What is an interstitial Ad? Interstitial ads are a prevalent form of advertising in the digital landscape, particularly within the realm of mobile apps and websites. Unlike traditional banner ads, interstitial ads command the user’s complete attention by occupying the entire screen, making them an impactful and engaging method of conveying advertising messages. Learn about the definition, how it works, benefits, and risks when using this type of advertising through AdsNextGen‘s article below.
1. What is an interstitial ad?
Interstitial ads are akin to pop-up ads but stand out due to their complete screen coverage and potential expandability, known as expandable ads. These ads appear in various forms such as static images, text, rich media, or videos. The timing to close these ads varies by type; static ads typically allow instant closure, while interstitial video ads may have a brief delay of up to 5 seconds before the user can close them. Furthermore, interstitial ads can incorporate playable ads, offering users a glimpse or interactive experience with a game before initiating the download process.

2. How do interstitials work?
Interstitial ads appear at natural break points within an app or website. Such as between game levels. Due to their full-screen coverage and resistance to ad blockers, they may be perceived as intrusive. For this reason, Google enforces penalties for the misuse of interstitial ads.
These ads are interactive, allowing users to decide whether to engage. Clicking on the ad redirects users to the advertiser’s destination, taking them out of the current app or site. Alternatively, users can simply tap to close the ad and continue their activity. While static ads can usually be closed immediately. Video ads may require users to watch for a specified duration, typically around five seconds.
3. Types of interstitial ads
3.1 Interactive Interstitials
Promoted interstitial ads aim to enhance user engagement by allowing advertisers to incorporate them into news sites. Thanks to this, they allow users to interact and give feedback while the platform collects the necessary data.
They represent a dynamic form of advertising that emphasizes encouraging user participation and interaction. This type of advertising reaches users more creatively than traditional advertising.
These ads establish a two-way communication channel, allowing users to actively participate and provide feedback. At the same time, the platform also gains valuable insights.
3.2 Video Interstitials
Interstitial video ads employ brief video clips to convey messages or promotions. For example, YouTube features interstitials that appear before a chosen video, presenting movie trailers or product advertisements. These ads encompass a wide range of content. From featuring upcoming movie trailers and product launches to providing educational material.

4.3 Desktop interstitials
Desktop interstitials work similarly to mobile ads. That is, they are displayed between page views on a desktop site and are subject to equivalent limitations. These interstitials can provide financial benefits to publishers. However, they are not as widely popular as mobile ads. Higher levels of user intrusion and the potential to attract fewer views may limit their returns to advertisers.
5. The benefits of using interstitial ads
5.1 Benefits for Advertisers
- Full visibility: Interstitial ads eliminate the risk of banner blindness because they cannot be easily missed. The full-screen format provides ample space for advertisers to convey their message. They ensure effective communication even on smaller phone screens.
- Increased click-through rate (CTR): Engaged audiences are more likely to click on ads. Thereby accelerating the journey towards transformation.
- Enhanced engagement: When precisely targeted and strategically timed, interstitials offer a significant opportunity to engage audiences. It is for this reason that these ads consistently achieve high impressions and engagement.
- Creative flexibility: A diverse range of formats helps advertisers tell their stories in the most engaging and impactful way, using words, images, videos, or even interactive gaming experiences.
- Extended reach: With interstitial ads not just limited to apps, they offer the potential to connect with audiences across various devices.
5.2 Benefits for Publishers
The above advantages are equally applicable to publishers, whether they own the app or the website. Because together they contribute to increased revenue. Advertisers tend to invest in scale to reach and engage with this audience. At the same time, frequency capping gives publishers significant control over the visibility of their ads, allowing them to command premium prices for their ad space and achieve eCPM (cost-effective per thousand times) healthily.

6. Interstitials best practices
6.1 Ad placement
The timing and placement of your ads is very important. Use A/B testing to ensure that your ads are placed where users naturally pause in your app or on your website.
It is considered best practice to place ads after users have interacted with your website. Instead of interrupting their operations at a critical moment. This is not recommended by Google.
6.2 Ad Frequency
Interstitial frequency is just as important as placement. Avoid displaying ads at all times possible to avoid annoying users. Besides, placing ads needs to comply with Google’s policies as mentioned before. Use A/B testing to determine the optimal frequency to maintain user engagement and satisfaction. Thereby improving both the level of interaction and the ability to retain users.
6.3 Ad design
Although it’s good for users to fully focus on your ad. However, remember that users do not actively choose to view the ad. Therefore, you should design a way for users to exit when they want to exit your ad. You should give users control. Don’t force them to watch long advertising videos or make them struggle to find the X to exit the ad. Thus, new users will have a more favorable view of your ad.

- Risk of penalization: While interstitial ads are integral to game monetization strategies, using them improperly can lead to penalties.

Furthermore, refrain from repetitive ad displays, placing interstitials during app startup or closure, and interrupting gameplay unexpectedly.
