Disappearing stories refer to content that is only accessible for a brief period of time before being deleted from the internet. Examples include posts on Snapchat and Instagram stories. While 64% of marketers currently use or intend to use disappearing stories on Instagram, there are both benefits like increased reach and engagement, as well as disadvantages like a lack of consistency if not used as part of a long-term social media strategy. Benefits include wider audiences, more content volume, and boosted loyalty, while disadvantages include decisions without planning and not establishing a company presence first.
