What action triggers an intercept to appear on a website?

The appearance of an intercept on a website is often based on user behavior that indicates they might be disengaging from the content or leaving the site entirely. When a user moves their cursor outside the viewing area, it typically signifies that they are either focused on closing the tab or navigating away from the page. This action can initiate a prompt intended to capture the user's attention, such as an intercept aimed at gathering feedback or offering assistance before they leave.

This behavior aligns with user experience strategies where website designers want to engage visitors who show signs of exit, providing an opportunity to retain them or gather valuable insights into why they are considering leaving. The other options, while they may trigger some interactions, do not specifically indicate a decline in engagement like moving the cursor outside the viewing area does.
