What is a characteristic of a Sidekick ad?

A Sidekick ad is known for its interactive and expandable nature. When activated, it expands to a canvas size that can reach up to 970x550 pixels. This feature allows for more engaging content and offers advertisers the ability to present richer media experiences compared to standard display ads. The expandable format can attract more viewer attention, as it provides additional space for creative elements, such as videos, animations, and interactive components, which can enhance user engagement and interaction with the brand.

The other characteristics refer to different types of ad formats or limitations not associated with Sidekick ads. For example, fixed dimensions, which limit creative flexibility, are not applicable to the Sidekick format, as its primary strength lies in its expandability and interactivity. Therefore, the emphasis on expandable capabilities highlights why the choice pointing to a maximum canvas size aligns with the true characteristics of a Sidekick ad.
