This metric is crucial for web performance optimization as it directly affects user experience. When a page is blocked, users cannot interact with it, which can lead to frustration and ultimately a high abandonment rate. Total blocking time occurs when the main thread of the browser is busy processing tasks, such as executing scripts or manipulating the DOM, preventing input events like clicks or scrolls from being responded to. Extended blocking time can result from heavy scripts, resources that take time to load, or poor management of asynchronous tasks.
