A stranger paying a stranger is an act of faith, and that leap is where most marketplace and C2C funnels quietly lose the cautious majority. Answer nine questions about your listing and checkout, and see how well you earn that trust, with the highest-leverage fixes in priority order.
A free tool from Online Hub, a CRO studio for marketplace, C2C and booking platforms in the US, UK and Canada. When you want more than a rough read: Growth Audit Lite ($249, self-serve) or the Growth Audit ($2,500, done for you).

No black box. Nine trust signals, each weighted by how much it moves a stranger toward paying, the weights sum to exactly 100, so your score is the share of trust you've earned.
Each answer scores Yes = full weight, Somewhat = half, No = zero. Score = Σ(weight × answer).
The weights reflect what the evidence says gates conversion between strangers: identity verification, review depth, on-platform payment with buyer protection, real photography, and clear risk-reversal carry the most, because they're what published CRO research and marketplace-abandonment data tie most directly to the leap of faith before payment. Pricing transparency matters because surprise fees are the leading cause of checkout abandonment.
Leaks are ranked by recoverable weight, how many trust points each weak signal is leaving on the table, so the top of the list is genuinely where to start. This is a structured self-assessment, not a measurement; the real numbers come from your own funnel and session data.
You just scored 9 trust signals. Which paid version fits depends on your data. Past 5,000 monthly funnel visitors and 50 monthly conversions, the full Growth Audit reads your real analytics, $2,500. Under that, Growth Audit Lite scores 46 checks across the same nine signals, self-serve, $249.
