Integrate fly-in ads onto your website and flexibly control their position, behaviour and appearance via numerous configuration options.

Overview
With Fly-In Ads, you can display advertisements as a subtle overlay on your website. Unlike traditional ads, Fly-In Ads are not displayed directly at the position of the integration code, but slide in at the edge of the browser window depending on your settings.
Fly-In Ads are particularly suitable for attracting attention without interrupting the users' reading flow.
Requirements
Before you can use Fly-In Ads, you need:
a created website in your publisher account
an ad block
a matching ad block layout
a working responsive or static ad block
Fly-In Ads can be used with both Responsive Ads and Static Ads.
Activate Fly-In Ads
Fly-In Ads are activated via the optional parameter flyin.
Asynchronous Integration
flyin: true
Synchronous Integration
flyin=1
As soon as this parameter is set, the ad is displayed as a fly-in overlay.
Behaviour of the Fly-In Container
flyin_mode
With flyin_mode, you control when and how the fly-in container becomes visible.
Mode 1 (Standard)
The container reacts to the scroll position.
Scroll position | Behaviour |
|---|---|
0–20% | not visible |
20–40% | half open |
from 40% | fully open |
flyin_mode: 1
Mode 2
The ad is fully visible immediately after the page loads.
flyin_mode: 2
Mode 3
The ad only appears when the end of the page has been reached.
flyin_mode: 3
Set Position
flyin_position
Determines which side the fly-in container fades in from.
Available values:
right(standard)lefttopbottom
Example:
flyin_position: "top"
Define Offsets
The position of the fly-in container can be adjusted via pixel values.
Parameter | Description |
|---|---|
| Offset to the top |
| Offset to the right |
| Offset to the bottom |
| Offset to the left |
By default, each offset is 15 pixels.
Example:
flyin_offset_right: 20
Set Delay
flyin_delay
Determines the time after which the fly-in container is first displayed.
The value is specified in milliseconds.
Standard:
250
Example:
flyin_delay: 1000
Control Animation
flyin_animate
Activates or deactivates the folding and unfolding animation.
By default, animations are enabled.
Example:
flyin_animate: false
Allow Closing
flyin_closeable
Determines whether users can close the fly-in container.
Standard:
flyin_closeable: true
Deactivate:
flyin_closeable: false
Allow Folding and Unfolding
flyin_collapsible
Controls whether the user can fold or unfold the container.
Example:
flyin_collapsible: false

Best Practices
Use Fly-In Ads subtly
Fly-In ads achieve the best results when they assist users and do not distract from the actual page content.
Delay display
A short delay ensures that visitors can first perceive the actual content.
Recommendation:
500–1000 ms
Allow closing
Keep the close button activated so users can hide the ad at any time.
This improves the user experience.
Test mobile display
Check Fly-In Ads on:
Desktop
Tablet
Smartphone
Pay particular attention to ensuring that no important content is obscured.
Common Sources of Errors
Fly-In not activated
All other Fly-In parameters are only considered if flyin has been activated.
Too large offsets
Very large offset values can cause the container to be partially outside the visible area.
Too early display
A fly-in directly when loading the page can be perceived as disruptive.
Instead, use flyin_delay or the scroll-based mode.
Animation deactivated
If animations are deactivated, the container appears without a transition. Depending on the design, this can look less harmonious.
Typical Application Areas
Fly-In Ads are particularly suitable for:
Product recommendations
Native Advertising
Content recommendations
Newsletter sign-ups
Cross-selling
seasonal campaigns
