Why is responsive design important?

Advertising media is displayed on different devices (smartphones, tablets, desktop). Without adaptation, important content may be cut off or difficult to read.

Responsive implementation ensures that the display is automatically optimized depending on the screen size.

What happens without responsive design?

Static templates are problematic:

On larger screens (e.g. iPad Pro), there are often large white borders that make the advertising material less noticeable.
Text or logos may be cut off on smaller screens (e.g. iPhone X).

How should this be done correctly?

All the elements of an advertising medium must be able to adapt flexibly in terms of size and position.
Fonts, images and call-to-actions (CTAs) should be placed in such a way that they are easy to read and click on any end device.
Use of short, concise texts as well as high contrast and easily legible font sizes.
This is particularly important: Test advertising material on various devices in advance.
