n8n workflow automation for AI blog pipeline

What it is

The Blog Builder is an end-to-end n8n workflow that takes a domain URL and number of posts, then fully automates SEO blog creation. It fetches organic and paid keyword data, clusters them into topic groups using AI, then researches each topic via Perplexity for competitor analysis and factual grounding. It generates a structured outline, writes the full article in the business owner’s authentic voice, validates claims against the Domain Fact Check database, humanizes the content to reduce AI detection, and outputs a formatted Google Doc with the completed article, headers, and SEO metadata.
