⚡ 193 views · 🎬 Content Creation & Video

💡 Pro Tip — If you’re pulling LinkedIn data through HTTP requests or dealing with API restrictions, there’s a community node called ScraperNode that handles this natively. It has dedicated scrapers for profiles, companies, jobs, and people search — you just pass a URL and get structured data back.

Description

Who’s it for

This workflow is ideal for:

• Content creators who want to replicate successful LinkedIn strategies
• Social media managers monitoring competitor content performance
• Marketing teams analyzing trending topics in their industry
• Personal brands looking to create data-driven content
• Agencies managing multiple LinkedIn accounts

What it does

This comprehensive workflow automates the entire LinkedIn content lifecycle: it scrapes viral posts from target accounts, analyzes engagement patterns, identifies trending topics, generates original AI-powered content based on those trends, creates accompanying images, and automatically publishes to your LinkedIn profile or company page.

How it works

Phase 1: Data Collection (Runs every 12 hours)

• Scheduler triggers the workflow twice daily
• Fetches LinkedIn profile URLs from Google Sheets
• Processes profiles in batches of 3 to respect API limits
• Uses Apify API to scrape recent posts from each profile
• Adds 3-second delays between requests to avoid rate limiting
• Filters for high-engagement posts (20+ likes, comments, or reposts)
• Saves viral posts to Google Sheets with full metadata

Phase 2: Content Generation (Triggered by new data)

• Monitors Google Sheets for new viral posts every minute
• Filters posts published within the last 3 days that haven’t been analyzed
• Aggregates trending content into a single dataset
• Analyzes patterns using Google Gemini AI to identify:
  • Common themes and topics
  • Engagement triggers and hooks
  • Successful content structures
  • Trending hashtags and formats
• Generates original LinkedIn post with proper formatting
• Creates AI image prompt optimized for minimal text
• Generates professional image using Google Imagen
• Publishes complete post to your LinkedIn account
• Marks analyzed posts as complete to prevent duplication

Setup steps

1. Configure Google Sheets

• Create a new Google Sheet with two tabs:
  • Tab 1: “usernames & links” - Add LinkedIn profile URLs you want to monitor
  • Tab 2: “scrape data” - Leave empty (auto-populated by workflow)
• Connect your Google Sheets credentials in both nodes
• Replace all instances of YOUR_GOOGLE_SHEET_ID with your actual sheet ID
• Replace SHEET_GID values with your actual sheet GIDs

2. Set up Apify API

• Sign up for Apify account and get API token
• Replace YOUR_APIFY_API_TOKEN in “Scrape LinkedIn Posts API” node
• Note: Apify has free tier with limited requests

3. Configure Google Gemini credentials

• Obtain Google PaLM API credentials
• Add credentials to both “Google Gemini Chat Model” and “Generate an image” nodes

4. Set up LinkedIn publishing

• Connect your LinkedIn credentials in “Publish to LinkedIn” node
• If posting as organization, replace YOUR_LINKEDIN_ORGANIZATION_ID with your company page ID
• If posting as individual, change “postAs” parameter to “person”

5. Configure scheduling

• Default schedule: every 12 hours
• Adjust “LinkedIn Content Automation Scheduler” trigger if needed
• Consider your API rate limits when changing frequency

6. Test the workflow

• Manually trigger Phase 1 to scrape posts
• Verify data appears in Google Sheets “scrape data” tab
• Wait for Phase 2 trigger or manually activate it
• Check that content is generated and published correctly
• Verify posts are marked as analyzed in Google Sheets

Requirements

• Google Sheets API access (free)
• Google Sheets Trigger OAuth2 (free)
• Apify API token (free tier available, $49/month for more)
