Maximize Your Website Revenue with the Right Ad Formats. Monetizing your website effectively requires the right balance between ad revenue and user experience. With Popunders, Interstitials, and In-Page Push Ads, you can boost earnings without disrupting your audience.

Monetizing a website isn’t always straightforward. With so many ad formats, settings, and strategies, it’s easy to feel like you’re missing out on potential earnings—or worse, hurting user experience without realizing it.

If you’ve ever wondered which formats actually work, how to use them without annoying visitors, or how to make the most of your traffic, you’re not alone. In this guide, we’ll break down three effective ad formats—Popunders, Interstitials, and In-Page Ads—and show you exactly how they work.

To make things clearer, we’ve included screenshots and examples, so you can see everything in action and confidently set up your monetization for higher revenue and better results.

Let’s get started.

Popunder Ads: The Classic Revenue Booster

Popunders are one of the most well-known ad formats in the monetization game. When a user clicks on your site (or even just visits it, depending on the setup), a new tab or window opens in the background with an advertisement.

Why Popunders Are Great for Publishers:

  • High CPMs — advertisers love this format, meaning higher payouts.
  • Doesn’t interrupt user experience — visitors continue browsing as usual.
  • Works well alongside other monetization methods.

Typical Offers in Popunders:

  • E-commerce deals and promotions
  • Online courses and educational content
  • Subscription services and digital memberships
  • Financial products and investment services

Pro Tip: To keep your bounce rate low, set popunders to trigger after user interaction (like scrolling or clicking). This way, they feel less intrusive and still bring in solid revenue.

Interstitial Ads: Full-Screen Impact

Interstitials are full-page ads that appear between content transitions—like when a user navigates to a new page or before they access your main content. These are high-impact and great for advertisers looking for strong visibility.

Why Interstitials Are Great for Publishers:

  • High engagement means high earnings per impression.
  • Works well with mobile and desktop traffic.
  • Can be optimized to minimize disruption.

Typical Offers in Interstitials:

  • Subscription services (e.g., streaming platforms)
  • Finance and investment opportunities
  • Online retail promotions and discounts
  • Event registrations and webinar sign-ups
  • Travel deals and flight booking promotions

Pro Tip: Don’t overuse interstitials—triggering them too often can annoy users. A good rule of thumb? 1 per session or after meaningful engagement.

In-Page Push: A Native-Looking Alternative

Unlike traditional push notifications, In-Page Push Ads (IPP) appear directly inside your website, blending in naturally with the content. They’re non-intrusive and work well for users on all devices, including iOS (which doesn’t support traditional push ads).

Why In-Page Push Is Great for Publishers:

  • Additional revenue stream without disrupting user experience.
  • Works on iOS & Android (unlike traditional push).
  • Blends seamlessly with your content, making it feel like a natural part of your website.

Typical Offers in In-Page Push:

  • E-commerce promotions and discounts
  • Survey and market research campaigns
  • Job recruitment and hiring ads
  • Lifestyle and wellness product promotions
  • Local services and home improvement deals

Pro Tip: Test different placements. Some publishers see the best results when placing IPP near high-engagement areas (e.g., after articles, near CTA buttons).

How to Use These Formats Together

Here’s where the magic happens: combining these formats strategically can boost your revenue without overwhelming your users.

Example Setup for Mainstream Publishers:

  • Popunders: Best triggered when a user is about to leave (exit intent) or after meaningful engagement (e.g., clicking a button or link). This keeps them less intrusive while still generating strong revenue.
  • Interstitials: Place them at natural transition points, like when a user navigates to another page or after reading an article. This way, they get high visibility without interrupting the flow of browsing.
  • Works as a low-impact, always-on revenue stream. Since it blends with your content, it provides steady earnings without distracting users. You can customize the content based on user behavior—for example, showing shopping-related offers to users visiting e-commerce pages.

A crucial part of ad monetization is finding the right balance. Too many ads can chase users away, but too few means missed revenue opportunities. When using multiple formats on a page, it’s essential to test different frequencies and placements to see what works best for your audience without disrupting their experience.

Fine-tuning ad strategy is what separates average monetization from great monetization—so keep testing, adjusting, and optimizing!

Advanced Tip: Many successful publishers customize ad frequency based on user behavior (e.g., limiting interstitials for returning visitors while keeping popunders always available for new users).
