Competitor review gap calculator
They are 4.6 with 120 reviews; you are 4.2 with 37. How far is it, really?
How the number is worked out
To pass a competitor's rating you need n × (t − c) ÷ (5 − t) five-star reviews, where c is your current average, n your current count, and t their rating plus a hair. The count gap is a straight subtraction.
Read the two numbers separately: the rating gap is usually tiny and the count gap is usually huge. 4.5 against 4.6 is one tenth; 42 reviews against 380 is nine times — and the second is what a customer notices first.
Don't chase the rating first
Businesses on the same street nearly all sit between 4.3 and 4.7. Nobody picks a place because it has 4.6 instead of 4.5, but plenty of people trust 380 reviews over 42. So while the count gap is a multiple, spending your effort on the rating is the wrong direction.
One thing matters more than either number: whether the competitor's primary category is the same as yours. If it is not, you are not even in the same pool and no number of reviews will fix it. Paste both links into Compare with competitors to see that column, and profile completeness alongside it.
Closing the gap
Once you know how many, spread it over months with the Review goal calculator, and sanity-check the target against your trade with the Review pace estimator before you commit to it.

Where those reviews come from
The gap is now a number. That leaves one question: where those reviews come from — and they have to come without breaking any rules.
In practice, ten happy customers, and often not one of them writes a review — not because they do not want to, but because it is a hassle, and typing it out is worse. Review Helper cuts that step to thirty seconds: the customer scans your code, ticks a few things they actually experienced, and the page turns it into a sentence in their own words. Copy, paste, posted. We do not ghost-write and we do not post for anyone — what they write, and whether to post it, stays their call. Three free reviews for every Google listing, nothing to pay up front, no card needed. No monthly fee: you pay per use.
