Module 1: Dwell Time
The number-one ranking signal, dissected: how the algorithm actually measures attention, the mechanics that generate it — the 'see more' click, carousel swipes, video watch time — and how to engineer every post to earn seconds instead of glances.
How the algorithm measures attention
LinkedIn can see exactly how long your post sits on someone's screen — not whether they liked it, but how many seconds they spent with it open. This is dwell time, and it sits at the top of the signal hierarchy for one reason: it measures the thing the platform actually sells, which is attention. A like takes half a second and costs nothing. Forty seconds of someone's actual focus cannot be faked at scale.
The mechanics matter. The single most valuable micro-action on LinkedIn is the ...see more click — when a reader expands your post, the algorithm logs deliberate intent to keep reading, and the dwell clock runs while they read the full text. This is why the first two lines are everything: they are not the post, they are the advertisement for the click. Carousel swipes work the same way — each swipe is a logged micro-commitment, and ten slow swipes can generate more measured dwell than any text post. For video, it is watch time and completion: a viewer who watches 45 seconds of a 60-second video sends a far stronger signal than one who watches 5 seconds of a 30-second clip.
This reframes the entire game. You are not writing for likes or even for comments — you are writing for seconds. Every formatting choice, every line break, every word exists to do one thing: keep the reader's eyes on your post for ten more seconds. Likes are applause. Dwell time is the algorithm's vote — and it counts the seconds.

Take your best-performing LinkedIn post ever. Rewrite just its first two lines three different ways — a surprising claim, a curiosity gap, and a named pain. Which version would earn YOUR 'see more' click?

The first two lines decide everything
LinkedIn shows roughly two lines of your post before the ...see more cut. Everything below that line is invisible until someone clicks. Your entire post lives or dies on those two lines — they are the only part guaranteed to be seen, and they are the trigger for the single most valuable dwell action: the expansion click.
The best openers do one of three things. A surprising claim that contradicts what the reader believes ('I lost 200 followers by posting more'). A curiosity gap that opens a loop the reader needs closed ('The best LinkedIn advice I ever got came from a plumber'). Or a named pain so specific the reader feels seen ('Your posts get 300 views because of line three'). What they never do: warm up. No 'Excited to share,' no 'Quick thought,' no throat-clearing — every wasted word above the cut is dwell time you will never get back.
Write your first two lines last. Draft the whole post, find the single most interesting sentence in it, and move that sentence to the top. Then cut everything above it. Read the result as a stranger with a hundred other posts competing for the next ten seconds of your life. If your post started with the third paragraph, delete the first two.

Format for the pause — and the click
Once someone stops, your formatting decides whether they stay — and whether they click 'see more.' The LinkedIn feed punishes walls of text: a dense paragraph looks like work, and scrollers do not do work. The fix is whitespace — one idea per line, short paragraphs, line breaks between every thought. White space is not empty. It is breathing room that keeps eyes moving down toward the cut, and then past it.
Structure every post the same way: hook (lines 1–2, engineered for the click), context (lines 3–6, one idea per line, rewarding the click immediately — never make a reader regret expanding), the meat (the insight, story, or lesson in short bursts), and the landing (a final line that resolves or provokes). The critical detail: the payoff for clicking must arrive fast. If lines 3–5 are filler, the reader learns that your 'see more' is not worth clicking — and they will not click next time either.
Two more levers. Numbered structure ('here are 4 things') tells the reader exactly how much attention this costs — a promised finish line keeps eyes moving. And end mid-thought often: a line that clearly continues below the cut ('But the third one changed everything —') is a mechanical click trigger. Use it honestly — the content below must deliver — and it becomes a dwell engine. Make reading feel easy and make the click feel rewarding, and people will read to the end.

Draft a post about something you learned this month. Apply the Dwell Test twice: would a stranger stop for ten seconds, and would they click 'see more'? Rewrite until both answers are yes.

Daniel's posts get plenty of likes but almost no comments, and his reach is flat. His posts are single dense paragraphs with the link in the body and weak openers. What's the highest-leverage fix?
Your turn: Write a full LinkedIn post draft (150–250 words). Then run the double Dwell Test: read only the first two lines as a stranger — would you stop, and would you click 'see more'? Rewrite the opening until both are yes.

Take your next LinkedIn post idea and write three different two-line openers: surprising claim, curiosity gap, named pain. Pick the one that would earn YOUR click, then build the post under it.

THE DWELL TEST CARD
Read your draft as a stranger. Answer honestly:
1. Would I stop scrolling for 10 full seconds? ☐
2. Would I click 'see more' — do lines 1–2 earn it? ☐
3. Do lines 3–5 reward the click immediately? ☐
4. Is there white space between every thought? ☐
5. Is the link in the first comment, not the body? ☐
6. Does it end with a reason to keep thinking? ☐
Any 'no' = rewrite before posting.
Module 1 cheat sheet: Dwell time mechanics
- Dwell time — measured seconds on screen — is the algorithm's strongest signal.
- The 'see more' click is the most valuable micro-action: it logs deliberate intent to keep reading.
- Carousel swipes are micro-commitments; ten slow swipes can out-dwell any text post.
- Video signal is completion rate, not views — 45 of 60 seconds beats 5 of 30.
- The Dwell Test (double): would a stranger stop for ten seconds AND click 'see more'?
- Lines 3–5 must reward the click instantly, or readers learn your expansions aren't worth it.
