You can start by using longer videos or multiple images. Also, try adding text and stickers to make it more engaging and keep people's attention for longer.
The key to making your Instagram story last longer is to be creative and strategic. For example, you could tell a story in parts over multiple stories to keep people coming back for more. Also, using music or sound effects can enhance the experience and make it more memorable, which might make people watch for a longer time.
Well, to make your IG story last longer, one way is to plan out your content in advance. Think about what you want to show and how you can present it in an interesting way. Another tip is to use the full 15 seconds for each clip if it's a video story. And don't forget to use relevant hashtags to increase its visibility.
