How Our Trust Score Works

A Trust Score is our independent, evidence-based answer to one question: can you safely buy from this platform? We rate every marketplace across five dimensions for a transparent score out of 100 you can check against our published methodology.

3
User FeedbackTrustpilot, BBB, Reddit and app-store sentiment
4

Our methodology is fully transparent — we show our work so you can evaluate our conclusions independently.

Frequently Asked Questions

How does Atop Legal rate online marketplaces?

We score each marketplace from 0 to 100 across five dimensions — infrastructure & security, business legitimacy, user feedback, data protection, and marketplace-specific safeguards such as buyer protection. Each dimension is worth up to 20 points and is based on verifiable evidence rather than opinion. Our full rubric is published on our methodology page.

What does the Trust Score mean?

A higher score means a safer, more accountable platform. 80–100 is Grade A (highly trustworthy), 60–79 is Grade B (trustworthy with care), 40–59 is Grade C (caution advised), and anything below 40 is high risk. The grade tells you at a glance how much to trust a marketplace before you buy.

Are Atop Legal's rankings independent?

Yes. Our Trust Scores are editorially independent and funded by Atop Legal. We may earn affiliate commissions when you visit a platform through our links, but this never changes a score or a ranking, and any sponsored placement is clearly labelled.

How often are the rankings updated?

We review and refresh our assessments regularly as platforms change their policies, security and track record. Every review shows its own last-updated date, and the homepage ranking reflects the latest scores for all 253 marketplaces we cover.
