Turn YouTube Videos into SEO Blog Posts with n8n (GPT-4o + Whisper, Auto-Published)

Every YouTube video you publish is also a blog post you haven't written yet. The content is already there — it just needs to be transcribed, restructured for reading, optimized for search, and published. n8n does exactly that: point it at a video and get a ready-to-rank article out the other side.

The problem: great video content never becomes searchable text

Video doesn't rank in Google the way a well-structured article does, and manually turning a 15-minute video into a polished blog post takes hours of transcribing, editing, and formatting. So creators leave huge amounts of SEO traffic on the table because repurposing is too much work to do consistently.

How the n8n workflow solves it

This workflow pulls the video's audio, transcribes it with Whisper, then uses GPT-4o to restructure the transcript into a readable, SEO-optimized article with headings and a meta description — and publishes it automatically to your blog.

  • Takes a YouTube URL as the input
  • Transcribes the audio accurately with Whisper
  • GPT-4o rewrites the transcript into a structured, readable article
  • Generates an SEO title, headings, and meta description
  • Auto-publishes to your CMS (Ghost, WordPress, etc.)
