In the fast-paced digital era, trust is the foundation of every successful online transaction.
Reviews and ratings are critical tools for building and maintaining this trust.
For marketplaces, they aren’t just nice-to-have features—they’re fundamental for long-term success.
This article dives into why reviews and ratings matter, explores the challenges marketplaces face, and highlights strategies to maximize their effectiveness.
The Role of Reviews and Ratings in Building User Trust
Establishing Credibility
Reviews and ratings serve as social proof, confirming the reliability of products, services, or sellers.
- According to BrightLocal, 79% of consumers trust online reviews as much as personal recommendations.
- Positive feedback reassures potential buyers about the quality of their purchase.
Reducing Risk for Buyers
Online transactions inherently involve risk. Reviews help mitigate this by:
- Offering insight into product quality, service reliability, and seller behavior.
- Highlighting potential issues through negative reviews or low ratings.
Enabling Informed Decision-Making
Reviews empower users to make better choices:
- They highlight strengths and weaknesses of options.
- They offer firsthand insights from past customers, enhancing buyer confidence.
Challenges in Implementing Effective Review Systems
Fake Reviews and Ratings
Fake reviews undermine user trust, with research showing that 82% of consumers have encountered fake reviews (Trustpilot).
Solutions:
- Deploy AI tools to detect review authenticity.
- Encourage verified purchases to ensure genuine feedback.
Review Bias
Positive experiences often go unreported compared to negative ones. This imbalance can skew perceptions.
Solutions:
- Incentivize reviews with discounts or loyalty points.
- Use automated post-transaction emails to request balanced feedback.
Low Engagement Rates
Some users are hesitant to leave reviews, limiting valuable insights.
Solutions:
- Simplify the review process (e.g., star ratings with optional text).
- Provide clear prompts like "What did you love about your experience?"
The New Rules for Reviews: What US and UK Law Require of Marketplaces Since 2024
When this article was first written, fake and bought reviews were mainly a trust problem. Today they are also a legal one, and some common tactics, including the discounts-for-reviews idea above, need care.
Consumers trust reviews less, but read them more
BrightLocal's 2026 Local Consumer Review Survey (1,002 US adults, February 2026) found that only 49% of consumers trust online reviews as much as personal recommendations, far below the figures quoted a few years ago. Yet 97% read reviews when choosing a local business, 41% "always" do, 74% focus on reviews from the last three months, and 31% will only use businesses rated 4.5 stars or higher. The same survey found that 45% now use ChatGPT and other AI tools to get local recommendations, up from 6% a year earlier.
United States: the FTC Consumer Review Rule
The FTC's final rule, announced in August 2024, prohibits:
- Fake reviews, including AI-generated ones, and reviews from people with no real experience of the product
- Incentives conditioned on a positive (or negative) review
- Undisclosed reviews by owners, managers or employees
- Company-controlled websites that claim to offer independent reviews
- Suppressing negative reviews through unfounded legal threats or intimidation, or claiming the reviews shown are all the reviews received when negative ones were held back
- Knowingly buying or selling fake followers or views
Knowing violations can bring civil penalties of up to $53,088 per violation, and the FTC sent warning letters to 10 companies in December 2025.
United Kingdom: the DMCC Act
Since 6 April 2025, the Digital Markets, Competition and Consumers Act bans fake reviews, concealed incentivised reviews and misleading presentation of reviews, such as cherry-picking positive reviews or showing reviews of a different product. Anyone who publishes reviews, which includes a marketplace, must take "reasonable and proportionate steps" to prevent and remove them, and the CMA can fine up to 10% of global turnover (CMS summary, April 2025).
A practical checklist for marketplace owners
- Ask everyone, reward no one for a rating. If you offer loyalty points for reviewing, give them for any honest review, and label incentivised reviews clearly.
- Restrict who can review. Reviews tied to a real transaction are harder to fake. Never let sellers review their own listings.
- Publish a review policy that says how you detect fakes, what you remove and why, and keep a record of removals.
- Don't hide bad reviews. Removing genuine negative reviews, or presenting the reviews you show as all the reviews you received, can itself break these rules.
- Disclose staff reviews and keep employees and relatives from reviewing anonymously.
If you run your marketplace on Yclas, the reviews feature can be limited to users who actually bought the item, and it already blocks users from reviewing their own ads.
Proven Strategies for Optimizing Review and Rating Systems
Use Verified Reviews
Verified reviews ensure feedback comes from actual users.
- Platforms like Amazon and Airbnb prominently display “Verified Buyer” or “Verified Guest” tags.
Introduce Moderation Tools
Manual or automated moderation filters inappropriate or irrelevant feedback.
- Examples: AI-driven tools that detect offensive language.
Highlight Average Ratings and Review Counts
Showcasing the average star rating and number of reviews builds credibility.
- Example: Restaurants on Google Maps display a star rating alongside the number of reviewers.
Incorporate Visual Elements
Allow users to upload photos or videos with their reviews to add authenticity.
- Example: eBay encourages photo uploads for reviews to verify product conditions.

Handling Negative Feedback
Negative reviews can damage reputations but also present opportunities for improvement.
Solution: Train sellers or service providers to respond constructively, turning dissatisfied customers into loyal ones.
The Bottom Line: Why Reviews and Ratings Are Indispensable
