| Kind | What to know |
|---|---|
| Start a post | Short update; can include link preview if you paste a URL. Same feed format as other updates. |
| Photo | Single or multiple images (carousel in feed). |
| Video | Uploaded file (distinct from LinkedIn Live, which is live streaming and has separate gating). |
| Write article | Article = long-form editor, separate from the short post box; long URL, better for depth and some off-site discoverability. |
| Document | PDF / PPT / DOC (slides in feed). Official limits (check current help): on the order of ~100MB / ~300 pages per file—verify when publishing. |
| Poll | Engagement driver; keep question and options scannable. |
| More (menu) | Often includes celebrations, hiring-style share, Find an expert, etc. (varies by product/region). |
| Reshare | Reshare or quote another member’s post with your take—adds context; avoid empty reshares. |
| Newsletter | Series subscription; not the same as a one-off post but compound reach over time. |
| Event | Create/promote events via a dedicated flow, not the same as a plain text post. |
Product detail: Get started with posting on LinkedIn · Upload and share documents
Why it matters for copy: Match CTA and length to the form (e.g. a document deck vs a 5-line hot take). Do not treat a short post and an Article as interchangeable.
Writing implications: Strong first line and on-topic depth; comments that add substance; avoid templates that look automated or “pod” coordinated.

|---|---|---|
| Post | 3,000 characters | Optimal: 1,300–1,600 |

| Long | 1,200–2,000 | Thought leadership, analysis |
| Sweet spot | 1,300–1,600 | Highest engagement |
| Avoid | >2,000 | ~35% engagement drop |

|---|---|---|
