What are LinkedIn Posts?

LinkedIn posts are short-to-medium form updates published from a personal profile or company page. They can include text only, single images, carousel-style documents, native video, or link previews. Compared to other networks, LinkedIn is text-forward: posts can run up to 3,000 characters, and pure-text posts often outperform image posts on the platform. The audience is professional — 875 million LinkedIn members, with 200+ million in the United States alone — and roughly 4 of 5 LinkedIn members drive business decisions.

For US small businesses, consultants, and B2B founders, LinkedIn posts are the single highest-ROI organic channel. A well-targeted LinkedIn post can produce inbound demo requests within hours — something that almost never happens on Instagram or TikTok. The platform rewards long-form storytelling, expertise demonstrations, and personal narrative. The downside is the writing load: a strong LinkedIn post requires a real hook, a real story, and a real takeaway, every single time. AI writing assistance closes the gap between "I know what I want to say" and a polished, posted update.

How to create LinkedIn Posts with publy.ch

With publy.ch you go from idea to scheduled LinkedIn post in under five minutes:

  1. Set up your brand voice — publy.ch learns your tone from samples or your website, so generated text sounds like you, not generic LinkedIn.
  2. Choose a post type — narrative story, listicle, contrarian hot-take, case study, or thought-leadership essay.
  3. Generate the hook + body — the AI writes a 3-line hook (the part visible before "see more") plus a structured body with line breaks tuned for mobile.
  4. Add a branded visual — for image posts, generate an on-brand square or portrait graphic with your headline and logo.
  5. Schedule for peak hours — Tuesday through Thursday, 8–10 a.m. or 12 p.m. ET, perform best for US business audiences.

The whole workflow respects how LinkedIn actually rewards content: hook first, value-dense body, single clear CTA.

Best Practices for LinkedIn Posts

  1. Nail the first 210 characters. That is what shows before LinkedIn collapses the post with a "see more." If the hook doesn't land, nothing else matters.
  2. Use line breaks aggressively. Single-line paragraphs feel native on LinkedIn. Walls of text get skipped.
  3. Pick one CTA per post. "Comment your take," "DM me for the template," or "Save this." Don't stack CTAs.
  4. Avoid external links in the post body. LinkedIn de-prioritizes posts that send users off-platform. Put links in the first comment instead.
  5. Engage in the first 60 minutes. Reply to every comment within an hour of posting. The algorithm reads engagement velocity as a quality signal.
  6. Mix formats. Rotate text-only, single-image, document carousel, and native video across the week. Pure-text-only feeds stagnate.
  7. Hashtags: 3 to 5 relevant tags. No more. LinkedIn isn't Instagram — keyword stuffing hurts.
  8. Post consistently 3–5 times per week. LinkedIn's algorithm strongly rewards consistent posters, more than any other network.

Formats and Dimensions

  • Text-only posts: up to 3,000 characters
  • Single image: 1200 × 1200 px (square) or 1200 × 1500 px (portrait) recommended
  • Native video: up to 10 minutes; 1920 × 1080 (landscape) or 1080 × 1920 (vertical)
  • Document / carousel: PDF, up to 300 pages; 1080 × 1350 portrait recommended
  • Link preview image: 1200 × 627 px (1.91:1)
  • File formats: JPG, PNG, MP4, PDF

Common Mistakes to Avoid

  • Cross-posting from Twitter or Instagram. LinkedIn's tone is professional but human; copy-pasted Tweets feel out of place.
  • Treating LinkedIn like a resume. "I'm pleased to announce" posts get ignored. Tell a story instead.
  • Posting and ghosting. Failing to reply to comments tanks reach. The first hour is critical.
  • External links in the body. They suppress reach. Put links in the first comment.
  • Inconsistent posting cadence. Once a month doesn't compound. 3–5x per week builds an audience.
