Heatmapping: is a data visualization tool that shows where users have clicked, scrolled, or moved their mouse on your website. It uses colors to represent different levels of activity - warm colors like red and orange signify areas where users interact the most, while cool colors like blue signify less interaction. They help to analyze how effective your webpage is, showing you what parts of your page are getting the most attention and where users are ignoring, thus providing insights on how to improve user experience and conversion rates.
