Heatmap
Definition
A heatmap visualizes intensity or frequency over positions or categories using a color scale.
In the UX context, heatmaps aggregate, for example, clicks, scroll depth, or interactions. They show patterns but do not automatically explain the cause of user behavior.
Simply explained
Like a thermal image map where frequently used areas are highlighted more strongly.
Why it matters in practice
Relevant for UX analysis and hypothesis formation when quantitative interaction patterns on pages are to be made visible.
Example from business
A landing page shows many clicks on a non-clickable element; the team checks whether users expect an interaction there.
Limits and pitfalls
- Interpreting colored areas as proof of cause; ignoring sample size and device types; overlooking data protection and consent; using heatmaps without qualitative analysis.
Origin & history
Heatmaps are a general form of visualization. Web analytics tools have popularized them as aggregated click, scroll, and area maps for UX analysis.
Use in mid-sized companies
- Possible application: examining navigation, CTA placement, scroll behavior, and conspicuous misclicks on important pages.
Frequently asked questions
