Heatmap

A visual representation of where users click, scroll, or move their mouse on a webpage.

Full definition

Heatmaps aggregate interaction data from many sessions into a colour-coded overlay on your page — red and orange areas indicating high activity, blue indicating low activity. Tools like Hotjar, Microsoft Clarity, and Crazy Egg generate three types: click maps (where people click), scroll maps (how far they scroll), and move maps (mouse movement patterns). Heatmaps are qualitative research tools that complement quantitative analytics by revealing the 'why' behind metrics. For example, a scroll map showing only 20% of visitors reach your CTA below the fold is a direct signal to move it higher.

Real-world example

A heatmap reveals users are clicking an image on the homepage expecting it to be a link. Adding a link to that image increases proposal builder visits by 18%.
