Technical specification of ad formats


It is an attractive and progressive format that is reminiscent of popular "stories" on social networks. Pictures and video spots can alternate in short sequences. The user can scroll or skip between creatives. This format cannot be overlooked on the home page or in the article.



In total, a creative can consist of 2-5 slides. Still images or videos can be inserted into individual slides. But beware: the video can be inserted into a maximum of three slides. So The Story can consist of 2-5 pictures or 1-3 videos. You can add still images to the video so that the total number does not exceed 5 slides. Each slide is visible for 5 seconds and then the next one is displayed.
