Every tool on mrreviewai.com has a Trust Score — a number from 0 to 100. Here’s exactly how we calculate it.
The formula
Trust Score = (User Rating × 60%) + (Popularity × 40%)
Two inputs. Nothing hidden.
User Rating — 60% of score
This is the average star rating from real users, converted to a 0–100 scale:
- 5 stars = 100 points
- 4 stars = 80 points
- 3 stars = 60 points
- 2 stars = 40 points
- 1 star = 20 points
We weight this at 60% because direct user experience is the most important signal.
Popularity — 40% of score
This reflects relative traction — how widely a tool is used compared to others in its category. We use a normalized 0–100 scale based on public signals including search volume trends and community mentions.
We weight this at 40% because a popular tool is more likely to be tested across diverse use cases, making its ratings more reliable.
What does NOT affect Trust Score
- Advertising spend — paying us for ads does not move your score
- Commission rate — tools with higher affiliate payouts do not get higher scores
- Featured listing status — a Featured badge is cosmetic only
- Claiming your listing — verification adds a badge but doesn’t change score
Score labels
| Score | Label |
|---|---|
| 85–100 | Excellent |
| 70–84 | Great |
| 55–69 | Good |
| 40–54 | Fair |
| Below 40 | Limited data |
Why we publish the formula
Because you should be able to verify it yourself. Transparency isn’t just a feature for us — it’s the whole point.
