AI Insights & Alternatives

Description

A comprehensive overview of this resource

Microsoft Clarity is a free analytics tool that helps website owners understand user interactions on their sites. It records user sessions, generates heatmaps (click, scroll, area), and provides instant replays of user behavior, including rage clicks and dead clicks. This script runs in the browser, capturing events such as mouse movements, clicks, scrolls, and form interactions. This data is then sent to Microsoft's servers for processing and visualization. It aims to help businesses identify user experience issues, optimize website design, and improve conversion rates by understanding how visitors navigate and interact with their content.
