Almost every LinkedIn growth guide is a guide to broadcasting better: fix the headline, sharpen the hook, post on Tuesday at 8 AM, keep paragraphs short. All of it is fine, and all of it optimizes the wrong half of the platform. On LinkedIn, the post is not the distribution engine. The conversation around it is. The accounts that grow treat their own posts as the smaller half of the work and the comment section, theirs and everyone else's, as the larger half.
I am a solo founder who has built software most of my career, and I bootstrapped Sydium from Romania with no audience to lean on. The audience I do have came from X, not LinkedIn, and I built it with a reply-first system: replies were worth far more than likes, and at peak that approach was pulling around 332K impressions a week. The platform is different; the mechanic is not. On any network where a small account starts invisible, distribution is bought in other people's comment sections before it is ever earned in your own feed.
LinkedIn rewards conversation, not publishing
Four things make LinkedIn behave unlike Instagram or TikTok, and every one of them points at the conversation rather than the post.
- Dwell time matters. LinkedIn tracks how long people spend reading. A post that holds attention beats one that gets a fast scroll-by like.
- Comments outweigh likes. A post with 50 real comments travels further than one with 500 likes, because comments are what people stop to read.
- External links get throttled. LinkedIn wants people to stay on LinkedIn, so posts with external links can lose a large chunk of reach versus native posts, according to experiments by Richard van der Blom.
- Your network is the distribution. When a connection engages with your post, it surfaces in their connections' feeds; when you comment on someone else's post, your name and headline ride into their audience. That cascade is LinkedIn's version of virality, and it runs on engagement, not on what you publish.
Read those four together and the strategy inverts. The platform does not reward whoever publishes the most polished thing. It rewards whoever generates conversation. Publishing is how you start one.
Spend more time in other people's comments than in your own posts
This is the move almost nobody makes, and it is the one that works when you are small. When your account is unknown, your own post reaches a sliver of your connections, because the system has not decided you are worth distributing. But a sharp comment, posted early on a post from a bigger account in your niche, gets seen by that account's entire engaged audience. You are borrowing distribution you have not earned, and doing it daily means the right people start recognizing your name before they have ever seen one of your posts.
So invert the ratio. Treat commenting as the main channel and posting as the support act, at least until you have a core that engages. In practice that is a focused block of real comments each day on posts from people one or two tiers above you, posted in the last hour, adding a genuine perspective or a sharp question. Not "great post," but something a reader would stop on. Those comments are tiny posts that appear in feeds you could never reach on your own.
It feels backwards because it is. The payoff compounds later: once you have a small audience that actually replies, your own posts start getting pushed, because the system can see that the people who find you stick around to talk.
Your profile is the page they land on after the comment
Every good comment sends a few people to your profile, and they decide whether to follow in seconds. That makes the profile a conversion page for the conversations you are already having.
Skip the job title in your headline and write what you do and who you help. "Software Engineer at TechCorp" tells a stranger nothing; "Building Sydium, helping creators manage social media without the burnout" tells them whether to stay. Pin your best work to the Featured section most people leave empty, and turn on Creator Mode so your button reads Follow instead of Connect.
None of this grows you on its own. A perfect profile with no conversations driving traffic to it is a beautiful page nobody visits. Fix it once, then go back to the comments.
Posts are the conversation starters, so write the ones people argue with
When you do publish, judge a post by one question: will it produce comments? That filter kills most of the corporate-update genre and rewards a few reliable types.
Personal stories with a professional lesson perform because people respond to a real experience. Open with a hook, tell the story, pull out the insight, and end on a question. The question is not decoration; it is the whole point.
Tactical how-to posts get saved and discussed because they are useful, like "How I write a week of posts in 90 minutes." Contrarian takes do the heaviest lifting, because people either strongly agree or strongly disagree and both camps comment. Behind-the-scenes posts with real numbers earn replies because the feed is starved for honesty.
Format serves the same goal. The first line is everything, since only about 140 characters show before "see more," and short paragraphs keep a phone reader scrolling. But formatting is not the work. The work is having something worth replying to.
I spent $0 on marketing last month.3,200 website visits. 247 signups. 12 paying customers.Here is exactly what we did (no ads, no tricks):1. Posted 4x/week on LinkedIn (you are reading one right now)2. Spent more time in other people's comments than on my own posts3. Turned one blog post into a week of conversation startersCadence and timing only set the table
Here is where most guides oversell precision. Posting on the perfect day at the perfect minute does not grow a small account; showing up in the conversation every day does. Timing only decides who is awake when your starter goes out, so a workable cadence is two posts a week as a floor, three to four as the sweet spot, daily only if you can hold quality. For timing, Buffer's analysis points to Tuesday through Thursday, mornings around 7 to 9 AM and early evening around 5 to 6 PM in your audience's local time. Use it as a default, not a ritual. The point of scheduling ahead is not to hit a magic minute; it is to take publishing off your plate so the energy goes into the comments. Sydium handles LinkedIn scheduling so you can prepare a week at once, freeing the hour that should be going into conversation.
One hard rule follows from all of this: no engagement pods, no automation. The whole strategy depends on real conversation, and fake conversation is the one thing LinkedIn detects and throttles. Automating the comment section is automating away the only lever you have.
Newsletters and video extend the same logic
Two underused features push the conversation past the feed. LinkedIn Newsletters give you direct distribution: every subscriber gets an email and a push notification when you publish, no algorithm in between, so go longer (500 to 1,500 words) on a topic you can only graze in the feed. Video is where LinkedIn is currently spending its reach: a 30-to-90-second clip of one real insight to camera gets pushed harder than text right now, and it draws the kind of comment that keeps a post alive. Both are worth using, but neither matters if you are not in the comments doing the work.
The mistakes that all share one root
The common LinkedIn mistakes are filed as five separate problems. They are one problem in five outfits: treating the platform as a broadcast channel instead of a conversation.
Writing like a corporation ("We are excited to announce...") kills replies, because nobody talks back to a press release. A link in every post buries your reach, so save links for the comments. Humble-bragging invites an eye-roll, not a reply, so be plain: "I got promoted, here is what I learned." Posting only about your company forgets that people follow you for your take, not your product, so keep promotion around 10 to 20 percent. And ignoring comments is the worst of the five: every unanswered comment is a boost you declined. The fix for all of them is the same: stop broadcasting at people and start talking with them.
What growth realistically looks like
Early on, almost nobody answers, which is normal. A few months in, the comments you have been leaving start sending people to your profile, your own posts begin drawing real replies, and some cross a thousand views. Keep going and you become a recognizable name in your niche, with the occasional post breaking 10K and inbound opportunities arriving.
LinkedIn growth feels slower than TikTok at the start and compounds far more reliably, because you are not chasing reach, you are building relationships that keep producing it. An audience of 5,000 engaged LinkedIn followers is often worth more than 50,000 elsewhere, since these are professionals with budgets and hiring authority.

FAQ
Personal profile or company page?
Personal profile. Company pages get a small fraction of the organic reach, because the algorithm favors people over brands and people only have conversations with people. Post from your own account and occasionally reshare to the company page, never the reverse.
How long should a LinkedIn post be?
For text posts, 150 to 300 words: long enough to deliver value, short enough to read in a minute and still leave room to comment. Carousels work best at 8 to 12 slides, newsletters at 500 to 1,500 words.
Can I repurpose content from other platforms?
Yes, but adapt it. A TikTok script can become a text post once you rewrite it for a professional reader. The ideas transfer; the packaging has to change. More in our content repurposing guide.
Do hashtags still matter?
A little. Use three to five relevant ones and treat them as search, not distribution. A post your connections actually talk about beats a hashtagged post nobody comments on.
