How to Tell If a Product Review Was Written by a Bot
Generated reviews have a rhythm: no dates, no faults, no photos. The six-signal check that takes under a minute.
Short answer: Look for three things a real reviewer almost always includes and a generated one usually skips: a date or duration of use, a specific fault, and a photo. A five-star review with none of the three, posted in a cluster with others the same week, is not worth weighting.
Review sections have changed quickly. The obvious broken-English fakes are gone; what replaced them reads fluently and says almost nothing. That makes the old advice — look for bad grammar — useless, and a different check necessary.
Six signals, ranked by reliability
| Signal | What to look for | Weight |
|---|---|---|
| No duration | Never says how long they used it | High |
| No downside | Not one criticism across five paragraphs | High |
| Date clustering | Dozens of reviews within a few days | High |
| Generic nouns | "the product", "this item" instead of the name | Medium |
| No photos | Zero user images on a physical product | Medium |
| Reviewer history | One review only, or all five stars | Medium |
The one-minute routine
- Sort by most recent, not most helpful — helpful rankings are easy to game.
- Read three one-star and three three-star reviews first; genuine faults repeat.
- Ignore anything with no duration of use mentioned.
- Check whether the complaints in the low reviews are about the product or about delivery. Delivery complaints say nothing about quality.
- Search the exact product name plus "problem" outside the store.
Three-star reviews are the most useful category on any store because they mention both sides. If the purchase is a phone or laptop, pair this with what to consider before buying a new smartphone, which lists the specs that actually age. When a deal looks unusually good, the pressure tactics described in how to spot fake news online show up in shopping too.

Frequently asked questions
- Are verified purchase badges reliable?
- Partly. They confirm a purchase happened, not that the reviewer was unpaid. Use them as one signal, not proof.
- Do review-checking sites work?
- They catch obvious patterns and miss subtle ones. Treat their grade as a hint, then read the three-star reviews yourself.
- Is a small number of reviews a bad sign?
- Not necessarily. A new listing from an established brand is normal; a new listing with 500 reviews in a week is not.
