Why Amazon Takes Down Legitimate Product Reviews
Amazon's review removal system is a complex, multi-layered mechanism that relies heavily on automated detection systems powered by artificial intelligence and machine learning. Unfortunately, this automated approach frequently results in legitimate reviews being removed alongside fake ones. A problem that has frustrated both customers and sellers for years.
The Core Problem: Automated Detection Systems
Amazon processes millions of reviews daily and relies on sophisticated AI algorithms to detect fraudulent activity at scale. The system uses machine learning models trained on massive datasets from Amazon.com's natural language collection to identify patterns associated with fake reviews. However, these automated systems are imperfect and often flag legitimate reviews as suspicious, leading to removal without human verification.

Before publishing, Amazon's AI analyzes each review for known indicators of fakeness. If a review passes initial screening, it's posted immediately. If suspicious but not definitively fake, it may be flagged for human investigation. The problem is that Amazon's algorithms cast a wide net, and legitimate reviews often get caught in the process.
Automated Pattern Matching:
AI systems are making approval/rejection decisions without human oversight
Patterns that appear suspicious to algorithms but are actually legitimate behavior
Strategies to Prevent Your Reviews From Getting Removed
Here are some approaches to minimize the risk your reviews getting removed:
Review Submission Best Practices:
Do not use AI to write your review
Read the books you choose. Amazon tracks how many pages and how fast you go through the pages.
Don't get a book and immediately review it wait 48 hours after you've spent time reading the book
Review from different IP addresses if multiple household members are reviewing
Don't spend excessive time writing reviews (triggers suspicion)
Never copy/paste reviews or use translation tools
Space out review submissions. Don't post multiple reviews the same day
Clear browser cookies periodically
Never use prohibited words: "fake," "authentic," "fraud," "counterfeit", "AI generated."
Avoid superlatives and extreme language ("best," "worst," "amazing")
Don't mention brand names or competitors
Focus on personal experience using "I" statements, never "you"
Write 30+ words with specific details
Don't mention packaging in product reviews
Never include external links or URLs
Purchase Behavior:
Purchases over $1.99 and higher are likely to be more trusted by Amazon
Pay at least 50-80% of full price to maintain "Verified Purchase" status
Avoid using Amazon gift cards for any portion of payment
Don't use discount codes exceeding 20% off
Ensure spending $50+ total on your Amazon account
Purchasing books at higher prices tends to give Amazon more trust in the review.
Review Timing and Velocity Detection
Amazon rewards consistent engagement over time more than spikes of reviews all around the same time.
The days of piling as many reviews as fast as you can when you first launch and free promo days are not as good as they once were. Amazon has learned that books naturally don't just start getting mass reviews on a new book that just launched, just because it's free. Amazon now grades better on consistent engagement with books over spikes of interest.
When running your free promotions, you might consider breaking up your free promo days. Try to get maybe 5 - 10 reviews. Then wait a few days or a week to do free promo day again to get 5 - 10 more, and so on. This way, it builds history and consistency rather than suspicious spikes.
Amazon's algorithms flag suspicious patterns, including:
Multiple reviews from the same reviewer on the same day
Large numbers of reviews for new products shortly after release
Review surges without corresponding sales data
Reviews posted before delivery confirmation
Review Content Quality Issues:
Reviews deemed too short or lacking detail
Use of "prohibited words" like "fake," "authentic," "counterfeit," "AI generated", or brand names
Mentioning packaging issues (Amazon searches for the word "packaging")
Including external links or URLs
Using superlative language ("best," "most beautiful," "fantastic")
False Positive Detection:
Algorithmic errors flagging legitimate reviews as suspicious
Competitor manipulation: competitors filing legitimate reviews as fake
Similar writing patterns across your own reviews triggering AI detection
Reviews from the same household for different products
System-Wide Purges:
Amazon periodically conducts mass deletions when identifying review manipulation
Legitimate reviews caught in these sweeps are rarely restored
Amazon's review removal system operates primarily through automated AI detection using IP tracking, browser fingerprinting, NLP analysis, and graph neural networks to identify suspicious patterns. While these systems successfully block millions of fake reviews annually, they also remove legitimate reviews through false positives.
The most effective prevention strategy is to use proper purchasing behavior (avoiding IP/device sharing), content optimization (using approved language, personal perspective, adequate detail), and avoid all behaviors that could appear suspicious.
