Boost YouTube SEO: Automate Descriptions & Tags with AI

Transform Any YouTube Video into a Complete SEO Package in Minutes

Stop spending hours writing YouTube descriptions manually. This n8n workflow takes any YouTube video URL and automatically generates a complete SEO optimization package using AI — including descriptions with embedded chapters, keyword tags, hashtags, and SEO notes — all saved directly to Google Sheets and ready to paste into YouTube Studio.

What This Workflow Does

Simply submit your YouTube video URL along with your video title, channel name, niche, focus keyword, and section query. The workflow immediately launches two WayinVideo APIs simultaneously for maximum efficiency:

• Parallel processing: Summarization API and Find Moments API run at the same time, not sequentially, so total processing time equals running just one API
• Independent polling loops: Each API operates with its own 90-second initial wait and 30-second retry cycles — neither blocks the other if processing times vary
• Intelligent merging: Once both APIs complete, results are combined and fed to GPT-4o-mini for comprehensive SEO package generation
• Complete output: Generates 800-1000 character descriptions with embedded chapters, standalone chapter lists, 15 keyword tags, 6 hashtags, above-the-fold hooks, and detailed SEO notes
• Automatic storage: Everything saves to Google Sheets as one organized row with "Ready" status for immediate YouTube Studio deployment

Perfect Use Cases

• YouTube creators publishing multiple videos weekly who need consistent SEO optimization
• Video agencies managing content for multiple clients and channels
• Content managers streamlining post-production workflows and eliminating manual description writing
• Educational channels requiring detailed chapter breakdowns and keyword optimization
