How many reviews to reach your target rating?

It uses your current review count, current average rating and target rating to compute how many new reviews of a given star rating you need. The formula is: required reviews = (current reviews × target rating − current reviews × current rating) ÷ (new review rating − target rating).

Google averages all of your reviews. Once you have many reviews, a single new one barely moves the needle. The higher your existing review count, the more new reviews you need to shift the average.

You generally cannot delete legitimate negative reviews on Google. You can flag spam or policy-violating reviews, but the most reliable path to a higher rating is collecting more positive reviews over time.

4.5 stars is the unofficial benchmark consumers look for. Below 4.0 customers start to hesitate; above 4.7 you stand out from competitors in most local categories.

Ask happy customers right after a great experience, share a short Google review link in WhatsApp follow-ups, and respond to every review you receive — Google rewards active profiles.
