What is TrustScore?
TrustScore is WhoIsAtTop's proprietary measure of a business's overall reputation, calculated from verified customer reviews. It's a number from 1.0 to 5.0 that reflects how reliably a company delivers on its promises.
Unlike star ratings on most platforms, TrustScore is weighted — meaning recent reviews, verified purchases, and businesses that actively engage with feedback all contribute more to the final number. The goal is a score you can actually trust.
How TrustScore is Calculated
Four factors, each weighted to reflect their impact on true customer satisfaction.
Recent reviews carry more weight. A business's reputation today matters more than how it performed three years ago.
The more verified reviews a business has, the more statistically reliable its score becomes.
Businesses that actively respond to reviews — positive and negative — demonstrate accountability.
Reviews confirmed through purchase or service records are given higher weight than anonymous submissions.
What the Numbers Mean
TrustScore bands give you instant context. Whether you're a consumer making a purchase decision or a business benchmarking against competitors, here's how to read the scale.
Why Trust Our Scores?
Three pillars that keep TrustScore independent, tamper-proof, and meaningful.
AI Fraud Detection
Our machine learning models analyze every review for patterns that suggest manipulation, incentivized posting, or fake accounts — and remove them before they affect scores.
No Pay-to-Play
A business cannot pay to improve, hide, or suppress its TrustScore. Every score is calculated purely from real customer data — no exceptions.
Real Customers Only
