Reviews exist because other people's experience can be useful. They are also a target, because a stack of praise can move a listing toward the top of a search and toward a "buy" click. Official consumer bodies have been warning about this for years, which is a sign the problem is ordinary enough to plan for, not rare enough to ignore.
This guide gathers practical checks from the U.S. Federal Trade Commission, the UK Competition and Markets Authority and Which?. It does not claim you can spot every false review by eye.
This is educational information, not legal advice.
Why a star average is not enough
A single number feels precise. It hides who wrote the comments, whether they bought the item, whether they were paid or given a product, and whether anyone removed the quieter opinions.
The FTC's guide to buying from an online marketplace is direct: check the seller's ratings and read comments from recent buyers; check several sources; consider where a review is posted, who wrote it and the reviewer's history; and do not rely on star ratings alone, because some reviews and ratings are fake or misleading. Fake reviews, the FTC says, can be positive or negative. Some dishonest competitors place negative reviews. It is not always clear that a reviewer received something, such as a free product, in exchange for writing a review. Some sites label incentivised reviews, and some do not.
That paragraph is already a method. Stars start the conversation. They do not end it.
What UK guidance asks you to look at
The CMA's tips for shopping online add three habits that travel well:
- Look for verified purchases, which confirm that the person writing the review bought through the site (when the site offers that label).
- Check both positive and negative reviews.
- Make sure the reviews are about the actual product.
Those checks sound obvious until you are in a hurry. A burst of five-star comments that talk about shipping speed and not about the item, or that could apply to almost anything, are less useful than a specific description of how the thing worked after a week.
Which?, the UK consumer organisation, publishes its own guide to spotting fake reviews. Among other points, it suggests looking beyond a wall of five-star ratings, actually reading the comments, watching the dates (many reviews posted at once can be a warning), sorting by most recent rather than by a default "top reviews" order, taking extra care with brands you do not recognise, and looking for signs that someone was offered a gift card, a refund or another incentive. It also notes that negative comments can reveal patterns, and that reviews should be about the actual product.
We are summarising those official and specialist consumer pages, not replacing them. If a detail matters to you, read the original guides through the links below.
Patterns that deserve a slower look
No single clue proves a review is fake. A genuine buyer can be brief, delighted or annoyed. A combination of clues is a reason to widen the search rather than to appoint yourself a detective:
- A sudden pile of similar comments in a short window.
- Wording that repeats from card to card, or that could describe almost any product.
- Accounts that appear to exist only to praise one item.
- A perfect or near-perfect average that does not match more specific complaints you find elsewhere.
- Photos or videos that Which? notes can be requested by sellers who incentivise praise (common in some investigations, not proof on their own).
- A reviewer who admits they have not used the item yet.
The FTC also reminds shoppers that incentives are not always labelled. A glowing review from someone who received the product for free may still contain useful information, but it is not the same as an independent purchase.
Check more than one place
Both the FTC and Which? tell you not to rely on a single pile of comments. Search for the product or seller name plus words such as "review" or "complaint," and look at more than one site. If every independent source tells a similar story, you have more to go on than if one marketplace page is glowing and everywhere else is quiet or troubled.
When the seller is a person or small shop on a marketplace, read comments about the seller as well as about the item. The FTC suggests contacting the seller if you have questions, and choosing someone else if the answers are not satisfactory. A seller who cannot explain postage, returns or the condition of the item in writing is giving you information, even if the star average looks fine.
What software cannot settle for you
It is tempting to paste a page of reviews into a tool and ask whether they are fake. Wording alone is a weak test. Some false reviews are written to sound ordinary. Some genuine reviews are short or awkwardly phrased. Official guides focus on sources, dates, reviewer history, incentives and whether the comments match the product, not on a feeling that the prose is "too polished."
If you use a tool to group praise and complaints after you have gathered comments from more than one place, treat the result as a summary of what you fed it. It cannot see who was paid, who bought the item or which comments were removed.
Incentives, samples and labelled testimonials
Not every complimentary review is a secret advert, and not every advert is a crime. The FTC notes that it is not always clear a reviewer received something in exchange for writing, and that some websites label those reviews when they know about an incentive.
If a site marks a comment as sponsored, incentivised or as a sample, read it with that in mind. The person may still describe the product accurately. They were also handed a reason to write. A page that is almost entirely labelled incentives, or that never shows a middling opinion, is a thinner source than it first appears.
Which? suggests watching for people who mention gift cards, refunds or being asked to change a negative review. Those details sometimes surface in the less glowing comments, which is another reason to read them. Searching the review text for words such as "gift card" or "refund," where a site lets you search, can turn up warnings other buyers have already written.
How reviews fit with the rest of the purchase
How reviews fit with the rest of the purchase
Reviews are one input next to the listing, the photos, the returns policy, the payment method and the total price. A well-reviewed expensive item listed far below what other sellers ask may still be a listing to handle with care, as the FTC notes in its marketplace guidance. A poorly reviewed cheap item may simply be cheap.
If you cannot form a clear picture after reading recent comments in more than one place, it is acceptable not to buy. Waiting is a decision too.
A short reading routine
When a listing depends on its reviews, give yourself a few minutes:
- Ignore the average long enough to open the comments.
- Sort by most recent if you can.
- Read a mix of high, middle and low ratings.
- Ask whether the comments describe the product you would receive.
- Look at dates and at any verified-purchase labels.
- Repeat the search on at least one other site.
- Only then decide whether the stars still mean what they seemed to mean.
That routine will not catch every false review. It will make you harder to hurry, which is often the point of a manufactured average.
