Get StartedFrequently Asked Questions
How does Google calculate star ratings?
Google calculates your rating as a weighted average of all reviews. One new 5-star review has less impact when you have 500 reviews than when you have 10. This calculator uses the exact same formula.
Why is 4.5 stars the magic number?
Studies show businesses with 4.5+ stars convert 3× better than those below 4.0. Google's local search algorithm also favors businesses with higher ratings and more reviews in the local pack.
Can 1-star reviews permanently damage my rating?
One 1-star review can significantly drop your average if you have few total reviews. Use this calculator in reverse — change "new reviews will be 1-star" to see the damage, then calculate how many 5-stars offset it.
How do I get more 5-star reviews quickly?
Send a review request via WhatsApp immediately after a successful transaction. Our research shows 68% of customers who receive a WhatsApp review request complete it within 10 minutes. Reputoo automates this.
Does Google remove fake reviews?
Yes. Google actively detects and removes fake reviews. Never buy fake reviews — accounts get banned. The most effective approach is automated review collection from real customers via WhatsApp.
What if I have too many bad reviews to recover from?
With enough new 5-star reviews, any rating is recoverable. The calculator shows exactly how many real reviews you need. Automated collection via WhatsApp is the fastest legitimate method.
