Turn Reddit Questions into SEO Articles Automatically
This workflow takes real user questions from Reddit and transforms them into fully structured blog posts — title, intro, steps, and conclusion — using AI.
How it works
- Manually triggered when you want to run it
- Scrapes the latest posts from a specific subreddit (e.g.
r/n8n) - Filters only posts that are real questions (based on keywords like “how,” “what,” “why”)
- Logs relevant questions into a Google Sheet as raw input
- Enhances each question using AI (rephrases, creates a clean title and slug)
- Generates full-length blog content:
- ✏️ Intro paragraph
- ✅ Step-by-step guide
- 🧠 Clear conclusion
- Saves the final blog content to a second Google Sheet for publishing
Set up steps
- You’ll need access to:
- Reddit API (OAuth)
- OpenAI API
- Google Sheets
- Takes around 15–20 minutes to connect all the credentials and tweak prompts
- Customize the subreddit or topic focus by changing the Reddit node config
Perfect for content teams who want to scale content output using real community pain points — without ever starting from a blank page.
