Format Selection Guide

A rectangular ad displayed in a fixed area. The most common format, typically shown as a strip at the top or bottom of the screen. Sizes All sizes support video creatives. For more details, see Video Ad Units. Using a template automatically applies background and padding around the ad creative. It naturally fills empty space when the creative size is smaller than the Ad Unit. Background Color If not using a template, you can set the background color directly. Choose a color that matches your app or website design. When multiple campaigns are running, carousel is activated to rotate ads. Ads are displayed in random order to prevent performance concentration on the first ad.
Video banners cannot use carousel.
Carousel Activation Select whether to use carousel when creating an Ad Unit. Indicator Display Shows which ad is currently displayed. Appears in the bottom right as “current position/total count” format (e.g., 1/3). Rolling Time The interval at which the carousel automatically switches. Default is 3 seconds, with 3-4 seconds recommended per ad. Operation Policy
While it seems efficient to show multiple ads in limited space, actual monetization data and user psychology show it’s not as effective as expected. Viewability Decline Only the first slide has exposure effect. Users quickly scroll without waiting 3-5 seconds for the next slide. Later ads load but aren’t actually seen, creating ‘phantom impressions’ that can lower bid prices over time. Divided Attention CTR is highest when a single static banner delivers a clear message. When images constantly change and multiple messages roll, users feel fatigued by information processing and tend to look away. Banner Blindness Users tend to recognize ‘moving sliders’ as ad areas and ignore them. Visibility is lower compared to native ads that naturally blend into content. Recommended Alternatives
Carousel has good ‘space efficiency’ but poor ‘ad efficiency (revenue)’. If maximizing revenue is your goal, we recommend single banners.

​
Close Options

Close by Tapping Outside Outside Area Background Brightness Adjusts darkness of background behind popup. Choose from 80 (dark), 55 (medium), 30 (bright). Don’t Show Today When multiple campaigns are running, ads rotate in carousel format. Carousel Display Count Limit
Limiting carousel count to 3-4 increases user focus and improves CTR.
Display Priority When available ads exceed carousel limit, they are selectively displayed based on the following priority.
If carousel limit is less than sold slots, ads are randomly selected for display. As carousel count increases, ad efficiency decreases, so we recommend adjusting slot count to match carousel limit.

​
Native

An ad that naturally blends with app or website content design. Article-style ads in news feeds are typical examples, with freely customizable UI. Sizes

​
Native Default Fields

Default fields recommended for better ad performance.

​
Native Additional Fields

Custom fields can be set for additional information like background color, tags, posting date, engagement metrics.

​
Native Options

AD Mark Display Displays ‘AD’ watermark at top right of ad so users recognize it as advertising. If disabled, users may not recognize it as an ad. Accept Dark Mode Creatives When enabled, you can accept creatives for dark mode.

​
Interstitial

A full-screen ad covering the app/web screen. Typically exposed when user activity temporarily stops, such as when a game level ends or page transitions. Sizes

​
Close Button Delay Time

Sets time until close button appears after ad is displayed. Users cannot close the ad during delay time, so set appropriate time to balance ad effectiveness and user experience.
High exposure, CTR, and conversion rate are advantages, but displaying too frequently can harm user experience (UX).

​
Rewarded

An ad that encourages video viewing in exchange for in-app rewards. When users watch the ad to completion, rewards such as items, points, or lives are provided. Frequently used in mobile games. Size
