💡 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?

1. Automatically detects the sitemap (robots.txt → sitemap.xml). 2. Filters only internal URLs (ignores assets, images, scripts, etc). 3. Fetches the full HTML content of each URL. 4. Uses ChatGPT (GPT-4o-mini) for professional diagnostics (meta tags, headings, hreflang, Open Graph, links, duplicate content, etc). 5. 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)
