For Desktop Devices

Mouse Movement Detection

How it works:

• We track where the mouse cursor moves on the page.
• When the mouse moves to the very top of the browser window (within 15 pixels), it indicates the user is about to close the tab or window.
• We can show a message or offer before they leave.

Why this works:

• When users want to close a tab, they typically move their mouse to the top where the close button (X) is located
• The browser's address bar, tabs, and close buttons are all at the top
• Moving the mouse to the top is a strong indicator of exit intent

Technical Details:

• Monitors mouse position continuously
• Triggers when mouse Y-coordinate is ≤ 15 pixels from the top of the viewport
• Very reliable on desktop devices with mouse/trackpad

For Mobile Devices

Back Button Detection

How it works:

• When a visitor arrives from another site (e.g., Google, Facebook), we prepare the back button.
• If they tap the browser back button, we treat it as exit intent.
• We can show a message or offer before they leave.

Technical Details:

• Uses the browser's History API to detect back button presses
• Works by adding a state to browser history and listening for popstate events
• Only activates when user arrives from an external site (not from same domain)

Scroll-Up Detection

How it works:

• We track how far they've scrolled down the page.
• If they scroll down, then quickly scroll back to the top (0% scroll position), it may indicate they're about to leave.
• We can show a message or offer.

Technical Details:

• Monitors scroll position continuously
• Detects when user scrolls from a position > 0% back to 0% (top of page)
• This upward scroll gesture often indicates intent to leave

Common Method: Tab Switch Detection

Applies to: Both Desktop and Mobile

How it works:

• We detect when the user switches away from the current browser tab or window.
• On desktop: When they switch to another tab or minimize the browser.
• On mobile: When they switch to another app, go to home screen, or switch to another browser tab.
• We can show a message or offer when they're about to leave.

Technical Details:

• Uses the browser's visibilitychange event
• Fires when the page becomes hidden (user switches away)
• Works across all modern browsers on both desktop and mobile
