I’m a Supply Chain Data Scientist and content creator who writes regularly about data-driven optimization, logistics, and sustainability. Promoting blog articles on LinkedIn used to be a manual task — until I decided to automate it with N8N and GPT-4o.

This workflow lets you automatically extract blog posts, clean the content, and generate a professional LinkedIn post using an AI Agent powered by GPT-4o — all in one seamless automation.

Save hours of repetitive work and boost your reach with AI.

Who is this template for?

This template is perfect for:

– Bloggers and writers who want to promote their content on LinkedIn
– Marketing teams looking to automate professional post-generation
– Content creators using Ghost platforms

It generates polished LinkedIn posts with:

– A hook
– A quick summary
– A call-to-action
– A signature to drive readers to your contact page

How does it work?

This workflow runs in N8N and performs the following steps:

🚀 Triggers manually or you can add a scheduler

📰 Pulls recent blog posts from your Ghost site (via API)

🧼 Cleans the HTML content for AI input

🤖 Sends content to GPT-4o with a tailored prompt to create a LinkedIn post

📄 Records all data (post content + LinkedIn output) in a Google Sheet

What do I need to start?

You don’t need to write a single line of code.

Prerequisites:

– A Ghost CMS account with blog content
– A Google Sheet to store generated posts
– An OpenAI API Key
– Google Sheets API connected via OAuth2

Next Steps

Use the sticky notes in the workflow to understand how to:

– Add your Ghost API credentials
