How many reviews you need, and what rating actually converts

Twenty is the floor: 47% of consumers say they will not use a business with fewer than that. Four stars is the other floor — 68% will only use a business rated four or above, and 31% now require 4.5 or more, up from 17% the year before (BrightLocal, 2026).

After that it is recency rather than volume. 74% say they only care about reviews written in the last three months.

A flawless rating reads as filtered. Research into purchase intent repeatedly finds a peak somewhere between 4.5 and 4.8, above which buyers become suspicious rather than reassured — they start looking for the catch instead of the buy button.

A handful of critical reviews with good replies does more for credibility than removing them would. It is the clearest case where the honest option is also the commercial one.

Count establishes that you are real; twenty reviews clears the threshold for most people. Recency establishes that you are still good, and three-quarters of consumers discount anything older than three months. Past a few dozen reviews, recency does far more work than volume.

Consumer expectations moved fast between 2025 and 2026 — the share requiring 4.5 stars nearly doubled. A rating that was fine last year may not be this year.

Treating the target as a number to reach rather than a rate to sustain. A business that collected 200 reviews in 2023 and none since looks worse than one with 60 that arrived steadily, because the second one is visibly still operating.

The other mistake is comparing against a national average rather than the three competitors in the same search result, which is the only comparison a customer actually makes.

Twenty reviews minimum, four stars minimum, newest review under three months old, and after that match or beat whoever you appear alongside. That is achievable with two or three reviews a month for most small businesses.
