A heatmap, in simple words, is a data visualization tool that displays the frequency of interactions on a website or app. It uses a color-coded system. Warmer colors (reds and oranges) indicate higher levels of user engagement, such as clicks, scrolls, or mouse movements. On the other hand, cooler colors (blues and greens) signify less interaction. Marketers and UX designers use heatmaps to understand user behavior and optimize the placement of content, CTAs, or important site elements. They provide a quick and intuitive way to see which areas of a webpage capture the most attention. Thus, it improves both website performance and conversion rates.
