Website overlays, such as pop-ups and slide-ins, are powerful tools for engaging users, delivering targeted messages, and driving conversions.

Based on our own experience, a well-executed overlay can boost conversion rates by as much as 10–25%. However, poorly timed or irrelevant website overlays can have the opposite effect, significantly increasing bounce rates.

If you’re here, chances are you’re seeking ways to integrate website overlays into your strategy effectively, while avoiding common pitfalls.

In this article, we’ll explore real-world examples and proven methods to help you strike the perfect balance between capturing attention and respecting user experience.

Let’s dive in!

What is a website overlay?

A website overlay (also called a popup overlay) is a message or form that appears over the main content of a website.

Its purpose? To grab attention, convey a key message, and encourage users to take action—whether that’s signing up for a newsletter, snagging a discount, or completing a purchase to convert visitors into loyal customers and boost the conversion rate.

They’re typically triggered by user behavior, such as time spent on a page or an attempt to leave the site.

6 popup overlay examples

Curious to see how many users and brands use website overlays to engage visitors and drive conversions?

Here are six standout overlay examples that showcase different styles, designs, and strategies—each one bringing something unique to the table.

1. Hero Pet Health’s fullscreen overlay

A humorous pet photo catches the visitor’s attention, while the headline—“Claim Your 10% Off!”—offers an irresistible incentive. The clear call-to-action (CTA) ensures users know exactly what to do next.

Why it works:

  • Eye-catching design aligned with their playful brand.
  • Simple, actionable language.
  • Clear value proposition: 10% off.
  • Fullscreen design.

  • Minimalist design with high contrast.
  • Low barrier to entry for users (just an email).
  • Perfectly timed for Black Friday shopping.

  • Striking visual appeal.
  • Conversational tone that resonates with customers.

What’s truly great about this overlay is its two-step approach. First, it poses a straightforward yes-or-no question, creating a low-pressure environment for users. Only after users click “Claim 10% Off” does the overlay request their email address.

Why it works:

  • Clean, uncluttered design.
  • On-brand visuals and messaging.
  • A strong, clear CTA.
  • Multi-step popup overlay.

This timely offer creates a final chance to engage and convert departing visitors, seamlessly integrating into the user journey.

Why it works:

  • Smart use of exit-intent technology.
  • Last-minute incentive to capture otherwise lost leads.
  • Simple and direct offer.

6. Supplement Mart’s overlay

  • Builds curiosity with a “mystery discount.”
  • Engages users with a fun, interactive element.
  • Low commitment for visitors.

5 best practices launch high-converting website overlays

Inspired by those great examples and ready to create your own website overlay?

Let’s dive into best practices to make your website overlays engaging and aligned with the customer journey to attract visitors to your site.

1. Target the right audience

Not every visitor is the same, so why show them the same overlay? 

Use behavioral triggers like exit intent or time on page, and segment based on visitor type (first-time visitors vs. returning customers), location, or browsing behavior.

For example, show product-based offers only to users who’ve viewed those products.

2. Clear and compelling messaging

Time is of the essence with overlays. If your message doesn’t grab attention instantly, you risk losing users altogether.

  • Craft a benefit-driven headline: Use concise language to highlight the value, such as “Unlock 15% Off Today” or “Free Guide: Boost Your Productivity.”
  • Be direct and simple: Avoid wordy explanations—users won’t read a paragraph when they’re about to leave your site.
  • Focus on value: Whether it’s a discount, free resource, or exclusive offer, make sure your value proposition is front and center.

3. Relevant offers

An overlay is most effective when it’s personalized. 

Tailor the offer to the visitor’s intent or the page they’re on. For instance, promote free shipping on a checkout page or offer a discount for first-time users on your homepage.

Relevance is key to converting curiosity into clicks.

4. Design for user experience

A visually appealing, user-friendly design can make or break your overlay.

  • Stay on-brand: Incorporate your brand colors, fonts, and imagery to maintain consistency with your overall website design.
  • Prioritize readability: Use large, easy-to-read fonts and sufficient spacing for a clean layout.
  • Highlight the CTA button: Ensure the call-to-action (CTA) stands out with action-oriented language like “Claim Your Discount” or “Sign Up Free.”
  • Avoid overwhelm: Don’t block critical background content or make overlays difficult to close—this frustrates users and reduces trust.

5. A/B test the overlay

Even the best-designed overlay can benefit from optimization. Regular testing allows you to refine your approach based on real user behavior.

Experiment with headlines, visuals, button colors, CTA text, and timing to identify what resonates most with your audience.

Small adjustments, like changing the CTA wording or tweaking the offer timing, can lead to significant improvements.
