What Percentage of Amazon Reviews Are Fake? (2026)
Short answer: an estimate moves between 7% and 42% depending on whether you count products or reviews — and both of the famous estimators behind those numbers have shut down, so nobody can give you a current figure. Here is what the numbers actually mean, and a free checker you can run on the exact product in front of you.
Believe the reviews, not a statistic

Open the Fake Review Checker →The range, and what each number came from
You will see wildly different figures in search results. They are not contradictory — they are counting different things, at different times, with different definitions of “fake”:
| Estimate | What it counts | Source & status |
|---|---|---|
| 7–11% of products show fake-review patterns | Products, not individual reviews | ReviewMeta (via Review42's summary) — the service has been offline / unmaintained for years, so this is a dated ceiling, not a live census. |
| 30–42% of reviews flagged unreliable | Individual review texts, weighted toward bestseller categories | Fakespot's grading engine — shut down July 1, 2025 when Mozilla discontinued it (announcement May 22, 2025; the Firefox Review Checker feature was actually turned off on June 10, 2025). Not sold or open-sourced — no current successor exists at these numbers' fidelity. |
| >275 million blocked by Amazon in 2024 | Suspected fake reviews Amazon prevented from counting toward ratings | Amazon's own corporate newsroom — also 250+ million in 2023. This is the only first-party number, and it counts blocked activity. |
Why nobody can hand you one number for 2026
Three structural reasons, and they have not changed since the estimates above were made:
- Definition drift. “Fake” can mean fully fabricated reviews, incentivized ones, brand-family employees, or AI-written fluff with real orders behind it. Every estimator draws the line differently, so percentages are not comparable across tools.
- Survivorship. The most visible manipulation (blocked or removed reviews) never shows up in the available data — Amazon, per its own newsroom reporting, blocks hundreds of millions of suspected-fake reviews before they are ever visible, and publishes the number.
- Bright-line rules now apply. Since October 21, 2024, the FTC's fake-review rule makes purchasing or fabricating reviews illegal for US sellers, with per-violation civil penalties. Paid brokers are also a litigation target for Amazon — lawsuits backed by the BBB have targeted operators selling review packages since 2023. Suppression pushes the practice toward subtler forms, which is why checking individual products still matters.
Percentages can't buy for you. Signals can.
For any product — whether its category is 5% fake or 40% — run the same transparent, checkable signals before you trust the star average:
| Signal | Healthy | Check-the-reviews-yourself |
|---|---|---|
| Distribution shape | Spread across 1–5 stars roughly following purchase experience | A wall of recent 5★ with near-zero low ratings |
| Specificity | Mentions actual usage: sizes, sessions, breakage, comparisons | Generic phrases + short superlatives in clusters |
| Timing | Steady trickles over weeks | Bursts of near-identical reviews within days |
| Verified Purchase share | A normal spread (naturally, some buyers bought elsewhere) | ~100% verified does not mean clean, and a low share does not mean fake — verify at the review level, not the aggregate |
These are the exact shapes our free checker evaluates — open it and test any Amazon review page.
Sellers: this burden is yours to prevent
Fake reviews on your own listings are a liability too
If you manage Amazon or Shopify products, fake-positive reviews hurt you more than they help — regulators and lawsuits target them, and returns spike when reality disappoints the inflated promise. Get honest reviews, then see what your real reviews actually say in an evidence-cited report.

What percentage of Amazon reviews are fake?
The honest answer is a range, because it depends on what you count. Independent estimators put it between roughly 7% and 11% of products (ReviewMeta) and 30% to 42% of reviews (Fakespot). Both figures are derelict now: Fakespot shut down in July 2025 and ReviewMeta stopped updating long before, so nobody can give you a current single number.
How many fake reviews does Amazon catch?
Amazon publishes what it blocks, not what gets through. On its own corporate newsroom, Amazon reports proactively blocking over 275 million suspected fake reviews in 2024 and over 250 million in 2023, plus lawsuits against paid-review brokers. Blocked volume says nothing precise about how many past the filters.
Is buying fake reviews illegal now?
In the United States, yes for sellers: the FTC’s rule on consumer reviews and testimonials (16 CFR Part 465) went into effect on October 21, 2024, and it bans buying or writing fake or AI-fabricated reviews, review suppression, and insider reviews without disclosure, with civil penalties per violation.
Are 5-star products with thousands of reviews safe to buy?
Not automatically. A high average with a wall of recent generic five-star praise is exactly the pattern paid-review farms produce. Weight the recent window, look for specifics — usage, duration, photos — and run the reviews through a transparent-signal checker before trusting the aggregate.
