What is an exit-intent popup and does it work?

An exit-intent popup is a message shown when software guesses a visitor is about to leave, usually an email signup or a discount. It can work on pages where visitors already have a reason to be interested, such as pricing, a cart or a lead-magnet page, and where a small offer fits what they came for. It rarely helps on pages where the visitor has not yet seen what you sell, and on mobile the "exit" is a guess based on other signals.

How to do it

1. Choose pages with intent. Pricing, checkout, a product page or a long guide are good candidates. Skip the home page and anything a first-time visitor lands on from search.
2. Match the offer to the page. On a pricing page, offer a short call or a trial extension. On a guide, offer the checklist version. A generic "subscribe to our newsletter" gets ignored.
3. Pick the trigger. On desktop, tools watch the pointer. Popup Maker's documentation says its "Mouse Leave" method detects when you move the pointer "outside of the top edge of the browser window" and is desktop only. Its other methods, such as Lost Browser Focus (changing tabs or apps) and Back Button (the first back click shows the popup, a second click goes back), are marked compatible with desktop and mobile (Popup Maker docs).
4. Limit repeats. The same documentation advises using the exit-intent trigger with a cookie "to prevent annoying your visitors". Show it once per visitor, and never right after they dismiss it.
5. Ask for the minimum: one email field and a clear button. Say what they get and how often you will email.
6. Test it. Show the popup to half of eligible visitors and compare signups, purchases and bounce between the two groups. A popup that collects emails but lowers purchases is a loss.

What it looks like in practice

Say you sell a $79 project template pack. A visitor reads the pricing page, then moves the pointer to the tab bar. A small box slides in: "Not sure yet? Get the free starter template and one email a week." They enter an address and receive the file. You compare two weeks with and without the box. You count paid orders as well as signups, because the goal is customers, not a longer list. This is a hypothetical setup with no results attached.

When it backfires

• Google's interstitial guidance. In 2016 Google said that after January 10, 2017, pages where content is not easily accessible on arrival from mobile search "may not rank as highly". Its examples included "a popup that covers the main content, either immediately after the user navigates to a page from the search results, or while they are looking through the page". Interstitials responding to a legal obligation, such as cookie use or age verification, were listed as acceptable (Google Search Central blog). Keep mobile popups off the arrival moment.
• Consent rules. Under GDPR, "silence, pre-ticked boxes or inactivity should not therefore constitute consent", and a consent request must be "clear, concise and not unnecessarily disruptive" (GDPR Recital 32). If you sell to people in the EU or UK, do not pre-tick a marketing box.
• False triggers. Pointer-based triggers fire when someone just reaches for a tab. Popup Maker offers a "false positive delay" setting for this reason.
• Annoyed visitors. A popup on every page view teaches people to close it without reading.
• Wrong metric. More email signups do not mean more revenue. Judge it by orders.

Questions people ask

What is exit intent? A trigger that guesses a visitor is about to leave, often from the pointer moving toward the browser's top edge, and shows a message at that moment.

Does exit intent work on mobile? There is no pointer on a phone, so tools use other signals such as the back button or switching apps. Treat results as separate from desktop and test them on their own.
