Authentic customer reviews build trust and give potential customers confidence in their purchase decision, but their impact can be undercut by fake reviews. A suspicious number of nearly identical positive reviews can raise red flags for customers, and dishonest bad reviews posted by competitors or trolls can damage your brand reputation.
Research from CapitalOne Shopping shows that an average of 30% of online reviews are fake, and 82% of consumers report encountering fake reviews. If a customer realizes they’ve relied on a fake review of a brand’s products, they’re likely to feel betrayed, and brands can lose business as a result of fraudulent negative reviews.
Read on to learn how you can spot fake reviews, maintain the integrity of your review system, and make it easier for shoppers to buy with confidence.
What are fake reviews?
Fake reviews intentionally misrepresent an experience with a product, service, or business. They may be written to make a product seem better than it really is, unfairly damage a competitor, or manipulate search rankings and marketplace visibility. Fake reviews can come from several sources, including:
-
Automated bots generating a large volume of reviews
-
Paid reviewers who have never used the product
-
Competitors attempting to harm another business’s reputation
-
Businesses creating false positive reviews for themselves
-
Individuals posting reviews in exchange for compensation without proper disclosure
Positive fake reviews can create unrealistic expectations that lead to disappointed customers, and they may also contribute to the sense that a business’s review profile is too good to be true. False negative reviews can discourage legitimate buyers from making a purchase.
How to spot fake reviews
- Look for vague, repetitive language
- Note sudden unexplained spikes in review activity
- Watch for indicators that reviewers are bots
- Pair verified purchases with reviews
- Look for patterns and discrepancies
No single sign proves a review is fake, and not every suspicious review is inauthentic. Since real customers sometimes leave short reviews or award star ratings without much explanation, look for patterns across multiple reviews. The more warning signs you notice, the more closely you should investigate individual reviews.
Follow these steps to spot fake reviews:
1. Look for vague, repetitive language
Fake reviews often rely on generic praise or complaints that could apply to almost anything, such as “Best product ever!” or “Terrible customer service,” without explanation. Fake reviewers tend to be vague because they haven’t actually interacted with the product.
If multiple reviews use identical wording or follow the same structure, they may have been generated by bots and posted as part of a coordinated campaign. It could be a business trying to improve its own image, or a competitor or other bad actor attempting to damage a brand’s reputation.
2. Note sudden unexplained spikes in review activity
A business might naturally receive more reviews than usual after a successful product launch or viral social media post. But if dozens of reviews appear over a short period without an obvious explanation, it’s worth taking a closer look.
A sudden burst of five-star ratings followed by weeks of silence or an unexpected wave of one-star reviews can indicate coordinated activity rather than genuine customer feedback.
3. Watch for indicators that reviewers are bots
Many review platforms let you view a reviewer’s profile or review history. While privacy settings vary, assess account authenticity via warning signs such as:
-
Dozens of reviews posted within a few days
-
Reviews for unrelated businesses across different locations
-
Generic usernames or missing profile information
Although none of these factors alone proves a review is fake, together they can indicate suspicious accounts.
4. Pair verified purchases with reviews
Reviews tied to verified purchases generally carry more weight because they’re linked to an actual transaction. While verification doesn’t guarantee that every review is unbiased, it makes it more difficult for fraudulent actors.
If you sell on Shopify, Shop Product Reviews accepts reviews only from eligible customers who purchased through Shop or a participating Shopify store. Many review apps in the Shopify App Store also let businesses distinguish verified buyers from unverified reviewers, giving shoppers additional confidence in the authenticity of feedback.
5. Look for patterns and discrepancies
A brief five-star review or an unusually negative comment may reflect a customer’s genuine experience. Spotting fake reviews is less about finding one obvious offender and more about recognizing when there’s too much similarity between a wide swath of new reviews. The goal is to identify patterns that suggest reviews may not be authentic.
Customers often leave feedback on Google, Trustpilot, Amazon, and a brand’s own website. If one platform contains overwhelmingly positive reviews while another is filled with unresolved complaints, investigate further.
What to do when you spot potentially fake reviews
- Note unusual activity
- Report suspicious reviews
- Respond courteously
- Encourage authentic reviews
- Use verified review systems
Instead of assuming every questionable review is fake, gather evidence and follow the applicable platform’s reporting process. Here are some strategies you can use to handle this issue when it arises:
Note unusual activity
When a suspicious review catches your attention, start by looking for broader trends. Did multiple reviews appear within a few hours? Are they using similar language or making identical claims? Did they come from accounts with little or no review history?
Cross-reference the reviews with your own records when possible. If someone claims to have purchased a product but there’s no corresponding order—or they’re describing a product you’ve never sold—that warrants further investigation. A good review management system can help you monitor your reviews across all platforms.
Report suspicious reviews
Most ecommerce platforms and marketplaces allow businesses to flag reviews that appear inappropriate or fake. Before reporting a review, gather any relevant evidence, such as order invoices, time stamps, or examples of repeated language across multiple reviews.
If you use a product review app on Shopify, check whether it includes moderation tools or fraud detection features. Many review apps can automatically flag suspicious submissions, identify duplicate content, or require purchase verification before publishing reviews, helping reduce fraudulent activity before it reaches your storefront.
Shopify’s Shop Product Review Guidelines, for example, also establish eligibility requirements and content policies designed to keep reviews authentic and useful for other shoppers.
Respond courteously
Even if you believe a review is fake, avoid responding defensively or accusing the reviewer publicly of being fake.
A calm, professional reply demonstrates that you take customer concerns seriously and are willing to resolve legitimate issues. If the review is genuine, you’ve created an opportunity to rebuild trust. If it’s fraudulent, your response still signals transparency and professionalism to other shoppers. According to BrightLocal research, 80% of shoppers say they’d be more likely to buy from businesses that respond to every review.
Lauren Ludwig, cofounder of Their Jewelry, says on an episode of the Shopify Masters podcast that “one bad review can ruin every single good one that you have.” Her team prioritizes making unhappy customers feel heard, often by quickly offering a refund or replacement.
Although not every genuine negative review can be resolved, responding thoughtfully shows prospective customers that your business stands behind its products.
Encourage authentic reviews
The best defense against fake reviews is a steady stream of genuine customer feedback. Encourage verified customers to leave honest reviews after their purchases, and make the process as simple as possible with automated review requests. Shopify Messaging, for example, allows you to automate post-purchase emails and review requests. Include a direct link to the review form and ask one or two simple questions to prompt customers.
A common and effective review generation practice: offering customers a reward for their honest review. For example, Kloo cofounder Claudia Snow gives customers who leave reviews gifts for their time and effort. “If I get an email asking to leave a review, or do a survey, I will probably ignore it unless there is something in it for me,” she says on Shopify Masters. “We offered our customers free products in exchange for their time.”
Note that Federal Trade Commission rules prohibit incentivizing the sentiment of a given review (whether positive or negative).
Use verified review systems
Verified review programs help establish greater confidence that feedback comes from real customers. While no system eliminates fraud, purchase verification, moderation tools, and clear review policies can significantly reduce fake submissions.
For Shopify merchants, Shop Product Reviews verifies that reviewers have completed eligible purchases before leaving feedback. You can also choose from numerous review apps in the Shopify App Store, many of which offer features like purchase verification, AI-assisted moderation, spam detection, photo and video reviews, and automated review request emails.
How to spot fake reviews FAQ
Why do fake reviews hurt ecommerce brands?
Positive fake reviews may create unrealistic expectations that lead to disappointed customers and more returns, while false negative reviews can discourage legitimate buyers from making a purchase. Both undermine trust, making it harder for shoppers to evaluate products and for businesses to collect honest feedback.
What tools help detect fake reviews?
Many ecommerce review platforms include features designed to identify suspicious activity. Shopify’s Shop Product Reviews, for example, verifies that reviewers have completed eligible purchases before leaving feedback. Third-party product review apps such as Yotpo, Loox, and Judge.me include purchase verification, moderation workflows, spam filtering, duplicate detection, and fraud monitoring to help maintain review quality.
How should businesses respond to suspicious reviews?
If a review appears fake, avoid responding emotionally or accusing the reviewer publicly. Instead, investigate the review, compare it against your order invoices, and report it through the relevant platform if it appears to violate review policies. If the review remains visible, respond professionally and offer to resolve the issue. A thoughtful response demonstrates transparency and customer care, even if the review itself isn’t legitimate.
