Why this lesson first: of your three platforms, LinkedIn has the lowest camera barrier — it's text-first. It's the best place to publish your first real piece while the on-camera skills catch up. Master it and you're publishing weeks earlier.
First, recall
Without scrolling: what are the 3 signals every feed reads, in order? (Check the cheat sheet.) We'll now see exactly what each one looks like on LinkedIn.
The format: the text post
LinkedIn's native unit is a short text post — a few hundred words, no video, no face required. (Carousels — "document" PDFs — and native video exist too, but text is where you start.) This is why it fits you today: it's content made of writing about what you already do as a dev.
What LinkedIn rewards — the 3 signals here
Stop = your first 1–2 lines. The feed shows only those before a "…see more" cut. If they don't earn the click, nothing below is read. Hook = your opening line.
Stay = dwell time — how long someone lingers on your post. Short lines, white space, and a story keep them reading. Value + Payoff = the body.
React = comments above all. Comments (especially in the first hour) are the strongest reach signal on LinkedIn, and replying to them compounds it [LinkedIn creator guidelines]. CTA = ask a question.
The one mistake that kills reachExternal links get throttled. LinkedIn wants people to stay on LinkedIn, so a post with a link in the body reaches far fewer people. Put the link in the first comment instead, and say "link in comments." [LinkedIn creator guidelines]
Worked example · a faceless LinkedIn post about a bug
Line 1 (hook): "I lost 3 hours to a bug that was one missing await." ← all most people see before "see more"
Body (value + payoff): short lines — what broke, the wrong assumption, the fix, the lesson. Lots of white space.
Last line (CTA): "What's the dumbest bug that ever cost you hours? 👇"
No camera, no editing — just writing. This is a piece you could publish this week.
Quick self-check
No clues in the formatting — pick from memory, then click.
1. On LinkedIn, the "Stop" signal is won or lost in your…
The feed shows only your opening lines before "…see more". Those lines are your hook — if they don't earn the click, the rest is never read.
2. Which reaction gives a LinkedIn post the strongest reach boost?
Comments — especially in the first hour, and doubly so when you reply — are LinkedIn's loudest reach signal. That's why the best CTA here asks a question.
3. You want to link to your blog. The reach-safe move is to…
LinkedIn throttles posts with external links in the body. Put it in the first comment and write "link in comments" — you keep the reach and still route people out.
