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.

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.

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
