Heatmap
A heatmap is a data visualization that uses color gradients to show the relative intensity of user interactions on a web page, with warmer colors (red, orange) indicating areas of high activity and cooler colors (blue, green) indicating low activity.
Also known as: heat map, attention map, interaction map
Why It Matters
Heatmaps make complex behavioral data instantly understandable. Instead of parsing tables of click counts by element or scroll depth percentages, anyone on your team can look at a heatmap and immediately see where users focus their attention and interaction. This visual immediacy makes heatmaps one of the most effective tools for communicating UX insights to non-technical stakeholders.
Heatmaps come in several varieties, each answering different questions. Click heatmaps show where users click (or tap on mobile). Move heatmaps track cursor movement, which correlates with visual attention. Scroll heatmaps show how far down the page users scroll. Each type reveals different aspects of how users interact with your page.
The insights from heatmaps are often surprising. You might discover that users frequently click on elements that are not actually clickable (a sign they expect interactivity), that important content below the fold is seen by only 20% of visitors, or that your carefully designed CTA is being completely ignored while users click on a secondary element.
Industry Applications
A consumer electronics store uses click heatmaps on product pages and discovers that 40% of clicks go to product images (users want to zoom) but only 5% reach the "Add to Cart" button at the bottom. They move the CTA above the fold and add an image zoom feature, increasing conversions by 15%.
A SaaS company uses scroll heatmaps on their pricing page and finds that only 30% of visitors scroll past the feature comparison table to see customer testimonials. They move key testimonials above the comparison table and see a 12% increase in demo requests.
How to Track in KISSmetrics
KISSmetrics focuses on event-based person analytics rather than heatmaps. Complement KISSmetrics with heatmap tools like Hotjar, Crazy Egg, or Microsoft Clarity. Use KISSmetrics behavioral data to identify which pages need heatmap analysis (high-traffic pages with low conversion), then use heatmaps to understand the visual interaction patterns driving those metrics.
Common Mistakes
- -Drawing conclusions from heatmap data with too few sessions - at least 1,000-2,000 sessions are needed for reliable patterns on a typical page.
- -Not generating separate heatmaps for desktop and mobile, which have completely different interaction patterns.
- -Confusing mouse movement heatmaps with click heatmaps - where users hover is not always where they click.
- -Analyzing heatmaps without considering the user segment - first-time visitors and returning users interact differently.
Pro Tips
- +Generate separate heatmaps for each major traffic source and user segment to see how different audiences interact with the same page.
- +Compare before-and-after heatmaps when making page layout changes to verify that user attention shifted as intended.
- +Use scroll heatmaps to determine optimal placement for critical content and CTAs - place them where 70%+ of users reach.
- +Look for click clusters on non-interactive elements as opportunities to add links, tooltips, or interactive features.
- +Combine click heatmap data with A/B test results to understand not just which variant won, but why users interacted differently.

Click Map
A click map is a type of heatmap that specifically visualizes where users click or tap on a web page, showing the distribution and frequency of click interactions across all page elements.
Scroll Depth
Scroll depth measures how far down a web page users scroll, typically reported as the percentage of page length viewed, revealing how much of your content users actually see and where they stop scrolling.
Session Recording
Session recording captures and replays a video-like reconstruction of individual user sessions, showing mouse movements, clicks, scrolling, typing, and page transitions to reveal exactly how users interact with a website or application.
Rage Click
A rage click is a rapid sequence of repeated clicks on the same area of a web page, typically three or more clicks within a short time window, indicating user frustration caused by unresponsive elements, slow loading, or confusing interfaces.
Dead Click
A dead click occurs when a user clicks on a page element that produces no response or navigation, indicating either a broken element, a non-interactive element with misleading visual affordances, or a loading failure.
