How Can Exit Intent Technology Detect When Users Are Leaving?
Exit intent technology works by tracking user behaviour that signals an intention to leave a page. On desktop devices, this usually involves detecting rapid cursor movement toward the top of the browser window, which often indicates a tab switch, address bar interaction, or window close.
When this movement is detected, a popup can be triggered before the user exits. This timing allows you to present a final, relevant message while the user is still engaged, instead of after they’ve already left.
On mobile devices, exit intent works differently. Since there’s no cursor, detection relies on signals such as back-button taps, fast upward scrolling, or changes in scroll velocity that suggest a user is about to leave the page.
Exit intent popups are most effective when they present a clear, immediate value. Common examples include a discount code, free shipping offer, or access to a resource in exchange for an email address.
This type of popup gives you one last opportunity to engage users who would otherwise leave, helping reduce cart abandonment and create a follow-up channel through email.
Gleam’s Capture app includes built-in exit intent logic, allowing you to show messages at the right time without needing to install separate scripts or tools.
