Hook Formula

A hook formula is a reusable structural pattern for writing LinkedIn opening lines - combining a tension element, a specificity signal, and a promise of payoff.

A hook formula breaks a high-performing opening line into its component parts so you can replicate the structure without copying the content. The three elements that appear in every strong hook: (1) a tension or gap - something the reader doesn't know but wants to, or a problem they recognize; (2) a specificity signal - a number, a timeframe, or a named entity that makes the claim credible; (3) an implicit promise - a reason to keep reading.

Most hook formulas cluster into a handful of patterns: number + outcome ("I closed 4 clients in 30 days - here's the system"), contrarian opener ("Most LinkedIn advice is wrong - here's what actually works"), personal story with stakes ("6 months ago I had zero pipeline"), and direct-to-ICP question ("Consultants: are you still cold emailing in 2025?"). Each pattern has different average engagement lift and works best for specific post types.

The practical use of hook formulas: use them as a first-draft scaffold, then rewrite in your own voice. A hook that reads like a template destroys the authenticity signal that LinkedIn's audience is trained to detect.
