The cover is the landing, or first page of your Web Story. If a user lands on your cover that means your poster image caught their attention, congratulations! The next step is keeping them engaged.
In many cases, a poster image and cover page will look similar. However, the cover page has much fewer restrictions than the poster image. Instead of one static image, you now have full use of video, audio and animations. While you can change your cover page completely from the poster image, it’s best to ensure that users feel like the story they tapped or clicked into matches the poster.
