How to Use Heatmaps for Conversion Rate Optimization

The Three Types of Heatmaps and What Each Tells You

Heatmaps visualise aggregate user behaviour across hundreds or thousands of sessions overlaid on a screenshot of your page. Each type answers a different question about user attention and engagement. Understanding which question to ask is what makes heatmap analysis useful rather than just interesting.

Click Maps: Where Attention Actually Goes

Click maps show where users click. The most valuable insight from click maps isn't where users do click — it's where they don't click, and where they click on elements that aren't clickable.

Common click map findings:

• Non-clickable element clicks: Users clicking images, icons, or text that looks interactive but isn't → add a link or remove the visual cue
• CTA neglect: Your primary button receives very few clicks relative to its prominence → likely a copy, colour, or placement problem
• Navigation vs. CTA clicks: Users preferring navigation links over page CTAs → users are not ready to convert, need more information first

Scroll Maps: What's Actually Being Seen

Scroll maps show what percentage of users scroll to each point on the page. The key insight: any content below the 50% scroll depth is seen by fewer than half of visitors. This has major implications for page design.

If your primary CTA is below where most users stop scrolling, they never see it. If critical social proof or product benefits are in the bottom 20% of a long page, they're almost invisible. Scroll maps make these visibility problems immediately apparent.

Use scroll maps to find the "fold" — the point where the majority of users stop. Ensure the most important elements (hero CTA, key value proposition) appear well above this point.

Move Maps: Attention Proxy

Mouse movement correlates loosely with eye movement — where users move their mouse tends to be where they're looking. Move maps show concentration of mouse attention. Use them to validate that your key design elements are drawing attention, and to spot unexpected attention patterns (users focusing on an image next to an ignored CTA rather than the CTA itself).

Segmenting Heatmaps

The highest-value heatmap analysis segments by device type (mobile vs. desktop) and by user segment (new vs. returning, or by traffic source). A desktop heatmap showing strong CTA engagement may hide a mobile heatmap where the CTA is off-screen. Always review mobile and desktop heatmaps separately — they often tell completely different stories. Our CRO service starts every engagement with a structured heatmap audit.
