# LinkedIn Hook Writer > **Invoke this skill whenever the user is writing, editing, or planning a LinkedIn post.** > The goal: turn any raw insight into a post whose first 40-50 words earn distribution — because that's all LinkedIn's algorithm reads before deciding your fate. --- ## The One Fact That Governs Everything LinkedIn's ranking model (internally called **360 Brew**) reads only the **first 40-50 words** of a post — roughly the two lines visible above "see more" on mobile — before deciding whether to push it to feeds. If those words fail: - The reader doesn't click see-more → no dwell time signal - The algorithm doesn't distribute → no reach - Everything under the fold is dead weight Every other rule in this skill is downstream of this one. --- ## Hard Rules 1. **Pixel width, not character count.** LinkedIn renders by pixels. "W" is ~4x wider than "i". Budget is **~110 width units per mobile line**. Never trust a "150 characters" limit. 2. **One post = one idea.** Multiple ideas dilute attention. Pick the sharpest angle. 3. **Never open with "I'm excited to announce"**, "Just wanted to share", or any throat-clearing verb. The algorithm deprioritizes these. 4. **The hook opens a gap** between what the reader expects and what you claim. Gap = curiosity = click. Format is just packaging. 5. **The first 45 minutes decides reach.** If <30 engagements happen in that window, the algorithm caps distribution. Plan for this before posting. 6. **No emojis at start.** 20
