LinkedIn Marketing
Overview
This skill helps AI agents create high-performing LinkedIn content and integrate with the LinkedIn API. It covers platform-specific content rules, post formatting, carousel creation, API-based publishing, analytics tracking, and growth strategies tailored to LinkedIn's algorithm and audience behavior.
Instructions
Platform Rules & Algorithm
LinkedIn's algorithm in 2025-2026 prioritizes:
- Dwell time — how long people spend reading your post (long-form > short)
- Early engagement — first 60-90 minutes are critical for distribution
- Comments > reactions — comments weight 5-8x more than likes
- Native content — no external links in post body (kills reach 40-50%)
- Relevance — content shown to people interested in the topic, not just connections
- Consistency — 3-5 posts/week beats 1 viral post/month
What kills reach:
- External links in post body (put in comments instead)
- Editing post within first hour
- Engagement pods (LinkedIn detects and suppresses)
- Hashtag stuffing (3-5 max)
- Tagging people who don't engage back
Content Formats & Best Practices
Text Posts (Highest organic reach)
[Hook — first 2 lines are everything, must stop the scroll]
[Line break after every 1-2 sentences for mobile readability]
[Body — story, insight, or framework. 800-1300 characters optimal]
[Each paragraph is 1-3 short sentences max]
[CTA — question to drive comments, not "like if you agree"]
[3-5 relevant hashtags at the bottom]
Formatting rules:
- First 2 lines show before "...see more" — make them irresistible
- Use line breaks aggressively — wall of text = scroll past
- 800-1300 characters is the sweet spot (long enough for dwell time, short enough to finish)
- Emojis sparingly as bullet markers (🔹, →, ✅), not decoration
- No markdown — LinkedIn doesn't render it. Use CAPS or emojis for emphasis
- End with a question to drive comments (open-ended, not yes/no)
Carousels (PDF documents — highest save rate)
- Upload as PDF (each page is a slide)
- Slide size: 1080x1350px (4:5 ratio) or 1080x1080px (1:1)
- 8-12 slides optimal
- First slide = hook/title (bold, minimal text)
- Last slide = CTA + profile summary
- One idea per slide, large text (24-32pt minimum)
- Brand colors and consistent design
- File size: under 100MB, max 300 pages
Polls (High engagement, low effort)
- 2 weeks duration optimal
- 3-4 options (not 2 — too binary)
- Add context in the post body explaining why you're asking
- Follow up with results analysis post
Articles & Newsletters
- Articles: 1000-2000 words, SEO-indexed by Google
- Newsletters: subscribers get email + in-app notification
- Good for long-form thought leadership
- Lower viral potential but higher authority building
- Include images every 300-400 words
Video
- Native video (not YouTube links)
- Vertical (9:16) or square (1:1) — NOT widescreen
- Under 2 minutes for feed (30-90s optimal)
- Captions mandatory (80%+ watch without sound)
- Hook in first 3 seconds
- Max file size: 5GB, max duration: 15 minutes
LinkedIn API Integration
Authentication (OAuth 2.0)
// LinkedIn uses OAuth 2.0 with 3-legged flow
const LINKEDIN_AUTH_URL = 'https://www.linkedin.com/oauth/v2/authorization';
const LINKEDIN_TOKEN_URL = 'https://www.linkedin.com/oauth/v2/accessToken';
// Step 1: Redirect user to authorize
const authUrl = new URL(LINKEDIN_AUTH_URL);
authUrl.searchParams.set('response_type', 'code');
authUrl.searchParams.set('client_id', process.env.LINKEDIN_CLIENT_ID);
authUrl.searchParams.set('redirect_uri', process.env.LINKEDIN_REDIRECT_URI);
authUrl.searchParams.set('scope', 'openid profile email w_member_social');
// Redirect user to authUrl.toString()
// Step 2: Exchange code for token
const tokenResponse = await fetch(LINKEDIN_TOKEN_URL, {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: new URLSearchParams({
grant_type: 'authorization_code',
code: authorizationCode,
client_id: process.env.LINKEDIN_CLIENT_ID,
client_secret: process.env.LINKEDIN_CLIENT_SECRET,
redirect_uri: process.env.LINKEDIN_REDIRECT_URI,
}),
});
const { access_token, expires_in } = await tokenResponse.json();
// Token valid for 60 days, refresh before expiry
Post Content via API
// Get user profile URN
const profileRes = await fetch('https://api.linkedin.com/v2/userinfo', {
headers: { Authorization: `Bearer ${access_token}` },
});
const { sub: personUrn } = await profileRes.json();
// Create a text post
const postRes = await fetch('https://api.linkedin.com/v2/posts', {
method: 'POST',
headers: {
Authorization: `Bearer ${access_token}`,
'Content-Type': 'application/json',
'X-Restli-Protocol-Version': '2.0.0',
'LinkedIn-Version': '202401',
},
body: JSON.stringify({
author: `urn:li:person:${personUrn}`,
commentary: 'Your post text here...',
visibility: 'PUBLIC',
distribution: {
feedDistribution: 'MAIN_FEED',
targetEntities: [],
thirdPartyDistributionChannels: [],
},
lifecycleState: 'PUBLISHED',
}),
});
// Create a post with image
// Step 1: Initialize upload
const uploadRes = await fetch('https://api.linkedin.com/v2/images?action=initializeUpload', {
method: 'POST',
headers: {
Authorization: `Bearer ${access_token}`,
'Content-Type': 'application/json',
},
body: JSON.stringify({
initializeUploadRequest: {
owner: `urn:li:person:${personUrn}`,
},
}),
});
const { value: { uploadUrl, image: imageUrn } } = await uploadRes.json();
// Step 2: Upload image binary
await fetch(uploadUrl, {
method: 'PUT',
headers: { 'Content-Type': 'image/png' },
body: imageBuffer,
});
// Step 3: Create post with image
await fetch('https://api.linkedin.com/v2/posts', {
method: 'POST',
headers: {
Authorization: `Bearer ${access_token}`,
'Content-Type': 'application/json',
'LinkedIn-Version': '202401',
},
body: JSON.stringify({
author: `urn:li:person:${personUrn}`,
commentary: 'Post with image...',
visibility: 'PUBLIC',
distribution: {
feedDistribution: 'MAIN_FEED',
},
content: {
media: {
id: imageUrn,
title: 'Image title',
},
},
lifecycleState: 'PUBLISHED',
}),
});
Company Page Posting
// Post as company page (requires r_organization_admin + w_organization_social)
await fetch('https://api.linkedin.com/v2/posts', {
method: 'POST',
headers: {
Authorization: `Bearer ${access_token}`,
'Content-Type': 'application/json',
'LinkedIn-Version': '202401',
},
body: JSON.stringify({
author: 'urn:li:organization:12345678',
commentary: 'Company update...',
visibility: 'PUBLIC',
distribution: { feedDistribution: 'MAIN_FEED' },
lifecycleState: 'PUBLISHED',
}),
});
Analytics
// Get post analytics (requires r_organization_social scope for org posts)
const analyticsRes = await fetch(
`https://api.linkedin.com/v2/organizationalEntityShareStatistics?q=organizationalEntity&organizationalEntity=urn:li:organization:12345678&timeIntervals.timeGranularityType=DAY&timeIntervals.timeRange.start=1704067200000&timeIntervals.timeRange.end=1706745600000`,
{ headers: { Authorization: `Bearer ${access_token}` } }
);
// Personal post metrics via ugcPosts
const ugcRes = await fetch(
`https://api.linkedin.com/v2/socialMetadata/${postUrn}`,
{ headers: { Authorization: `Bearer ${access_token}` } }
);
Growth Strategy
Posting schedule: 3-5x/week (Tue-Thu peak engagement, 8-10 AM local time)
Content mix:
- 40% educational (frameworks, how-tos, lessons learned)
- 25% stories (personal experiences, behind-the-scenes)
- 20% opinion/contrarian takes (drives comments)
- 10% engagement posts (polls, questions)
- 5% promotional (product, hiring, announcements)
Comment strategy:
- Reply to every comment on your posts within 2 hours
- Leave 5-10 thoughtful comments/day on posts in your niche
- Comments on big accounts get you visibility to their audience
- Ask follow-up questions in comments to extend threads
Examples
Example 1: Write a LinkedIn post announcing a product launch
User prompt: "Write a LinkedIn post for me. I'm the CTO of Meridian Analytics and we just launched a real-time data pipeline product called StreamFlow that processes 2 million events per second. Target audience is engineering leaders at mid-size SaaS companies."
The agent will draft a LinkedIn text post optimized for the algorithm. The first two lines hook with: "We spent 14 months building something we couldn't find anywhere else.\n\nToday we're launching StreamFlow — a real-time data pipeline that handles 2M events/sec with sub-10ms latency." The body tells the story of the problem (batch processing delays costing customers $40K/month in stale dashboards), the solution, and early results from beta customers. It ends with an open-ended question: "What's the biggest bottleneck in your data pipeline today?" followed by 4 hashtags: #DataEngineering #RealTimeAnalytics #SaaS #ProductLaunch. The link to the product page goes in a separate first comment, not in the post body.
Example 2: Automate posting to a LinkedIn company page via API
User prompt: "Build a TypeScript function that posts a weekly engineering blog summary to our LinkedIn company page (Meridian Analytics, org ID 91847362) every Monday at 9 AM EST."
The agent will create a TypeScript module that authenticates with LinkedIn OAuth 2.0 using LINKEDIN_CLIENT_ID and LINKEDIN_CLIENT_SECRET from environment variables, obtains an access token with w_organization_social scope, then calls POST /v2/posts with author: "urn:li:organization:91847362", the formatted blog summary as commentary, visibility: "PUBLIC", and lifecycleState: "PUBLISHED". The function is wrapped in a cron scheduler using node-cron with the pattern 0 9 * * 1 (Mondays at 9 AM). It includes token refresh logic to handle the 60-day expiry and logs each post's success or failure to a linkedin-posts.log file.
Guidelines
- Put links in the FIRST COMMENT, never in the post body
- Write for mobile — 60%+ of LinkedIn users are on phones
- Don't edit posts in the first hour — it resets distribution
- Use "I" not "we" for personal posts — LinkedIn is personal-first
- Tag max 3-5 people per post, only if they'll actually engage
- Post consistently at the same times — your audience learns when to expect you
- Repurpose high-performing posts after 3-4 months — new followers haven't seen them
- Save carousels as PDF at 1080x1350px for optimal mobile display
