The 28-Day LinkedIn Launch Campaign That Actually Works

The day I launched FeedSquad, I wrote one LinkedIn post. It got a reasonable spike. Then I disappeared for nine days because I hadn't planned anything else. The launch was visible for about twelve hours and then it was over.

That is the shape of most founder launches on LinkedIn — one announcement, maybe a follow-up, then silence. It's a structural problem, not a content problem. A cold audience given one post about a product they've never heard of cannot do the work a launch needs to do. The fix isn't writing a better announcement. It's building a 28-day campaign around it.

Why 28 Days

Richard van der Blom's 2025 Algorithm Insights Report — the most comprehensive public study of LinkedIn's current ranking, analysing 1.8 million posts — found that accounts posting two to three times a week with varied formats can see up to 120% higher visibility compared to sporadic posters. That gap is the launch tax on silent founders.

Four weeks is also enough runway for each phase of the campaign to do its job: establish the problem, build investment, launch with evidence, and sustain. Shorter, and your launch post has to do everything alone. Longer, and the first posts are stale by the time you announce.

The Four Phases

Sixteen posts, four per week, one job per week:

• Week 1 (Days 1–7): Problem Awareness — make the audience feel the pain
• Week 2 (Days 8–14): Behind the Scenes — build investment in your specific approach
• Week 3 (Days 15–21): Launch Week — announce, explain, prove
• Week 4 (Days 22–28): Sustain — metrics, roadmap, and the honest retro

Four posts a week is not a magic number. It's a ceiling on what a founder can actually maintain while also launching a product. Dropping below three is where the algorithm forgets you. Going above five tends to dilute each post's reach because LinkedIn's current model appears to treat rapid-fire posting as lower-signal.

Week 1 — Problem Awareness (Days 1–7)

Your one job this week: make people nod. No product mentions, no CTA, no hook about "what we've been working on." Establish that a real, specific problem exists and that you understand it better than most.

Day 1 — The Frustration Post. A concrete moment where you personally hit the problem. "Last Tuesday I spent three hours doing X and got nothing." Concrete beats abstract every time.

Day 3 — The Data Post. Back the frustration with numbers. Your own tracking data, a public study, an industry stat. "I tracked how I spent my marketing time for two weeks. 61% went to tasks that generated zero pipeline." Don't cite the number if you didn't actually measure it.

Day 5 — The Observation Post. Point out something broken in the current way people solve this. Take a position. "Everyone tells founders to post consistently. Nobody mentions that consistency without strategy is organised noise."

Day 7 — The Question Post. Ask your network how they handle the problem. Two benefits: comments push reach on this and the next week's posts, and the responses give you language to steal for your launch copy.

Timing. Sprout Social's 2026 timing analysis, based on roughly 2 billion engagements across 307,000 profiles, points at Tuesday through Thursday between roughly 10am and 3pm local time as the strongest window. Monday mornings are cluttered with weekend catch-up; Friday afternoons are over before they start.

Week 2 — Behind the Scenes (Days 8–14)

People now know the problem. This week you build investment in your approach to solving it.

Day 8 — The Origin Story. Not the corporate version. The messy one. "I was watching my launch get zero traction and thought — there has to be a better way." People invest in people, not features.

Day 10 — The Process Post. Show your actual work. A prototype screenshot. A design decision you argued about. A feature you cut. This is the content that separates real builders from people pretending to build.

Day 12 — The Contrarian Take. Challenge something orthodox in your category. "Most tools optimise for volume. We're betting voice accuracy matters more. Here's why." This is also your positioning shaking out in public.

Day 14 — The Teaser. Hint at what's coming with one specific detail — a result, a screenshot, a number — but withhold full context. Curiosity drives saves, and save-weighted signals have become more important in LinkedIn's current model as the team pushes toward "knowledge-worthy" content.

Week 3 — Launch Week (Days 15–21)

This is the week. But you're not starting cold. Two weeks of context mean the network already understands the problem and is primed.

Day 15 — The Announcement. Clear, direct, no fluff. What it is, who it's for, how to get it. Include a visual — screenshot, product image, or under-90-second native video. Lead with the audience's outcome, not your feature list.

Day 17 — The Deep Dive. Pick your most impressive feature. Explain it in one specific example. Not "it's powerful" — "here is what happens when you paste a URL."

Day 19 — The Social Proof Post. Early user reactions. Screenshots of actual DMs work better than quote graphics. The texture of real language is what reads as authentic; a polished testimonial reads as marketing.

Day 21 — The Lessons Post. Something you got wrong during the build. This is usually the highest-engagement post of launch week because it gives value even to people who won't buy.

About link posts: LinkedIn's product leadership has publicly stated that links don't trigger an explicit penalty, but independent studies from van der Blom and others consistently show link posts reach 25–50% fewer people than identical link-free posts. My read: whether the penalty is intentional or emergent, it exists. For launch week, accept the trade and include the link. You want clicks, not just impressions.

Week 4 — Sustain (Days 22–28)

Most founders go silent after launch week. That is the worst possible time to stop. The algorithm has elevated your reach because of the Week 3 engagement spike. Spend it.

Day 22 — The Behind-the-Numbers Post. Real launch metrics. Signups, revenue, conversion, whatever you can share. Transparency outperforms adjectives. "7 days post-launch: here's what happened" posts consistently generate the longest comment threads I see from founders.

Day 24 — The User Story. Spotlight an early user's outcome. With permission. This shifts the narrative from "my product" to "their result."

Day 26 — The Roadmap Post. What's coming. This closes fence-sitters and signals longevity.

Day 28 — The Reflection Post. Honest reflection on the launch experience. What surprised you. What you'd do differently. These posts outperform most launch content because they're the opposite of a pitch, which means the audience rewards them with actual attention.

What the Algorithm Is Doing Underneath

Three things worth knowing because they shape the whole plan:

The first 60–90 minutes after posting decide the post's eventual reach. Early engagement signals — comments especially — tell the algorithm whether to keep pushing. This is why Week 1's question posts matter: they train your immediate network to comment early.

Comments weigh heavier than likes by a wide margin. Posts with substantive comments are 2–3x more likely to reach second- and third-degree connections.

The algorithm evaluates you, not just each post. Consistent posting in a coherent topic builds what LinkedIn editors call "creator reputation" — your future posts start with more reach because the platform has learned what you're about. This is the real compounding asset of the campaign: not a single launch, but the baseline visibility you carry into every launch after it.

Timing Cheat Sheet

Phase	Days	Posts	Strong days	Strong window
Problem	1–7	4	Tue–Thu	~10am–3pm local
Behind the Scenes	8–14	4	Tue–Thu	~10am–3pm local
Launch Week	15–21	4	Mon–Fri (spread)	~8–10am + midday
Sustain	22–28	4	Tue, Thu	~10am–2pm local

These are starting points, not rules. Your audience's pattern may differ. Two things to treat as non-negotiable: do not post after Friday 2pm in any phase, and protect Monday 8–9am — it's the most competitive slot on the platform, so unless your post is your strongest, you'll get buried.

If building sixteen on-voice posts across four weeks is the part that stalls, that is the problem FeedSquad's Ghost agent was built for — it drafts the full campaign from your URL and voice profile, and you edit.

FAQs

When should I start posting about my launch on LinkedIn?

Two weeks before launch day. Your audience needs context before they'll care about your announcement. Starting early means the launch post lands with people who already understand the problem and feel some investment in the solution.

Do I need a large following for this to work?

No. The campaign structure compounds. Each post builds on the previous one, and LinkedIn's algorithm rewards consistent posting. A focused 2,000-person audience engaged with your content will out-produce a 20,000-person audience that hasn't heard from you in months.

What's the best time to post during launch week?

Tuesday through Thursday, late morning to early afternoon in your audience's primary timezone, based on Sprout Social's 2026 aggregate data. Launch day itself can tolerate a slightly earlier slot (8–9am) to maximise the first-90-minute window.
