The Fake Review Epidemic
Online reviews have become the backbone of e-commerce decision-making. Over 90% of consumers read reviews before making a purchase, and most trust them as much as personal recommendations. This trust has created a lucrative target for fraudsters — and AI has made their job easier than ever.
The AI Shift
Before ChatGPT, fake reviews were often obvious — poor grammar, generic language, or clearly outsourced to non-native speakers. Now, AI can generate hundreds of unique, grammatically perfect reviews in minutes, each with different details and writing styles.
Fake Reviews by Platform
Different platforms have varying levels of fake review problems and detection capabilities. Here's how the major review platforms compare:
| Platform | Fake Review Rate | AI-Generated | Platform Detection |
|---|---|---|---|
| Amazon | 38% | 24% | Moderate |
| Google Reviews | 42% | 31% | Low |
| Yelp | 25% | 18% | High |
| TripAdvisor | 34% | 22% | Moderate |
| App Store | 29% | 19% | Moderate |
| Trustpilot | 31% | 21% | High |
Spot the Difference
Can you tell which review was written by AI? Here's a side-by-side comparison showing the key differences between AI-generated and genuine reviews:
“This product exceeded all my expectations! The quality is absolutely amazing and the shipping was incredibly fast. I would highly recommend this to anyone looking for a top-notch solution. Customer service was also very helpful and responsive. Will definitely be purchasing again!”
“Bought this for my home office. The 32-inch size is perfect for my desk setup. Colors are accurate which matters for my design work. Only complaint is the stand is a bit wobbly - had to add a book underneath. Otherwise solid monitor for the $280 price point.”
10 Signs of AI-Generated Reviews
While AI-generated reviews are becoming more sophisticated, they still leave telltale signs. Here are the key indicators to watch for:
Excessive Superlatives
AI tends to overuse words like 'amazing,' 'incredible,' 'absolutely,' and 'definitely.'
“This is absolutely the most incredible product I've ever purchased!”
No Specific Details
AI reviews often lack specific product features, measurements, or use cases.
“The quality is great and it works exactly as described.”
Perfect Grammar
Ironically, perfect grammar with no typos or casual language can be a red flag.
Formulaic Structure
AI often follows a pattern: positive opening, feature mention, recommendation closing.
Lack of Personal Context
No mention of why they bought it, how they use it, or their specific situation.
Unusual Timing Patterns
Many reviews posted within hours or days, especially after product launch.
Reviewer Has No History
Account created recently with only reviews for similar products or same seller.
All 5-Star or 1-Star
Real users give varied ratings; AI campaigns often are all-or-nothing.
Generic Photo or No Photo
Stock images, product photos from listing, or no images at all.
Doesn't Match Product
Review mentions features the product doesn't have or wrong product category.
Most Affected Industries
Some product categories are more heavily targeted by fake review campaigns than others. Understanding which industries have the highest fake review rates helps you know when to be extra vigilant.

Use AI tools to analyze incoming reviews for signs of fake negative reviews from competitors.
Document and report fake reviews to platforms — most have dedicated fraud teams.
Make it easy for real customers to leave reviews through follow-up emails and incentives.
Respond to all reviews — this shows engagement and helps identify patterns in fake reviews.
