How to Write LinkedIn Posts That Convert for Founders

One idea per post, stated in the first two lines

LinkedIn truncates everything below roughly 210 characters behind a fold. Readers decide whether to click "see more" based on those first lines alone, so the single most important editing decision is what travels to the top. Vague openers such as "I've been thinking a lot about security lately" waste the fold. Specific claims earn the click.

Compare these two hooks aimed at the same audience of IT directors:

1. "Cyber insurance is harder to get this year and here's what that means for your renewal."
2. "As a founder, I consider growth a core operational discipline."

The first names the reader, names a concrete pressure point and promises a payoff. The second is a statement with no stake and no audience. Write the hook last if it helps: draft the body, then compress its core claim into a sentence that names a person and a problem.

After the hook, defend one claim only. Multi-topic posts read like newsletters and get read like newsletters: partially and nowhere. A single strong idea, argued in four to eight short paragraphs, converts far better than a listicle covering five themes at surface depth.

Put proof in the middle, and a next step at the end

Claims without evidence read as marketing. Evidence without claims reads as noise. Useful posts pair them: state the position, then show one piece of support from your actual work. For a boutique dev shop, support looks like an anonymised pattern: "Three of the last four Retrofit migrations we inherited failed for the same environmental-configuration reason, and here's the checklist we now run first."

You do not need named clients, revenue figures or screenshots. What you need is the sense that the claim was earned in the field. Specific detail (the version, the timeline, the failure mode) performs that job better than superlatives ever could.

The ending should offer a next step, and the mistake founders make is making that step transactional. "DM me for my calendar link" on every post reads like a sales engine running cold. Better endings:

• Ask a genuine question that invites practitioners to describe their situation.
• Promise the follow-up: "I'll post the full checklist tomorrow."
• Offer something on request without a pitch: "Happy to share the template if anyone wants it."

Soft steps keep the post readable and still give warm prospects a reason to act. The hard ask belongs in the DM, where you have context, and in your featured section, where the profile does the selling.

Format for skim, then publish when your audience is online

Formatting changes how deeply people read. Short paragraphs of one to three lines, generous line breaks and occasional bullet lists make a post scannable. Long unbroken paragraphs lose readers regardless of how good the idea is. Keep total length between 150 and 300 words for frequent posts; reserve 400 to 700 words for deep pieces you publish weekly.

Timing matters more than most advice suggests. Posting when your buyers are online (typically weekday mornings in their timezone) puts your post in front of them while it still has fresh engagement momentum. A founder targeting UK mid-market firms posting at 9pm IST will underperform the same post published at 8am GMT.

Consistency beats virality. Twenty competent posts over a month build a recognisable voice and steady inbound DMs. One post that hits the viral lottery rarely produces clients because the audience it attracts is not your ICP. Plan around the median, and let the occasional breakout be a bonus.

If writing daily founder content on top of running your firm is unrealistic (and for most founders it is), that is exactly the gap we close. Explore done-for-you LinkedIn ghostwriting at Wes Marketing Solutions or book a 15-minute call.
