In more detail
Stories normally vanish 24 hours after you post them. Highlights, available on Instagram and Facebook, let you group chosen Stories under a custom title with its own cover image, and they sit in a row at the top of your profile permanently. People use them to organize evergreen content that new visitors should see right away: product lines, reviews, FAQs, how-tos, or an "about" intro. Because a highlight is one of the first things someone sees when they land on your profile, it works like a mini menu for your brand.
Example
A coffee shop posts a Story showing its new oat milk latte. After 24 hours that Story would disappear, so they save it to a highlight called "Menu." A week later, someone discovers the profile, taps the "Menu" bubble, and sees the latte plus a dozen other drinks, even though every Story in it has long since expired from the main feed.
