Automate LinkedIn Company Search & AI Scoring with n8n and Google Sheets

What This Automation Does

This workflow searches LinkedIn companies using set filters, gets company details, scores companies with AI, and adds good companies to a Google Sheets CRM.

It solves the pain of spending too much time manually finding good leads on LinkedIn.

The result is a cleaner, scored list of companies, ready for sales follow-up.

How the Workflow Works: Inputs, Processing, and Output

Inputs

• Company search criteria like industry, location, and company size.
  
• Positive and negative indicators for AI scoring.
  
• API keys for Ghost Genius, Google Sheets, and OpenAI.
  

Processing Steps

1. The Set Variables node collects target criteria and scoring indicators.
   
2. The Search Companies node calls the Ghost Genius API to find LinkedIn companies matching criteria.
   
3. The Extract Company Data node splits the response into individual companies.
   
4. The Process Each Company node works through each company one by one with a short wait to avoid API limits.
   
5. The Get Company Info node retrieves detailed info like website and followers.
   
6. The Filter Valid Companies node removes companies without websites or under 200 followers.
   
7. The Check If Company Exists node looks in Google Sheets to avoid duplicates.
   
8. If new, the AI Company Scoring node uses OpenAI to give each company a score from 0 to 10, based on fit.
   
9. A wait node pauses to respect Google Sheets limits.
   
10. The Add Company to CRM node appends the qualified company info and score to Google Sheets.
    
11. The workflow loops back to process the next company until done.
    

Outputs

• Updated Google Sheets CRM with new, scored companies.
  
• A better, easier-to-use list of leads.

Customization Ideas

• Change company size filters in the Set Variables node to target specific business sizes.
  
• Adjust follower count thresholds in the Filter Valid Companies node to make lead quality stricter or looser.
  
• Edit positive and negative indicators in the variables to refine how AI scoring judges company fit.
  
• Switch Google Sheets to Airtable or another CRM by replacing Google Sheets nodes with API calls.
  
• Increase pages fetched in the Search Companies node to pull more results, respecting API limits.
  

Potential Errors and How to Fix Them

  Cause: Ghost Genius API key is wrong or expired.
  Fix: Update the API key in HTTP headers and confirm it's active.
  
• Error: "Google Sheets append operation failed due to quota limits".
  Cause: Too many requests hitting Google Sheets API limit.
  Fix: Increase delay in wait nodes, reduce batch size.
  
• Error: AI scores look wrong or unrelated.
  Cause: AI prompt indicators missing or not clear.
  Fix: Improve positive and negative indicators in Set Variables node.
