What Is the Difference Between Session Recordings and Heatmaps in Microsoft Clarity?

Session recordings and heatmaps answer two different questions. Session recordings let you watch individual user journeys to see why someone got stuck, while heatmaps aggregate clicks, scrolls, and attention across many visitors to show where people focus or drop off. Use recordings when you need the story behind a single frustrating experience; use heatmaps when you need a pattern across your whole audience. Clarity offers both, and they are designed to be used together rather than as substitutes.

Session recordings: the "why" behind one journey

A session recording replays what a real user did on your site — where they clicked, how far they scrolled, and where they paused or left. According to Clarity's own description, you "watch user sessions, discover where and why users get stuck," and use Highlights to jump to the key moments in each journey.

Best suited for:

• Diagnosing a specific broken flow (a checkout, a signup form, a pricing page).
• Understanding hesitation, rage clicks, or repeated back-and-forth.
• Building a case for a change by showing stakeholders an actual user struggling.

The trade-off: recordings are qualitative and one-at-a-time. You can't watch thousands of sessions, so you use them to explain a problem you already suspect exists.

Heatmaps: the "where" across many users

A heatmap visualizes attention in aggregate — where users click, how far they scroll, and where they place their cursor. Clarity describes it as showing "what users are focusing on, displaying where they click, scroll, and place." You can also compare page versions to see which changes worked and which didn't.

Best suited for:

• Spotting dead zones (content nobody scrolls to) or false affordances (elements people click that aren't links).
• Comparing two versions of a page after a redesign.
• Prioritizing which page or section deserves deeper investigation.

The trade-off: heatmaps show what is happening but not why. A hot spot on a non-clickable element tells you there's confusion, but only a recording shows you what the user expected.

How the two fit together

A practical workflow: start with a heatmap to find a page with an obvious problem (low scroll depth, heavy clicks on a non-interactive element), then open session recordings filtered to that page to watch real users hit the issue. Clarity's AI summaries can shortcut the first pass by highlighting behavioral trends on a page, and AI chat lets you ask questions about your data in plain language instead of digging through dashboards.

What Clarity adds on top

Both features are part of a broader set that Clarity markets as permanently free, used by "over 2 million websites and apps" and "GDPR and CCPA ready." Beyond recordings and heatmaps, the platform includes AI summaries, AI chat, AI visibility (tracking how AI experiences represent your brand), and Brand agents for shopper guidance. Mobile app analysis is available via a lightweight SDK for Android, iOS, Flutter, and React Native.

If your goal is to understand user behavior, the two features aren't competing — recordings give you depth on a few sessions, heatmaps give you breadth across many. Pick based on whether you need to explain a specific problem or find one.
