Training Claude on Your Best LinkedIn Posts

Core idea: "You can train Claude on your (best) LinkedIn posts." Export your post history, have Claude analyse what actually performs, then bake those findings into a reusable Claude skill that drafts new posts in your proven style.

The Full Process

Step 1 — Extract LinkedIn posts (~$2–5)

Use Apify to pull public posts (no automation on your own account — respects LinkedIn ToS):

  1. Free account at Apify console — gives ~$5 free credit.
  2. Open the LinkedIn posts actor.
  3. Paste a LinkedIn profile URL with the recommended settings.
  4. Wait 2–10 min for the run.
  5. Export as spreadsheet (CSV / XLSX).

Capture includes: post content, engagement metrics, media URLs, and timestamps (encoded in the activity IDs).

Step 2 — Analyse with Claude

Feed the export to Claude with an analysis prompt ("Treat this as a serious analytics deliverable"). It should:

  • Calculate engagement (likes + comments + shares).
  • Identify post format (text, image, video, carousel, article).
  • Analyse angle / hook patterns.
  • Flag outlier performers.
  • Produce Stop / Continue / Start recommendations.
  • Output two deliverables: a written report and an SOP.

Key instruction: "For visual posts don't judge from the caption alone: actually OPEN THE MEDIA and look at it."

Step 3 — Turn it into a reusable Claude skill

In the same chat:

/skill-creator — "Create a skill combining what matters inside the content report… Call the skill [your-name]-viral."

The skill should: embed the report insights, ask clarifying questions first (AskUserQuestion), then generate multiple angle/hook variations with captions + media guidance. Save it so it's reusable across new chats.

Step 4 (optional) — Extract an ultra-viral "recipe"

For a standout post: screenshot it, then

/skill-creator — "This post went extremely viral… capture the recipe."

Claude extracts format, hook (first lines), caption structure, and tone into a skill you can apply to new content.

Limitations (author's own caveats)

  • "AI isn't creative… it's really good at following instructions." Best for iteration, not pure novelty.
  • Needs a real cadence (≥ ~weekly) and works best with 30+ quality posts.
  • "It does not work if you're bad at LinkedIn."
  • Claude subscription ~$100/mo.

Example result: from 489 analysed posts, Claude generated 5 post options, each with caption copy + image direction consistent with historical top performers.
