How to Verify Authentic Customer Reviews? A Buyer’s Guide

At least 82% of people in the U.S. read online customer reviews before making a purchase. Online reviews are basically words by people about a service or product they’ve already used. People who are looking forward to trying the same service or product tend to trust these reviews like advice, which means reviews influence how people spend money.

That’s why, ideally, online customer reviews should be true so that buyers aren’t misguided, but that’s not always the case. In fact, many reviews posted online tend to be fake and misleading. And because of that, you can’t simply read and trust them; you need to verify their authenticity first.

This guide will teach you how to verify authentic customer reviews before buying something so you can make the decision more confidently.

1. Check the Reliability of the Source

The first thing to consider when reading reviews is the source platform. This is because the overall reliability of reviews varies greatly from source to source.

The Trust Search, for example, offers you verified reviews. The platform verifies individual reviews based on their transaction evidence through manual screening to prevent fake feedback. This means every review on our platform is checked by a human auditor before it goes live, making it much more trustworthy than unchecked reviews on platforms like social media.

Even though many online review platforms prevent fake reviews, they’re not entirely trustworthy.

Social media platforms in particular aren’t always reliable (except for their focused communities) because these platforms don’t have verified reviews. They don’t have strict reviewer guidelines or checks and balances in place to moderate reviews. This is to be expected on platforms that are multi-purposed and where customer reviews aren’t the main focus.

Anybody can make an account on social media, post a fake review, and make it appear like it’s true. Bot reviews are also very common on social media, which often appear in the form of fake comments praising a brand or a product. On the contrary, brands often remove genuine negative reviews on their posts, leaving only positive comments.

Another source you should be skeptical of is a company's official website. Many shady businesses don’t follow any business guidelines either. They shamelessly write and display fake reviews that praise them like no one does. These reviews are often AI-generated, have perfect and error-free writing, and are not taken from genuine review platforms.

Here are some sources that are generally more trustworthy than social media and official websites, ranked from most reliable to least reliable:

1. Evidence-Verified Platforms (e.g., The Trust Search)

2. Verified-Purchase Stores (e.g., Amazon "Verified")

3. Online Community Forums (e.g., Reddit)

4. Open Review Platforms like (e.g., Google Maps)

5. Social Media Platforms (e.g., Facebook)

2. Check Online Community Forums

Online community forums can be pretty helpful when you need to research about a product. Reviews in hobby-based or specific subreddits, for example, can be surprisingly honest and reliable, though not always.

A lot of reviews posted on these forums tend to be genuine and highly detailed. You can tell that just by reading the first paragraph of a critical review that this review seems genuine.

These spaces are generally reliable because they’re usually occupied by hobbyists and enthusiasts. And if anybody tries to post a fake review, in which they try to praise a poor product, that review will likely get downvoted, rebutted, proven wrong by commentors, and even possibly removed by moderators.

Here are some community forums you can check:

• Reddit

• Discord channels focused on specific interests

• Well-moderated community groups on Facebook

However, community forums aren’t free of fake reviews either. Some fake reviews are kept subtle and made to look genuine. Sometimes, you may find comments endorsing specific brands or products within reviews. Just remember, no matter the source, there’s no 100% fool-proof way of knowing if a review or comment is actually fake or real.

So while you read that one very deep and specific review on r/Earbuds, keeping a healthy amount of skepticism is still recommended.

3. Check the Review’s Date

Checking the reviews’ dates can help determine whether they’re possibly fake or real.

Bot reviews tend to be posted within a short duration, as well as other self-posted fake reviews. So if you’re reading reviews and most of them have the same date, they’re likely not real. This is much more likely to be true if the reviews are all:

• five stars,

• highly positive,

• short,

• perfect grammar, and

• posted by profiles with suspiciously common or made-up names (e.g., John Carlos)

It becomes even more suspicious if the product is newly launched. Sometimes, reviews posted within short durations are negative instead, which may be posted by competitor brands to hurt other brands’ ratings. These reviews might appear surprisingly negative and lacking reasonable statements.

In contrast, reviews that are posted on different dates, often with varying sentiments, tend to be more trustworthy.

So if you run a business and have received multiple negative reviews in a short duration that seem suspicious, don’t sit back and spend too much time investigating their authenticity. Instead, report them to the platform first. In the meanwhile, you should also consider responding to fake reviews by leaving a professional reply. Not only does replying to negative fake reviews help control the damage, but you also better connect with customers who might come across that review.

4. Examine the Review’s Language

Sometimes, when other patterns match, you can tell if a review is fake based on its language. We’re not just talking about grammatical language but the things people highlight and mention.

This is not a rule, but often, human-written reviews have imperfect grammar and a more natural way of expression. Human-written reviews don’t necessarily have spelling errors, but subtle errors like comma splices and common mistakes are, well, common.

By contrast, fake and AI-generated reviews tend to have perfect grammar. AI ones specifically may use em dashes (—) and semicolons (;).

But again, using em dashes and semicolons does not necessarily make a review fake. You’re supposed to watch out for multiple signs (i.e., language, date, star rating, source, etc.), consider if other signs are also present, and weigh the reviews’ authenticity yourself.

Another thing to watch out for is the reviews’ point of view and what they’re highlighting.

A real review might highlight something specific, point out a flaw, or give a mixed response, while a fake review tends to be overly promotional or overly negative (as a competitor review).

A positive fake review might highlight the main marketed features of a product, because they’re not actually reviews but marketing gimmicks from people who haven’t tried the product and aren’t concerned about its quality.

5. Consider the Star Rating

Some platforms, stores, and review-based websites allow reviewers to leave star ratings.

Usually, people with varying experiences leave varying star ratings. But most fake reviews give the brand five-star ratings, which is to make buyers think that people are very happy with this brand.

But a five-star rating alone doesn’t make a review fake. When reading, look at other things like the language and date.

If you’re seeing too many reviews with the same date, short descriptions, and five-star ratings, they may actually be fake.

6. Check Reviewer’s Account History

On some platforms, you can check reviewers’ account history, which can be insightful.

If a particular review concerns you, whether it seems fake or real, consider checking the reviewer’s account history. Look for:

• Joining Date: The date they joined the platform.

• Number of Reviews: How many reviews they’ve posted.

• Nature of Reviews: What kind of reviews they previously posted.

If the reviewer’s account is brand new, there’s a chance it’s only created to post fake reviews, even if the review you read is negative, since some competitor brands also post fake negative reviews to smear other brands’ ratings and image.

The number and nature of reviews can also be insightful. A moderately old account might have a few to several reviews of varying nature. But if an account has only one review, or if it has a lot of reviews but they’re overly promotional about the same product or brand, it’s either a fake account, which cannot be trusted, or a self-motivated brand advocate whose advice is biased and unreliable.

7. Check Media or Transaction Proof

Some people attach proof of their purchase in the form of videos or pictures of the product they took with their own phone or the transaction proof, such as an invoice and receipt.

Media images add some credibility to the review, that is, if they’re real. An invoice can also prove that the review is based on a genuine experience. However, attaching fake media is not impossible nowadays with AI tools like ChatGPT.

Until now, people attached media to prove that their reviews were real, but now companies have started to generate fake pictures of their products, which are presented to be taken by reviewers’ phones. So if you’re reading a review, avoid taking the attached media to be real. It may actually be fake, especially if other factors add up.

Transaction proof can also be faked, so take it with a grain of salt as well.

What’s to be trusted is not a single aspect of a review. A review is more trustworthy if most of the above-mentioned factors are on the safe side. However, whether a review is completely genuine or not is impossible to tell. You can only weigh all the factors and be more or less certain.

How to Verify Reviews: Factors Checklist

Here’s a checklist of the factors that make a review more trustworthy:

1. The review is posted on a reliable source.

2. The review is verified by the platform or moderated by community members.

3. The review doesn’t seem to be posted along with many others within a short duration.

4. The review isn’t too short in description and gives some context.

5. The review has a natural language and a neutral stance.

6. The review’s star rating is consistent with its stance.

7. The reviewer’s account history is organic.

8. The reviewer has attached real proof of the transaction or media.

This is how you can verify authentic customer reviews. If a review follows this check list, it’s likely real.

Conclusion

People read online reviews before making a purchase, but that also means their money can go to waste if they end up believing dishonest reviews. That’s why it’s important to verify authentic customer reviews before buying a product. You can narrow down reviews’ authenticity by using a reliable source, checking the dates, examining the language, star rating, reviewer account history, and transaction proof and media.

Checking these factors can help you determine whether a review is possibly authentic or not; however, there’s no fool-proof way to know the genuineness of a review on the internet.
