Instantly map all internal URLs, perform AI-powered (ChatGPT) analysis, and deliver results in HTML via webhook, Google Sheets, or email.
All from your own n8n instance!
💡 Why this workflow?
- Forget expensive tools: Run deep, visual audits replacing Screaming Frog or Ahrefs.
- Real URL mapping: Reads the sitemap, filters only internal URLs, and analyzes each one individually.
- AI-powered analysis: ChatGPT detects critical issues, recommendations, and best practices on every page.
- Error handling: The workflow includes robust error handling and guides you on what to do in each case.
- Client-ready results: Receive a professional HTML report, an email summary, or push it to Google Sheets for team collaboration.
- Automate by webhook or manually: Use it in backend integrations or trigger with a button.
🧠 What does the workflow do?
-
Automatically detects the sitemap (robots.txt → sitemap.xml).
-
Filters only internal URLs (ignores assets, images, scripts, etc).
-
Fetches the full HTML content of each URL.
-
Uses ChatGPT (GPT-4o-mini) for professional diagnostics (meta tags, headings, hreflang, Open Graph, links, duplicate content, etc).
-
Groups results (critical issues, recommendations, best practices) and presents them as:
- 📄 Professional HTML report (ready to send/share)
- 📊 Google Sheets (collaborative structure)
- 🔗 Webhook or HTML email (for automation)
🛠️ Technologies / APIs Used
- n8n (self-hosted or cloud instance required)
- ChatGPT API (required, approx. cost: €0.01 per 20 URLs analyzed)
- Google Drive/Sheets API (only for Google Sheets output)
- Email SMTP/Gmail (for notifications)
⚡ Who should use it?
- SEOs and agencies needing technical reports in minutes
- Freelancers automating client SEO audits
- Web developers and growth hackers
- Website owners/businesses with multiple sites
🎯 Problems solved
- Slow, manual SEO auditing
- Dependence on expensive SaaS
- Lack of full-site coverage → every URL is checked with actionable recommendations
- Fast, visual delivery to clients (HTML “copy-paste” report and/or collaborative sheet)
