Heatmaps show user behavior as color-coded overlays on your pages. Hot colors (red, orange) indicate high activity. Cool colors (blue, green) show low activity. They help identify what users actually do versus what you expect.
What are Heatmaps?
Heatmaps aggregate behavior from many visitors into a visual pattern. Instead of watching individual sessions, you see collective behavior at a glance.
Types of heatmaps:
Click maps: Show where users click. Reveals which elements get attention and which get ignored.
Scroll maps: Show how far users scroll. Indicates where attention drops off and whether key content gets seen.
Move maps (hover maps): Track mouse movement. On desktop, cursor movement often correlates with eye movement.
What Heatmaps Reveal
Ignored elements: Important buttons or links that users don't click may need repositioning or redesign.
False affordances: Non-clickable elements that users try to click suggest design confusion.
Content visibility: Scroll maps show if users reach your call-to-action or key information.
Mobile behavior: Touch patterns differ from desktop clicks. Mobile heatmaps reveal thumb zones and tap accuracy.
Limitations
No "why" information: Heatmaps show what users do, not why. Someone clicking a button repeatedly might be confused, not engaged.
Aggregated data: Individual user journeys get lost. Combine with for context.
Sample bias: Heatmaps from 100 visitors may not represent your full audience. Ensure adequate sample size.
: Pages with , carousels, or modals make heatmap interpretation harder.
Best Practices
Segment your data: Mobile vs desktop, new vs returning visitors, and traffic sources show different patterns.
Set adequate sample size: Wait for at least 2,000-3,000 pageviews before drawing conclusions.
Compare against goals: A button getting clicks isn't always good. Check if those clicks lead to conversions.
Use alongside other tools: Heatmaps work best combined with session recordings and analytics data.
