WordPress SEO Automation with GPT-5 nano + Yoast SEO

Optimize your WordPress titles and meta descriptions with AI (OpenAI), update them directly in Yoast SEO, log results in Google Sheets, and receive a styled report by email.

All from your own n8n instance.

✨ Why this workflow?

Forget spending hours editing metadata manually: this flow automates SEO generation and updates with the help of AI.

• Fully documented: every block includes notes so you can easily understand how it works.
• Error-proof: reinforced with alternatives and clear alerts if something fails (nested sitemaps, blocks, etc).
• Flexible and easy to modify: change language, keywords, or domain in one single node (`OPTIONS`).
• Basic support included: designed so anyone can set it up without being an expert.

🧠 What does the workflow do?

* Reads the sitemap or internal WordPress URLs (posts or pages).

The website content is sent to *ChatGPT (GPT-5-nano)**, which analyzes it and generates a personalized SEO title and meta description for higher precision.

Updates the *Yoast SEO fields** in WordPress automatically.

Logs each result (URL, TITLE, META) into *Google Sheets**.

Sends a *professional HTML email report** with a summary of the updates.
