DYK is the social-media shorthand for “did you know?” and is almost always used to open a post or caption that’s about to share a fact, statistic or piece of trivia.
It’s a small-business and brand favourite because it sets up a reason to keep reading. “DYK we hand-roll every croissant at 4am?” is a more engaging hook than “We hand-roll our croissants.”
DYK works in captions, on-image text, Stories and TikTok hooks. It’s slightly less common in conversational DMs.
