|----------------|
| **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](https://www.linkedin.com/help/linkedin/answer/a518996) · [Upload and share documents](https://www.linkedin.com/help/linkedin/answer/a518909)

**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.

## How the Feed Ranks (what to write for)

- The feed is **not** a pure reverse-chronological friend list. It blends **1st-degree connections, follows, company/topic interest, and recommended “out of network”** content from the **Economic Graph**, plus ads. [How the Feed ranks content](https://www.linkedin.com/help/linkedin/answer/a9554004)
- Relevance uses **context** of the post, **profile and network signals**, and **behavior** (read, react, comment, share, **dwell**). Demographics like age or gender are **not** used to rank feed visibility (per public help guidance).
- Platform direction in recent public communications: more **LLM/semantic** understanding, less **inauthentic engagement** and **engagement-bait** / low-quality repetition; favor **real expertise** and **meaningful** discussion. [Background on feed engineering (blog)](https://www.linkedin.com/blog/engineering/feed/engineering-the-next-generation-of-linkedins-feed)

**Writing implications**: Strong **first line** and **on-topic depth**; comments that add substance; avoid templates that look automated or “pod” coordinated.

## Off-Site SEO and GEO (brief)

- **Short feed posts** are often **login-gated** for crawlers; do **not** assume every post is indexed on Google like a blog post.
- **Public profile, Company Page, and Articles** (where public) are stronger for **name/company/role** style queries. Align **headline, about, and entity names** with your site and other public bios for **E-E-A-T**-style consistency.
- **GEO** (AI/search answers): one clear, quotable line **who you help** + links to **evidence** (site, case study, talk) in profile or long-form, not only in DMs or groups.
- For **link previews** on social: **open-graph**; for people/org **entities**: **entity-seo**; for **generative/AI search** strategy: **generative-engine-optimization**.

## Character Limits

| Type | Limit | Notes |
|------|-------|-------|
| **Post** | 3,000 characters | Optimal: 1,300–1,600 |
| **First line (critical)** | 210–235 chars | Visible before "See more"; 60–80% decide here |
| **Short posts** | 100–200 chars | Polls, announcements, quotes |

## Optimal Length by Content Type

| Type | Characters | Use |
|------|------------|-----|
| **Short** | 100–200 | Polls, announcements, quotes |
| **Medium** | 300–1,200 | Case studies, tips, BTS |
| **Long** | 1,200–2,000 | Thought leadership, analysis |
| **Sweet spot** | 1,300–1,600 | Highest engagement |
| **Avoid** | >2,000 | ~35% engagement drop |

## First Line (Hook)

- **Place key message in first 140 chars**
- **Strong openings**: Specific results, pain points, bold claims, surprising stats
- **Avoid**: Vague teases, hashtag-first, generic greetings

## Image Specs (for Design Agents)

| Format | Dimensions | Use |
|--------|------------|-----|
| **Single image** | 1200×627 (1.91:1) | Feed; link previews |
| **Square** | 1200×1200 | Single image |
| **Carousel (organic)** | Up to 20 images | Multi-image post |
| **File** | ≤10 MB; JPG/PNG | Native uploads perform better |
| **Vertical** | Preferred | 88% browse on mobile |

## Best Practices

- **Mobile-first**: 88% users on mobile
- **Polls and document (PDF) posts**: Often strong for reach; pair with a clear takeaway
- **Post frequency**: Weekly minimum is a common bar for company pages; individuals often **several times per week** if sustainable
- **Alt text**: Add for accessibility
- **B2B tone**: Professional and constructive; see **influencer-marketing** and **about-page-generator** for voice alignment with profile/brand

## Output Format

When generating LinkedIn copy, provide:

1. **First line** (≤210 chars; hook)
2. **Full post** with character count
3. **Hashtags** (a few, relevant; end of post)
4. **Image specs** (if design agent needs dimensions)
5. **Form note** if not a plain post (e.g. “pair with a 5-slide document” or “use Article for 1,200+ words”)
