What Are Interstitial Ads and How to Use Them Right?

by Chisom Maduonuorah

If you’re using a website and suddenly see a full-screen ad overlapping the page content, you’ve encountered an interstitial advertisement. They are becoming increasingly popular because of their relative effectiveness. This article will explain interstitial ads, how they work, and when to use them.

What is an interstitial ad?

It is an advertising format that covers the user’s whole screen on a browser web page. They fully immerse users into the ad message, unlike Banners that occupy a smaller place or popups that appear randomly. For example, the ad might appear while a user is navigating through a website.

How does interstitial advertising work?

The first step is the user landing on a website. Once they open the page, a request is automatically sent to the publisher’s ad network (e.g., Adsterra) to send an interstitial ad. 

The ad network already has a collection of Interstitials from different advertisers. It detects the user’s screen size and looks for an interstitial page that matches the dimensions. The desktop or mobile interstitial must not exactly match the user’s screen size: anything that fits 50% to 100% of the screen width and 40% to 100% of the height is okay.

Of course, bidding takes place on the ad network. The network then sends the interstitial from the highest-bidding advertiser to the publisher’s website. Once the user takes the required action, e.g., completing a quest on a game, they’ll see the interstitial ad content on their device display.

Why should advertisers use Interstitial ads?

The interstitial ad format offers many advantages for advertisers, including:

1. Engaging

This ad format is more engaging than other formats because it takes up the user’s whole display. It provides an interactive photo or video experience, and readers are more likely to respond to interstitial ads than other formats.

2. Multi-platform compatibility

The interstitial marketing format doesn’t discriminate. It works with all kinds of desktop and mobile devices. You can find it on desktops, Android smartphones and tablets, iPhones, and web browsers. This multi-platform compatibility allows advertisers to reach as many viewers as possible.

3. Higher click-through rates (CTRs)

Interstitial ads have higher click-through rates on average than other ad formats, providing more opportunities for advertisers to get conversions.

How much do interstitial ads pay?

There’s no specific amount a publisher can make from interstitial screen ads. It depends on many factors, including the target audience, content niche, and advertising network. For example, ads from the U.S., U.K., Canada, and other economically developed and emerging countries (e.g., Brazil and Saudi Arabia) return higher payouts.

Some content niches also tend to perform more than others. For instance, Adsterra publishers profit from iGaming, E-commerce, Utility, and Dating offers promoted via Interstitials.

According to an Adnimation study, the average eCPM from Interstitials is 4x that of traditional Banner ads. According to the same study, Interstitials earned publishers an average of $7 to $62 per mille.

Best practices of interstitial ads

  • Use animations when possible. Animated ads are more engaging and generally deliver better results than static image ads. You can use high-quality animations to attract the user’s attention.
  • Offer discounts and freebies to customers. They’re more effective at grabbing customer attention than providing bland information. You can time your discounts to convince customers not to miss out on something valuable.
  • Thoroughly select images and visuals. It’s great when your main visual delivers a clear message, not being just a background pattern or  stock photo. Highlight the main value like in the example below.

  • Ensure you provide a great call to action. No matter how catchy your ad is, some people need a little nudge to take action. So use active verbs and offer value: “shop now,” “get a bonus,” “become a VIP,” etc.

What is the best frequency for capping interstitial ads?

Interstitial ads are good but too many ads can disrupt users’ experience and make them hate your brand as well as the website they navigate. Advertisers must ensure their ads are displayed at healthy intervals.

  • From the advertiser’s side, the best ad frequency is 1 per 24 hours, but it’s possible to increase it to 1 per 12 hours.
  • From the publisher’s side (if allowed by an ad network), it’s better to cap interstitial ads at one per hour for each unique user. This timing ensures that users don’t repeatedly see the same ads.

Interstitial ads can yield great results if you place them well. Adsterra’s Interstitials don’t require any fixed space on your website because they cover the whole screen. Users are likelier to interact with the ad because of full-screen coverage and more so when you find relevant ads from our network.
