How to Write a Post People Actually Read
The first sentence decides whether anyone reads the second. Open with background — "Today I want to share something that happened to me recently" — and you’ve already lost half your readers before you even reach the actual point. People don’t decide to read you because of a clever headline or a polished layout. They decide in a fraction of a second, mid-scroll, whether the first words they see are worth stopping for. Everything else in the post, no matter how good, only matters if that first moment is won. So writing a good post doesn’t start with what you want to say — it starts with what will make someone stop scrolling and read you specifically.
The first-sentence rule
The first sentence isn’t allowed to be "context." It needs to carry the actual idea, a specific fact, or a line that physically stops the scroll — the reader’s thumb pausing mid-motion. Context can come after, if it’s needed at all, and often it isn’t needed because people understand the situation from the claim itself. Compare "Last week I made a mistake that cost me a client" with "I want to tell you about something I learned last week about business." The first is specific and creates curiosity immediately. The second is a polite introduction that gives the reader no reason to keep going. The difference between the two isn’t the quality of the story underneath — it can be exactly the same story — it’s only which sentence comes first.
One idea per post
If a post tries to say three things at once, the reader remembers none of them. Pick one thought, ruthlessly cut everything that doesn’t directly serve it, and save the rest for a separate post later. This is hard in practice, because when you’re writing about a topic you know well, the temptation is to add every nuance, every exception, every extra thought that occurs to you in the moment. The result is a post that technically contains more information but practically communicates less, because the reader can’t extract one clear message from it. If you can’t summarize your draft in a single sentence after writing it, that’s a sign you’re actually writing two or three posts merged into one.
Structure: claim, evidence, takeaway
State what you think, directly, without hedging. Then show why with a specific example, a moment from your own experience, or an observation the reader can easily picture. Close with a takeaway, a short piece of advice, or a question that invites a reaction, instead of just stopping abruptly. This structure works because it’s easy to read even on a phone, one-handed, mid-scroll, standing in line, or waiting for something else. It doesn’t ask the reader to hold a complex argument in their head — each step is clear on its own, and the logic connecting them is direct enough to follow even on a quick, distracted read.
Length depends on the platform
LinkedIn tolerates longer text if every sentence carries real value with no filler — that audience reads with intent to learn something and is willing to spend more time. Instagram and X punish long openings because the visual context is different there — the first two lines have to do all the work before "see more" hides the rest. Short-form platforms demand compression up front, not at the end: don’t save your best detail for the closing line, because most of the audience will never get there. It’s better to lose a detail than to lose the reader in line one, before they even understand why it’s worth continuing. If you’re unsure how long to write, picture someone reading one-handed on their phone while standing — if the text demands more attention than that posture allows, it’s probably too long for the platform you’re posting on.
How to check if your post actually works
Read the first sentence out loud, separate from the rest of the text, and ask yourself honestly: would I stop scrolling if this were all I saw, knowing nothing else about the topic. If the answer is "probably not," rework it before touching anything else in the post. Another quick test is to show only the first sentence to someone unfamiliar with the topic and see if they instinctively ask "and then what happened." If it provokes a question, it works. If it only gets a polite nod, go back and find a sharper angle or a more specific detail to open with. This test is worth more than waiting to see live reactions, because it gives you feedback immediately, before the post ever reaches a real audience.
A common mistake: explaining before the point
The most common mistake in writing posts isn’t a bad idea, it’s the wrong order of presenting it. Most people instinctively want to explain the situation first, then the context, and only then arrive at the actual thought that’s interesting. The problem is that most of the audience never reaches the end of that explanation. The fix is simple, if counterintuitive: reverse the order. Say the most interesting thing first, then add the context that supports it, if needed at all. Readers who are genuinely interested will read the explanation too — but only because the first sentence already won them over.
The closing line carries as much weight as the opening
A lot of attention goes into the first sentence, but the last one deserves care too, because it decides whether the reader comments, shares, or simply moves on in silence. A closing like "That’s what I learned" feels safe but invites nobody to respond. It works better to end with a specific question that requires a personal answer rather than a general opinion — not "Do you agree?" but "Has something like this happened to you with a client?" A specific question is easier to answer, because the reader doesn’t need to form a philosophical position, just share their own experience, which lowers the barrier to leaving a comment considerably.
