How to spot a fake review: nine signals that actually work
Most advice about spotting fake reviews is folklore. Here are the signals that hold up, the ones that do not, and why the pattern matters more than any single review.
Most guidance on spotting fake reviews is folklore passed between blog posts. "Watch for perfect English." "Be suspicious of five stars." Neither survives contact with real data: plenty of genuine customers write immaculately, and most people who bother to write at all are either delighted or furious.
What follows is what actually separates a manufactured review from a real one. None of it is conclusive on its own. Fraud is a pattern, not a single review — which is the most important thing on this page.
1. It describes the product, not the transaction
A real customer remembers friction. The delivery that came a day late, the person on the phone, the size that ran small, the invoice that needed chasing. A paid reviewer has only the marketing page to work from, so they write about features.
If a review could have been written by someone who never bought the thing, it probably was.
2. There is no specific detail that could be wrong
Genuine reviews contain checkable specifics: a date, a branch, a model number, a name. Fabricated ones stay vague, because every specific is a chance to be caught out.
"Great service, highly recommend" is not evidence. "Booked the 8am slot at the Halifax branch, they had the part in stock" is.
3. The timing clusters
One business receiving four reviews in a decade, then eleven in a fortnight, has not suddenly become popular. It has either bought reviews or run a campaign. The two look identical on most platforms, which is why arrival dates should be visible.
Look for a graph, not a number. If a platform will not show you when reviews arrived, ask why.
4. The reviewer has no history — or too much of it
A single-review account is not proof of anything; everyone starts somewhere. But a single-review account that appeared the same week as forty other single-review accounts praising the same business is a farm.
The other tell is the opposite: an account reviewing a plumber in Aberdeen, a hotel in Cornwall and a dentist in Leeds within three days.
5. The negatives are decorative
Sophisticated fakes include a mild complaint to seem balanced. You can spot the difference: a real complaint costs the business something. A decorative one does not.
"Wish it came in more colours" is decorative. "They billed me twice and took three weeks to refund it" is not.
6. The language is oddly consistent across reviewers
Different people write differently. When six reviews share sentence rhythm, the same slightly-off idiom, or the same unusual phrase, they came from one hand or one template.
7. It answers a question nobody asked
Reviews that name the company in full, repeatedly, and mention the town, read like search-engine bait because they are. Real people write "they" and "the shop".
8. The rating and the text disagree
A three-star review describing an excellent experience, or a five-star review listing three serious problems, usually means the text was written by one person and the rating chosen by another.
9. It arrived from nowhere
Where a review comes from matters. A review left after a confirmed purchase carries more weight than one left by an anonymous visitor who found the page. Not because anonymous reviewers lie, but because a verified one is much harder to manufacture at scale.
Three tests that do not work
Perfect grammar. Plenty of real reviews are well written. Plenty of fakes are deliberately sloppy to seem authentic.
All five stars. Most satisfied customers who write anything give full marks. A distribution weighted to five stars is normal, not suspicious. What is suspicious is the absence of anything else.
Reviewer photos. Trivially generated, and the absence of one means nothing.
What to look at instead
Stop assessing individual reviews and look at the shape of the whole:
- When did they arrive? Steady over years, or in bursts?
- What proportion are verified, and verified how?
- Does the business reply to criticism, or only to praise?
- Has anything been removed, and does the platform say so?
A business with a 4.2 built from three years of verified, mostly-answered reviews is telling you far more than one with a 4.9 from ninety reviews that all arrived in March.
We publish all four of those things on every profile, including the ones that make a business look bad, because a rating you cannot inspect is just a number someone else chose.
