a recommendation in your category and area, and read what is said about you and your neighbours. AI Knows Us captures those answers for repeat comparison.
