Banners also 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.
SituationBehavior
Multiple CampaignsCarousel is created and ads rotate during display
Single Campaign with Multiple CreativesCreatives are randomly displayed at equal rates without carousel
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

Activation ConditionCarousel operates only with 2 or more ads
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
MethodDescription
Single BannerDisplay the best-performing ad permanently to improve CTR
Add Separate Ad UnitsAdd Ad Units in different locations instead of carousel to secure exposure opportunities
Carousel has good ‘space efficiency’ but poor ‘ad efficiency (revenue)’. If maximizing revenue is your goal, we recommend single banners.

​

OptionDescription

Don’t Show This Ad TodayDon’t display only this campaign for today
When multiple campaigns are running, ads rotate in carousel format. Carousel Display Count Limit
SettingBehavior
OFFDisplay up to 20 (system default)
ONSpecify maximum between 1-20 (default 5)
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.
PriorityCriteria
1Ads with Targeting settings prioritized
2Ads with smaller Targeting pool prioritized
3Ads with lower Campaign progress prioritized
4CPP ads displayed randomly
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

Close Button Delay Time

High exposure, CTR, and conversion rate are advantages, but displaying too frequently can harm user experience (UX).
