As answered by people managing Clerk and Conversion Probe.
Conversion Probe's answer:
Most landing page tools measure performance (speed, SEO, accessibility). ConversionProbe measures persuasion. It runs your page through 7 behavioral psychology frameworks namely Cialdini, Kahneman, Fogg, and more and tells you exactly why visitors leave without converting. You get a scored report with specific fixes. No signup required. The free audit alone gives you a conversion score, blind spots, quick wins, and a first-person visitor perception narrative.
Conversion Probe's answer:
A CRO consultant charges $600-$2,400 and takes weeks. Tools like Hotjar show you what users do but not why they leave. Google Lighthouse scores performance, not persuasion.
ConversionProbe bridges that gap, it gives you the psychology-backed conversion analysis a consultant would deliver, for $29 one-time (or free for the core audit). No subscription, no booking calls, no waiting. Paste a URL, get actionable fixes in 60 seconds.
Conversion Probe's answer:
Founders and marketing teams at early to mid stage companies who know their landing page should convert better but can't justify hiring a CRO consultant. They're data-literate and time-strapped, they've tweaked headlines and button colors based on gut feel and want framework-backed analysis instead.
Conversion Probe's answer:
I've launched products before and watched landing pages underperform without understanding why. Hiring a CRO consultant was too expensive for an early-stage budget, and tools like Lighthouse told me my page was fast but said nothing about whether the copy was persuasive or the trust signals were missing. I built ConversionProbe to give founders the same psychology-driven audit a consultant would run instantly and affordably.
