Viral
A tweet that exceeds typical reach by several orders of magnitude, usually driven by reposts and quote-tweets compounding.
In depth
There's no official threshold for "viral" — most creators use 100k+ impressions on a single tweet as the working definition. Genuinely viral tweets clear 1M.
Viral tweets share patterns: a hook that triggers strong emotion (curiosity, surprise, outrage, recognition), a payoff that delivers on the hook, and a structure that's easy to repost without modification.
