Online Giants Booking, Trustpilot, Amazon and Expedia Join Forces to Prevent Fake Reviews

Amazon, Booking, Expedia, and Tripadvisor, have come together in a significant collaborative effort to combat the rising menace of fake reviews.

This newly formed coalition, which includes platforms like Glassdoor and Trustpilot, has a shared mission to pool resources and knowledge to thwart fraudsters who deploy AI-driven chatbots to generate misleading online reviews for personal gain. Fake reviews not only tarnish a company's reputation but also mislead consumers into making poor purchasing decisions.

How to Spot Fake Reviews

Spotting fake reviews can be challenging, as fraudsters employ increasingly sophisticated tactics. However, there are several common signs to look for that can help you identify potentially fraudulent or fake reviews:

Overly Positive or Negative Tone: Authentic reviews typically contain a mix of positive and negative elements. If a review is excessively positive or negative without providing specific details, it may be suspicious.

Lack of Specific Details: Legitimate reviewers often provide specific information about their experience. Fake reviews tend to be vague and lack concrete examples or details.

Mistakes in the Wording of Sentences: Watch for unusual or overly formal language in reviews. Fake reviews may be generated by automated systems or non-native English speakers, resulting in awkward phrasing.

Excessive Use of Keywords: Some fake reviews are created to boost a product's search engine ranking. As a result, they might contain an unusual number of keywords and phrases related to the product or service.

Similar Wording Across Multiple Reviews: If you notice multiple reviews using nearly identical language, it could indicate a coordinated effort to post fake reviews.

Unverified Purchases: On e-commerce platforms, check if the reviewer has actually purchased the product. Some fake reviews are posted by individuals who haven't bought or used the product.

Too Many Reviews in a Short Time: A sudden influx of reviews from the same user within a short period may be a sign of suspicious activity.

Inconsistent Information: Cross-reference the information in the review with details from the product or service page. Discrepancies in specifications or features can indicate a fake review.

Same Review Dates: If many reviews were posted on the same day or within a very short time frame, it might be an orchestrated effort to manipulate the rating.

Lack of Verified Purchase Badges: On platforms like Amazon, a "Verified Purchase" badge can indicate that the reviewer has indeed bought the product. While not foolproof, it adds credibility.

Incomplete Profiles: Click on the reviewer's profile to see their review history. If they consistently post overly positive or negative reviews for various products, be cautious.

Use Review Analysis Tools: Several online tools and browser extensions are designed to identify potentially fake reviews. These tools can analyze reviews and provide insights into their authenticity.

Remember that no single sign is definitive proof of a fake review. Genuine reviewers can sometimes exhibit these traits, and fraudsters are becoming more sophisticated. Combining multiple indicators and using your judgment is often the most effective way to spot fake reviews.

The Prevalence of Fake Reviews Powered by Artificial Intelligence Bots is Worrying


A recent government report revealed that fake reviews of products alone could potentially cost UK consumers around £312 million each year. It's estimated that up to 15% of reviews across various e-commerce platforms, particularly in product categories like consumer electronics, home and kitchen, and sports and outdoors, may be fraudulent. As the UK's Digital Markets, Competition, and Consumer Bill is making its way through Parliament, the government intends to employ this legislation to combat the buying, selling, or hosting of fake reviews. The US Federal Trade Commission is also contemplating similar measures.

The increasing sophistication of AI technology has set the stage for an escalating arms race between those who generate fake reviews and the businesses striving to combat them. While some members of the Coalition for Trusted Reviews are already using AI to detect fraudulent reviews, it's crucial to acknowledge that AI could potentially make it easier and more cost-effective to create convincing fake reviews on a large scale.

How Booking, Trustpilot, Amazon and Expedia Are Tackling Fake Reviews

Dharmesh Mehta, Vice President at Amazon, stressed that fake review fraud is a global issue that affects multiple industries. He emphasized that by fostering greater collaboration across industries and sharing information about fraudsters' tactics and operations, the coalition can more effectively combat fraudulent review activity. Ultimately, this will deter bad actors from manipulating online systems and protect consumers.

Travel booking site Tripadvisor, one of the coalition's members, identified a staggering 1.3 million fake reviews on its platform in 2022. According to Becky Foley, a Vice President for the platform, fake review writers often operate in jurisdictions without a legal framework to curtail fraudulent activity. This underscores the critical importance of robust cooperation among companies to tackle the problem effectively.

The Coalition for Trusted Reviews represents a significant step forward in the ongoing battle against fake online reviews. By promoting transparency and information sharing, this initiative aims to protect both businesses and consumers from the detrimental impact of fraudulent content.

Strategies For Booking, Trustpilot, Amazon and Expedia to Combat Fake Reviews


The Coalition for Trusted Reviews must take a multi-pronged approach to combat fake reviews, including:

  1. Implementing Strong User Verification Protocols: Platforms can implement stringent user verification procedures. Users may be required to provide more comprehensive identity information to post reviews. Verification through phone numbers, email addresses, or even social media accounts can significantly reduce fake reviews.

  2. Leveraging AI and Natural Language Processing (NLP) to Improve Authenticity: Leverage advanced AI and NLP algorithms to scrutinize reviews for authenticity. These technologies can detect patterns and anomalies in language, helping to identify suspicious content.

  3. Using Machine Learning Models to Spot Fake Reviews: Develop machine learning models trained to recognize fake reviews. These models can continually adapt and evolve to stay ahead of new tactics used by fraudsters.

  4. Enhancing & Reviewing Validation Services: Collaborate with third-party review validation services. These services specialize in verifying the legitimacy of reviews and can provide an additional layer of protection against fake content.

  5. Reporting and Flagging Systems: Implement user-friendly reporting and flagging systems. Encourage the online community to report potentially fake reviews. Swift responses from platform administrators can prevent fraudulent reviews from gaining traction.

  6. Moderating by Combining AI & Human Oversight: Combine AI with human moderators to oversee reviews. Humans can make nuanced judgments and ensure that AI algorithms are working effectively.

  7. Promoting Transparency Initiatives: Promote transparency regarding review policies and algorithms. Users should have a clear understanding of how reviews are managed and the consequences of posting fake content.

  8. Improving Education: Educate users about the impact of fake reviews and the importance of genuine feedback. An informed user base is less likely to engage in or be misled by fake reviews.

  9. Helping Businesses & Customers with Continuous Monitoring: Regularly audit review content and monitor user behavior. Consistent vigilance is essential in a dynamic landscape where fraudsters continually adapt.

  10. Taking Legal Actions: Pursue legal action against individuals or companies engaged in generating fake reviews. High-profile cases can act as a deterrent.

These strategies, when combined with the core approaches mentioned earlier, provide a robust defense against fake reviews. By embracing a multi-faceted approach, online platforms can better protect the integrity of their review systems and maintain trust among users and consumers.
