In this tutorial I walk you through building a fully automated SEO workflow using n8n, the Groq API, Gemini Flash, and Google Sheets. This is the exact workflow I use to manage off-page SEO for multiple client websites.
What You Will Build
A workflow that automatically generates SEO-optimized blog post ideas, writes outlines using AI, tracks backlink opportunities in Google Sheets, and sends a weekly email report.
Prerequisites
- n8n installed locally or on a VPS
- Groq API key (free tier works perfectly)
- Google Sheets API access
- Gmail or SMTP for email reports
Step 1: Keyword Research Node
Add an HTTP Request node calling the Groq API. Using Groq Llama models keeps costs near zero while delivering excellent keyword research results.
Step 2: Content Outline Generator
Connect a second AI node that takes each keyword and generates a full blog post outline including H2s, H3s, and a meta description.
This workflow saves approximately 8 to 10 hours per week of manual SEO research.
Step 3: Log to Google Sheets
Use the Google Sheets node to append each row with the keyword, outline, and date. Set status to Draft automatically.
Step 4: Weekly Email Report
Add a Schedule Trigger set to every Monday. Connect Gmail to send a formatted summary of all keywords processed that week.
