The use of Carousel Ads format was suggested for Wolt's communication strategy by the Wise.Blue team.

Carousel Ads are an engaging format on Twitter that support up to six swipeable, edge-to-edge images or videos in a single Tweet, that all serve as clickable space for a website landing page or app download page of your choice. This added creative space and flexibility allows brands to tell their full story, drive a specific action, and deliver the right message. The visually interactive media is also more appealing than standard single assets, and can help promote engagement.
