Online reviews and reputation, by the numbers

By ReputationKiln Editorial · Published · Updated

There is no single agreed number for most of this, and anyone who quotes one dramatic statistic without a source is doing the very thing this site warns about. Estimates vary by platform, sector, method and year. What follows is the best-sourced figure for each theme, with where it comes from and when we checked it, leaning on primary sources, the regulators, the platforms' own transparency reports, and peer-reviewed work, over the secondary write-ups. We name our numbers so you can check them, which is rather the point of the place.

How common are fake reviews

A 2023 United Kingdom government study estimated that roughly eleven to fifteen per cent of reviews were fake across several common categories, with a separate impact assessment putting prevalence higher, up to a quarter to a third, across eight large platforms. A 2024 analysis of seventy-three million reviews in the home, legal and medical sectors found about fourteen per cent extremely suspicious. The honest summary: prevalence clusters somewhere around the low-to-mid teens on mainstream platforms, higher in some sectors, with no universal figure.

What reviews are worth

Studies across millions of reviews found that a page with as few as five reviews can be far more likely to convert than one with none, and that purchase likelihood peaks at an average rating of roughly four-point-two to four-point-seven, then falls toward a perfect five. On the survey side, the large majority of consumers read reviews before choosing a local business, a meaningful share will not use one with too few, and a strong majority deliberately seek out the negative ones to check the picture is real.

What the platforms remove

The big platforms now report removing fakes at industrial scale, hundreds of millions a year between them, much of it caught automatically before anyone sees it, and the numbers are rising year on year. Treat the exact figures as dated and ephemeral, but the direction, more removed each year, is consistent.

What it can cost a business

Penalties for fake-review practices, current as of mid-2026 and revised periodically: the United Kingdom, up to the greater of three hundred thousand pounds or ten per cent of global turnover; the United States, up to around fifty-three thousand dollars per violation; Australia, up to the greater of a hundred million dollars, three times the benefit, or thirty per cent of turnover; with strong penalties also in South Africa, India and Canada. The cases brought have landed those penalties on the business that bought or hid reviews, not on a faceless seller.

The honest health warning

Every figure here carries a date because it will move, and a few widely-circulated numbers, the very large global "cost of fake reviews" totals, are heavily estimated secondary figures rather than hard facts, so we have left them out or flagged them. If you see one quoted with confidence and no source, treat it the way you would treat any claim that cannot be checked.
