Rewarded Interstitial Ads Explained: How Full-Screen Ads Work and When to Use Them
Rewarded interstitial ads take over the whole screen at a natural pause. See how they work, what makes a good creative, and how to promote a website or app with them.
Banner ads sit at the edge of a screen and people learn to ignore them. Full-screen ads do the opposite: for a moment, your message is the only thing on the display. Rewarded interstitial ads are a popular version of this idea. This guide explains what they are, how they behave on Adloop, and how to build a creative that earns attention instead of irritation.
What is a rewarded interstitial ad?
An interstitial ad is a full-screen ad shown between two moments of an app, such as between levels or before opening a section. The word "rewarded" means the user gets something in return for watching, and the app owner earns from the view. Because the ad is large and clear, the person actually sees it. Because it appears at a natural pause, it interrupts less than a pop-up in the middle of an action.
How the ad behaves on Adloop
On Adloop the ad opens full screen inside a Telegram Mini App. A few simple rules protect both the viewer and the advertiser:
- The close button (✕) stays locked for the first 15 seconds, so the message gets a fair chance to be seen.
- The Continue button cannot be tapped in the first 4 seconds.
- A "Sponsored by Adloop Network" line makes it clear the screen is an ad.
- A view counts only after a full 14 seconds of viewing, timed on our server, so an accidental flash is not billed.
What your creative needs
| Part | Requirement | Why it matters |
|---|---|---|
| Image | Square, at least 600×600, up to 512 KB (GIF up to 1 MB) | Square images fit every phone screen without awkward cropping |
| Title | Up to 60 characters | A short title is read in a glance |
| Description | Up to 120 characters | One sentence that explains the benefit |
| Button text | Choose from presets such as Continue, Install, Open, View, Buy, Subscribe, Play Now!, Join Now!, Follow us! | A clear verb tells the person what happens next |
| Link | Any http or https address | Website, app store page, bot or channel |
How to write a creative that works
- Lead with the benefit, not your company name. "Track your habits in 30 seconds" beats "Welcome to MyApp".
- Use one clear image with one focal point. Busy collages are hard to read on a small screen.
- Keep text on the image minimal, because the title and description are already shown next to it.
- Pick the button that matches the link: Install for a store page, Open for a web app, Join Now! for a channel.
- Make the landing page match the promise. If the ad says free trial, the first screen should show the free trial.
Tip: change one thing per test
Run two versions that differ in only one element, such as the image or the title. When you change one thing, a better result has an obvious cause.
Controls that keep you in charge
You can set a daily budget and a total budget, so spending never runs away. A frequency cap of 1 to 7 views per person per day stops the same user from seeing your ad too often. You can target up to 60 countries, and prices differ for country or region targeting, which you can check on the home page. Every campaign is reviewed by an administrator before it goes live, which keeps the network clean.
Who should use this format
- Mobile app owners who want installs from an audience that already uses Telegram.
- Website and online-shop owners who want visitors from Telegram users.
- Bot, channel and community owners who want new members.
- Brands that want a large, clear moment of attention rather than a small banner.
Honest limitations
A full-screen ad is a strong format, but it is not magic. People are mid-task when they see it, so a vague or irrelevant message will be closed as soon as the button unlocks. Targeting and a clear offer matter more than any trick.
When Adloop is not the right choice
The audience is limited to Telegram Mini App users. There is no built-in install or conversion postback, so measure results with your own analytics and UTM links. Adloop also does not guarantee a fixed number of views, because delivery depends on available audience and your targeting.
Frequently asked questions
Is a rewarded interstitial the same as a video ad?
Not necessarily. "Interstitial" describes the full-screen placement. On Adloop the creative is an image (or GIF) with a title, description and button.
Can I promote a mobile app and not a Telegram bot?
Yes. The button can lead to any http or https link, including an app store page or a website.
How long does review take?
Every campaign is checked by an administrator before going live. Make sure the creative follows the size and text limits to avoid sending it back for fixes.
How do I stop the same person seeing my ad too much?
Use the frequency cap. You can choose between 1 and 7 views per person per day.
