Heatmaps are tools that show where people click, scroll, or move their mouse on a website. They use colors to show activity, with warmer colors showing more action. This helps you see what visitors pay attention to and what they ignore. For example, if many people stop scrolling before reaching a call to action, that section may need to move higher. If users keep clicking on something that is not a link, it may confuse them. These insights help improve layout and content. How useful do you find visual data like this?
