How to Write LinkedIn Posts with AI

LinkedIn is the highest-signal professional publishing platform available today. Consistent, high-quality posts build your authority, grow your network, and generate inbound opportunity. The problem: most professionals don't have time to write well, consistently.

This guide shows you how to use Bloomberry to produce LinkedIn posts that sound like you — not like ChatGPT — and publish them consistently.

What makes a good LinkedIn post

Before you write with AI, you need to understand what you're optimizing for. A high-performing LinkedIn post has:

• A strong first line — LinkedIn truncates to ~210 characters before the "see more" cutoff. Your first line must compel a click.
• A clear point of view — Not information, but a perspective. What do you believe that others don't?
• Concrete specificity — Numbers, names, examples. "I grew to $2M ARR" not "I grew significantly."
• A natural voice — If it sounds like every other post, it won't perform. Your unique lens is the asset.
• A clear close — Either a takeaway, a question for comments, or a CTA.

Step-by-step with Bloomberry

Step 1 — Write your concept

Open the Writer. In the text area, write your raw concept. Don't polish it — just write what you want to say.

Step 2 — Select LinkedIn format

Below the text area, select the LinkedIn chip. You can also select X or Blog at the same time to produce multiple formats in one generation.

Step 3 — Choose your writing style

• Natural — Works best for personal stories, founder observations, lessons learned
• Punchy — Works best for hot takes, controversial opinions, short-form hooks
• Polished — Works best for thought leadership pieces, industry insights, formal announcements

Step 4 — Generate and review

Click Generate. Bloomberry produces a full LinkedIn post (200–400 words) in your trained voice. Review the post looking for:

• Does the first line make you want to read more?
• Is the main point clear?
• Does it sound like you?
• Is there at least one specific detail?

Step 5 — Refine with chat

Use the chat box below the output to refine:

• "Make the hook more direct — start with the lesson, not the story"
• "Shorter — cut to 200 words"
• "Add a specific number in the second paragraph"
• "Less formal in the last line"

Step 6 — Schedule or publish

Click Schedule to pick a date/time, or Publish now to post immediately to your connected LinkedIn account.

LinkedIn-specific best practices

• Optimal length: 150–300 words for most post types. Longer works for stories and how-to posts.
• Line breaks: Short paragraphs (1–3 sentences). LinkedIn's feed rewards scannability.
• First line rule: Don't start with "I". Start with the insight, the number, or the scenario.
• Hashtags: 3–5 relevant hashtags maximum. Place at the end.
• Post frequency: 3–5x per week is optimal for LinkedIn algorithm.
• Engagement window: Respond to comments in the first hour for maximum reach.
