What Is an Exit-Intent Popup, and Should You Use One?

An exit-intent popup detects when a visitor's cursor moves toward the browser's close or back button — the moment they're about to leave — and shows one last message before they go.

The logic behind it

The idea is simple: a visitor who's already leaving has nothing left to lose, so a last-second offer, a discount, or a simple "before you go, here's how to reach us" message costs nothing if ignored, and occasionally catches someone who was on the fence.

Why it can backfire

Done poorly — a jarring full-screen popup, hard to close, showing up on every single page — it reads as desperate rather than helpful, and can leave a worse final impression than no popup at all.

When it's worth trying

It tends to work best for businesses with a genuine offer to make — a discount code, a free consultation, a lead magnet — rather than a generic "wait, don't leave" message with nothing behind it.

If you use one, keep it light

A small, easy-to-dismiss message beats a full-screen interruption. And it should never show up more than once per visit — repeatedly popping up for the same person is what actually earns the annoying reputation these get.
