Trustpilot, founded in 2007, is a Danish consumer review platform that hosts 330 million reviews and attracts 60 million monthly active users as of June 2026 [1]. The core question for any engineer or product manager evaluating third-party review data: can you trust Trustpilot? The answer depends on understanding its review verification mechanisms, transparency policies, and known vulnerabilities.

How Trustpilot Collects and Validates Reviews
Trustpilot allows any consumer to submit a review without requiring proof of purchase. This open model increases review volume but introduces noise. The platform employs automated fraud detection that flags suspicious patterns—multiple reviews from the same IP, unnatural language repetition, or sudden spikes in 5-star ratings. Flagged reviews are held for manual moderation. According to Trustpilot’s own documentation, approximately 7% of all submitted reviews are rejected or removed after automated and manual checks. This figure has remained stable over the past three years, suggesting consistent enforcement but not improvement.
The Fake Review Problem and Company Influence
Trustpilot has faced sustained criticism for hosting fake reviews [1]. Companies can invite customers to leave reviews via email campaigns, which can skew ratings toward positive feedback if only satisfied customers are invited. Additionally, businesses can report reviews they believe violate guidelines; Trustpilot then investigates. The platform does not allow companies to directly delete negative reviews, but critics argue the reporting process can be abused to suppress legitimate criticism. In 2023, a Which? investigation found that 12 of 20 top-rated Trustpilot companies had suspicious review patterns, including clusters of reviews from newly created accounts. Trustpilot responded by removing those reviews and updating its detection algorithms.
Flagging a review yourself doesn't always work.
Trustpilot's reporting process is slow and often ends with "no violation found" — even when the review is clearly fake. That's where we come in: we handle the entire removal process, and you only pay for reviews that actually get taken down. Get a quote or message us in the live chat.
Transparency and Data Access for Developers
Trustpilot offers a public API that exposes review data, including star ratings, review text, and timestamps. For engineers building analytics pipelines, this data is accessible but comes with caveats. The API returns only reviews that have passed moderation and are publicly visible. Reviews under investigation or removed are not included, meaning any dataset pulled from the API represents a filtered view. Trustpilot also provides a "transparency report" section on each business profile, showing the number of reviews invited, the number reported, and the number removed. This data is useful for assessing potential bias, but it is self-reported and not independently audited.
Practical Guidance for Evaluating Trustpilot Data
When using Trustpilot reviews for vendor selection or product decisions, apply these filters:
- Review count threshold: Ignore companies with fewer than 50 reviews. Statistical significance improves with volume.
- Recency filter: Reviews older than 12 months may reflect outdated product quality. Trustpilot’s algorithm already weights recent reviews more heavily in its overall score calculation.
- Pattern analysis: Look for clusters of reviews posted within a 24-hour window. Natural review distribution is spread over weeks or months. A spike often indicates an incentivized campaign.
- Response rate: Companies that respond to negative reviews publicly demonstrate engagement. Trustpilot reports response rates per business.
FAQ
Can companies pay Trustpilot to remove negative reviews?
No. Trustpilot’s terms prohibit paid removal of reviews. Companies can purchase subscription plans that provide analytics and invitation tools, but review content is not altered in exchange for payment. The platform’s revenue model is based on subscription fees, not per-review charges [1].
How does Trustpilot detect fake reviews?
Trustpilot uses automated systems that analyze IP addresses, account age, review timing, and language patterns. Reviews flagged by the system are sent to a human moderation team. The company also allows consumers to report suspicious reviews. In 2024, Trustpilot reported that it removes approximately 2.7 million fake reviews annually.
Are all Trustpilot reviews verified?
No. Trustpilot does not require proof of purchase for a review to be published. Verified reviews are marked with a "Verified reviewer" badge, but these account for roughly 35% of all reviews on the platform. Unverified reviews are still displayed but carry less weight in the overall score calculation.
Conclusion
Trustpilot remains a useful but imperfect signal for consumer trust. Its scale—330 million reviews and 60 million monthly active users—provides a broad dataset, but the open submission model introduces noise. For engineers and product managers, the platform’s API and transparency data offer tools to filter and analyze reviews, but independent verification is still recommended for high-stakes purchasing decisions. The trust in Trustpilot is earned not by blind acceptance of its ratings, but by critical evaluation of its data and known limitations.
