In today's digital landscape, retaining visitors and reducing bounce rates are paramount for website success. An exit-intent popup is a strategic tool that detects when a user is about to leave your site and presents a compelling message or offer to retain their attention.

This guide will walk you through the process of creating an effective exit-intent popup in Webflow, helping you boost conversions and enhance user engagement.

Today, I will show you how you can create a powerful exit intent popup javascript for any webflow website. In this exit intent popup tutorial you can simply copy and paste the JavaScript code into your Webflow website. This JavaScript can be used in any website be it WordPress, Wix, or any other static or dynamic website.

Let's learn step by step how to do webflow development and website platform development for exit intent popup.

Create Popup in your project

You can create a simple popup design in Webflow similar to below. I won't go into too much detail as I am assuming you already know how to create it in Webflow.

For those who are not using Webflow, you can create a popup in your platform or use the HTML code below to create one.

<div class="exit-popup-modal">
<div class="exit-popup-wrapper">
<h2 class="heading">Heading</h2><a href="#" class="exit-popup-close">X</a>
<p class="paragraph ep-paragraph">Subheading</p>
<a href="#" class="exit-popup-btn">Book a Call</a>
</div>
</div>

All exit popup content will go inside the .exit-popup-modal container. It will have a black transparent overlay.
The .exit-popup-wrapper will have the actual content.

To make it work as a popup, you will also need some CSS.

Design your Exit Intent Popup For Webflow

You can design your pop-up in Webflow using the CSS settings of each element. Use your design sense to make your exit pop-up look prominent for your audience.Let's explore the intricacies of Webflow modal popups and learn how to customize them to align with your brand.

For those who are not using Webflow, you can use the below CSS to design it. I am providing basic CSS to make it look like popup; you can use images or different colors to make it look good.

<style>
.exit-popup-modal {
    position: fixed;
    left: 0;
    top: 0;
    right: 0;
    bottom: 0;
    z-index: 10000;
    display: none;
    border-radius: 0;
    background-color: rgba(0,0,0,.7);
    text-align: left;
 }
 .exit-popup-wrapper {
    position: relative;
    top: 10%;
    bottom: 10%;
    display: block;
    width: 100%;
    max-width: 720px;
    margin-right: auto;
    margin-left: auto;
    padding: 40px;
    background-color: #f6f9ff;
}
</style>

As you can see, I've added a z-index to make sure it appears on top of every other element on the page.

Write JavaScript to make the Exit pop-up work

Now let's add a JaaScript and determine how to show the exit intent popup JavaScript.

We want to detect if the user moves their mouse cursor out of the window. And then we have to use a cookie to determine that the popup won't show all the time mouse cursor moves out of the window.

I have already written the entire exit intent JavaScript for you. You can simply copy and paste the JavaScript to your Webflow inside the Custom Code section of Project Settings.

If you are using it on another platform, you can add this JavaScript in the footer section of your website. Please make sure that the jQuery library is added to the site.

<script src="https://code.jquery.com/jquery-3.6.0.min.js" crossorigin="anonymous"></script>
<script>
/*cookie function - Set and read cookie */
  function createCookie(name,value,days) {
	if (days) {
		var date = new Date();
		date.setTime(date.getTime()+(days*24*60*60*1000));
		var expires = "; expires="+date.toGMTString();
	}
	else var expires = "";
	document.cookie = name+"="+value+expires+"; path=/";
}
function readCookie(name) {
	var nameEQ = name + "=";
	var ca = document.cookie.split(';');
	for(var i=0;i < ca.length;i++) {
		var c = ca[i];
		while (c.charAt(0)==' ') c = c.substring(1,c.length);
		if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
	}
	return null;
}

/* Detecting mouse out event */
  document.addEventListener("DOMContentLoaded", () => {
  document.addEventListener("mouseout", (event) => {
    if (!event.toElement && !event.relatedTarget) {
      setTimeout(() => {
        var ifcookie = readCookie("exitpopup");
    	if(ifcookie !="hide"){
      		$('.exit-popup-modal').fadeIn();
    	}
      }, 100);
    }
  });
});
/* Closing the popup and setting up cookie so it won't show it again.*/
$('.exit-popup-close').on('click', function(){
  createCookie("exitpopup","hide","7"); //You can set any number of days here.
   $('.exit-popup-modal').fadeOut();
});
</script>

Why Use an Exit-Intent Popup?

Exit-intent popups are an effective marketing tool that helps businesses retain visitors and convert them before they leave. Here’s why they work:

• Reduce Bounce Rates: By offering a discount, freebie, or valuable content, you can convince users to stay.
• Increase Conversions: Strategic exit popups can turn abandoning visitors into subscribers or customers.
• Recover Lost Sales: E-commerce stores use exit popups to remind users about their cart or offer a last-minute discount.
• Grow Email Lists: Many businesses use exit popups to collect emails for future marketing campaigns.

Example: Imagine a user browsing your Webflow store, hesitating to buy. Just as they move to exit, a pop-up offers 10% off their first purchase—this small nudge can lead to conversion!

Not all exit popups are effective. Follow these best practices to create a high-converting popup:

1. Make the Offer Irresistible

2. Keep It Simple & Non-Intrusive
   • Avoid long forms—ask for just an email or phone number.
   • Use minimal text with a strong headline & CTA button.
3. Match the Popup Design with Your Brand
   • Use your brand colors and fonts to make the popup feel natural instead of intrusive.
4. Create a Sense of Urgency
   • Use words like “Limited Time Offer”, “Only for the Next 5 Minutes”, or “Expires Soon”.
5. Mobile-Friendly Optimization
   • Ensure the pop-up looks good on mobile devices and doesn’t block important content.
