Microsoft Clarity is free. Ferguson is a paid audit tool. Neither is the right answer in every situation - here’s what each one actually does and when to reach for which.
Audit your landing page →Microsoft Clarity is a behaviour analytics tool that is completely free - no paid tiers, no session limits, no credit card required. You get heatmaps, unlimited session recordings, rage click and dead click detection, custom event tagging, and AI-generated session summaries via Copilot. It integrates with Google Analytics, Google Tag Manager, and has SDKs for Android, iOS, Flutter, and React Native.
Setup takes a few minutes - add the tracking code, and data typically populates within 2 hours. The AI Copilot feature generates natural-language summaries of session recordings, which is genuinely useful for teams that don’t have time to watch hours of footage.
Ferguson is a landing page audit tool. You paste a URL, and within around 3 minutes you get a structured assessment covering headline clarity, CTA structure, social proof, objection coverage, trust signals, and load speed - plus corrected copy in your voice.
No tracking script. No installation. No visitors required. It reads the page as a cold stranger would, which means it works before you have any traffic, and it works on any URL - including competitors’ pages you can’t instrument yourself.
Microsoft Clarity tells you what your existing visitors are doing. Ferguson tells you what’s wrong before your first visitor arrives.
Clarity requires real sessions to show you anything. Ferguson requires none. If you have no traffic yet, Clarity has nothing to analyse. If you already have traffic and want to watch real behaviour patterns, Ferguson won’t tell you where people drop off mid-page.

Use Microsoft Clarity when
Use Ferguson when
Yes. The practical sequence: run Ferguson before launch to catch structural conversion issues before any traffic arrives. Then add Clarity once visitors are flowing - it’s free, so there’s no cost barrier to using both at different stages.
Ferguson reads the page as a cold stranger. Clarity watches what your actual visitors do. Both give you different, genuinely useful information.

Microsoft Clarity is a genuinely impressive product - completely free, no session limits, strong AI features, and easy to set up. If you have traffic and want to understand visitor behaviour, it’s hard to argue against using it.
Ferguson solves a different problem. It tells you what’s wrong with the page before anyone visits - no tracking, no waiting, no setup. If you’re about to launch, about to run ads, or just want to know what a stranger sees when they land on your page, that’s where to start.
