How Is Trustpilot Score Calculated? The Complete Guide

Trustpilot is one of the world’s most influential review platforms, with over 120 million reviews across more than 500,000 businesses. Your TrustScore—a number between 1.0 and 5.0—can significantly impact consumer trust and purchasing decisions. But how exactly is this score calculated?

Understanding the TrustScore Algorithm

The TrustScore is not simply an average of all your star ratings. Trustpilot uses a sophisticated algorithm that considers multiple factors to ensure the score accurately reflects customer satisfaction. Here’s what goes into the calculation:

1. Star Rating Distribution: The core of your TrustScore comes from the percentage of reviews at each star level (1 through 5).
2. Recency of Reviews: Recent reviews carry more weight than older ones, with the most recent 12 months being most influential.
3. Review Volume: Businesses with more reviews generally have more stable TrustScores, as the algorithm has more data to work with.
4. Review Collection Method: Trustpilot differentiates between open invitations (anyone can leave a review) and closed invitations (only invited customers can review).
5. Fraud Detection: Trustpilot’s algorithm includes fraud detection measures to identify and exclude suspicious reviews.

The Mathematical Foundation

While Trustpilot doesn’t disclose the exact algorithm, we can outline the general mathematical approach:

The basic formula resembles a weighted average where:

• 5-star reviews contribute 5 points each
• 4-star reviews contribute 4 points each
• 3-star reviews contribute 3 points each
• 2-star reviews contribute 2 points each
• 1-star reviews contribute 1 point each

The TrustScore is then calculated as:

TrustScore = (Σ(points) / Σ(reviews)) × adjustment factors

The “adjustment factors” include the recency weighting and other algorithmic considerations mentioned above.

How Review Recency Affects Your Score

Trustpilot’s algorithm gives more weight to recent reviews through an exponential decay function. This means:

• A review from last week has full weight (100%)
• A review from 6 months ago might have 50% weight
• A review from 2 years ago might have only 10% weight

This approach ensures your TrustScore reflects your current performance rather than historical data that may no longer be relevant.

Open vs. Closed Invitation Methods

The method you use to collect reviews affects how your TrustScore is calculated and displayed:

Collection Method	Description	TrustScore Impact
Open Invitation	Anyone can leave a review without verification	More susceptible to fraud, but considered more transparent
Closed Invitation	Only verified customers can leave reviews	Less susceptible to fraud, but may be seen as less transparent

Businesses using closed invitations often see a “This company invites its customers” badge on their profile, which can affect consumer perception.

Industry Benchmarks and Comparisons

TrustScores vary significantly by industry. Here are some average TrustScores by sector (based on 2023 data):

Industry	Average TrustScore	% of Businesses with 4+ Stars
E-commerce	4.2	68%
Finance & Insurance	3.8	52%
Travel & Hospitality	4.4	76%
Health & Wellness	4.5	81%
Technology & Software	4.0	63%

These benchmarks can help you understand how your TrustScore compares to competitors in your industry.

How to Improve Your TrustScore

Improving your TrustScore requires a strategic approach to customer satisfaction and review management:

1. Deliver Exceptional Service: The foundation of a good TrustScore is genuine customer satisfaction.
2. Encourage Happy Customers to Review: Implement post-purchase email campaigns asking satisfied customers to share their experiences.
3. Respond to Negative Reviews: Thoughtful responses to critical reviews can mitigate their impact and sometimes lead to updated ratings.
4. Monitor Review Trends: Use Trustpilot’s business tools to identify patterns in negative feedback.
5. Address Common Complaints: If multiple reviews mention the same issue, prioritize fixing it.
6. Maintain Consistent Quality: TrustScores reflect recent performance, so consistency is key.

Common Misconceptions About TrustScores

Several myths persist about how Trustpilot scores work:

• Myth 1: “Deleting negative reviews will improve my score.”
  Reality: Trustpilot only removes reviews that violate their guidelines. You can’t delete legitimate negative reviews.
• Myth 2: “All reviews count equally toward my score.”
  Reality: Recent reviews have significantly more impact than older ones.
• Myth 3: “I can pay to have negative reviews removed.”
  Reality: Trustpilot’s integrity measures prevent this. Attempting to manipulate reviews can result in penalties.
• Myth 4: “A 4.0 TrustScore is bad.”
  Reality: The average TrustScore across all businesses is about 4.1. What’s “good” depends on your industry.

The Business Impact of TrustScores

Research shows that TrustScores directly affect consumer behavior:

• Businesses with TrustScores of 4.0+ see 22% higher conversion rates (Harvard Business Review)
• 89% of consumers read reviews before making purchasing decisions (BrightLocal)
• A 1-star increase in TrustScore can lead to 5-9% revenue growth (Harvard Business School)
• 68% of consumers are willing to pay up to 15% more for the same product from a business with higher ratings (Dimensional Research)

For B2B companies, the impact may be even more pronounced, as business purchasers typically conduct more thorough research before committing to vendors.

Legal and Ethical Considerations

When managing your Trustpilot presence, it’s crucial to understand the legal and ethical boundaries:

• FTC Guidelines: In the U.S., the Federal Trade Commission requires that reviews represent genuine customer experiences. FTC guidelines on fake reviews.
• GDPR Compliance: For businesses operating in the EU, review collection must comply with General Data Protection Regulation requirements regarding customer data.
• Trustpilot’s Terms: Violating Trustpilot’s reviewer guidelines can result in profile suspension.

Ethical review management focuses on:

• Encouraging all customers to share their experiences (not just happy ones)
• Responding professionally to all reviews, positive and negative
• Using feedback to genuinely improve products and services
• Never offering incentives in exchange for positive reviews

Frequently Asked Questions About Trustpilot Scores

How often is my TrustScore updated?

Your TrustScore updates in real-time as new reviews are posted and verified by Trustpilot’s system. However, the visible score on your profile may update less frequently (typically within 24 hours).

Why did my TrustScore drop suddenly?

Sudden drops usually occur because:

• You received several low-star reviews in a short period
• Some older positive reviews aged out of the 12-month recency window
• Trustpilot’s fraud detection removed some suspicious positive reviews
• There was a change in how reviews are weighted in your industry

Can I remove negative reviews?

You can only remove reviews that violate Trustpilot’s content guidelines. These include:

• Reviews containing hate speech or threats
• Reviews with personal information
• Reviews that are clearly fake or from non-customers
• Reviews that violate privacy laws

For legitimate negative reviews, your best approach is to respond professionally and use the feedback to improve.

How many reviews do I need for a reliable TrustScore?

While Trustpilot doesn’t specify a minimum, generally:

• 1-10 reviews: Score may fluctuate significantly with each new review
• 10-50 reviews: Score becomes more stable but still sensitive to new reviews
• 50+ reviews: Score reflects a more accurate picture of customer satisfaction
• 200+ reviews: Score is highly stable and reliable

Does responding to reviews affect my TrustScore?

Responding to reviews doesn’t directly affect your TrustScore calculation. However, it can:

• Encourage reviewers to update their ratings (which then affects your score)
• Demonstrate your commitment to customer service to potential customers
• Provide context that may influence how future customers interpret negative reviews
• Improve your response rate metric, which appears on your profile

Can competitors manipulate my TrustScore?

While rare, competitor manipulation can occur. Trustpilot has measures to detect and prevent:

• Fake reviews from competitors
• Review bombing (sudden influx of negative reviews)
• Impersonation of customers

If you suspect competitor manipulation, you can report it to Trustpilot’s Compliance Team with evidence.

How does Trustpilot handle reviews from free trial users?

Trustpilot considers free trial users as legitimate customers if:

• The trial required sign-up with genuine contact information
• The user actually tested the product/service
• The review reflects a genuine experience

However, reviews from users who never actually used the product/service may be removed as fake.

What’s the difference between TrustScore and the star rating?

The TrustScore (1.0-5.0) is Trustpilot’s proprietary calculation that considers multiple factors including recency. The star rating (1-5 stars) is a simpler average that doesn’t account for these additional factors. Your profile displays both, but the TrustScore is generally more prominent.
