Output: Publish-Ready Copy

This skill enables agents to generate LinkedIn post copy optimized for engagement. Output includes character-counted text and structure for the "See more" threshold.

Post Types and Entry Points (organic)

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.

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.

Platform Positioning

LinkedIn is a professional network—its core value is career identity, B2B relationships, and professional content. Key differences from general social platforms:

Dimension	LinkedIn	Meta / X / TikTok
Primary intent	Job seeking, B2B networking, industry learning	Entertainment, social, discovery
Identity	Real name + career history	Username or lifestyle persona
Content tone	Professional, constructive	Casual, entertaining, opinion
B2B lead value	High (job title + company targeting)	Low to medium
Algorithm signal	Professional interest + network + editorial	Engagement, watch time, virality

Prioritize LinkedIn when: targeting B2B buyers, building professional authority, recruiting, or publishing industry thought leadership. For consumer brand awareness or entertainment, other platforms are often more effective.

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
• 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)

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

Off-Site Search Visibility (SEO & GEO)

LinkedIn content is visible to search engines on a selective basis—understand what gets indexed for SEO and cited for GEO.

What Google Indexes vs. What Is Login-Gated

Surface	Search Visibility	GEO (AI citation) Value
Public profile (Headline, About, Experience)	Indexed for name/company/role queries	Strong entity signal; citable paragraphs
Articles (long-form editor)	Indexed when set to public	High; structured paragraphs with keywords
Company Page	Indexed for brand queries	Medium; brand entity signals
Short feed posts	Login-gated—not indexed	Low; cannot be cited if behind login
Newsletter issues	Indexed if public; behind login if subscriber-only	Depends on visibility setting

SEO Through LinkedIn

• Headline is the most SEO-visible field on your profile—treat it as a title tag. Include primary keyword + value proposition (e.g. “B2B SaaS Marketing | Helping startups scale through content”).
• About section: Write public-facing paragraphs with keywords and proof points. This is indexed and often appears in Google search snippets.
• Featured section: Use to showcase key links (site, case studies, press). These appear on your public profile and add backlink value.
• Articles: Long-form content on LinkedIn ranks independently on Google. Treat as secondary publication, not primary—repurpose site content with canonical or unique article.
• Consistency: Align name, headline, and entity names across LinkedIn, your site, and other public bios. See entity-seo for sameAs alignment.

GEO Through LinkedIn

• Entity consistency: Your LinkedIn profile is a high-authority entity source. AI search tools (ChatGPT, Perplexity, Google AI Overviews) can cite your LinkedIn profile when answering “who is [person]” or “what does [company] do” queries.
• Citable paragraphs: Write your About section in answer-first format (40–60 words per block) so AI tools can extract and cite it directly.
• Evidence links: Add links to your site, case studies, talks, and publications in Featured and About. AI tools cite external links as supporting references.
• Public articles: Publish LinkedIn Articles on relevant topics; well-structured articles with data and citations increase the likelihood of AI citation.
• Limitation: Short feed posts behind login walls are invisible to AI crawlers and search engines. Do not rely on feed posts for GEO.

Actionable checklist:

• Headline includes primary keyword + value proposition (treat as meta title)
• About section written in answer-first format (quotable paragraphs)
• Featured section showcases site, case studies, key publications
• Entity names (name, company, role) consistent across LinkedIn and site
• At least one public Article published on a relevant industry topic
• LinkedIn profile URL uses custom alias (not default ID string)

For implementation details: open-graph (link previews), entity-seo (people/org sameAs), generative-engine-optimization (cross-platform GEO).

Profile Modules for Discovery

Key LinkedIn profile modules that affect search visibility and AI citation:

Module	SEO/GEO Value	Optimization
Headline	Highest—indexed, appears in search snippets	Customize beyond job title; include keyword + audience + value
About	High—indexed; citable for AI	Write in answer-first format; include proof points, external links
Featured	Medium—showcases key links on public profile	Add site URL, case studies, press, portfolio
Experience (media)	Low-medium—media attachments are indexed	Add relevant documents, links, images to each role
Skills & Endorsements	Low—indexed but thin signal	Include relevant skills; endorsements add social proof
Articles	High—indexed and rankable	Publish long-form content with keywords and data
Custom URL	Indirect—clean URL improves shareability	Set to firstnamelastname or similar

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”)
