A heatmap is a method of reporting where people click, look, scroll or otherwise interact with your website. Heatmaps are frequently used by usability testing tools to easily demonstrate the areas of a web page that have the greatest number of interactions or the lowest number.
The areas with the largest number show up as hot spots and the lowest number show as cold areas, hence the term heatmap.
Heatmaps are a really effective means of displaying this information to allow you to easily see which areas are getting most attention and which are not.
Of 47 usability testing tools in our directory, 20 incorporate heatmaps somewhere in their service.
