n8n AI SEO Content Optimization with SERP Analysis & Slack Approval

Input SEO draft → AI optimizes using history, SERP data, and knowledge base → structured JSON output → Slack human approval → save to Google Sheets

Read the case’s method and prerequisites

Prerequisites: n8n instance; OpenAI API key; Google Sheets OAuth2; SerpAPI key; Slack Bot Token with chat:write; Pinecone API key with existing index; a Google Sheet with a content_versions tab. Costs: pay-per-use for each API; OpenAI uses gpt-4o-mini. Limitations: template contains placeholders [Your Google Sheet ID], [Your Slack Channel ID], and a Pinecone index name that must be replaced. Save Approved Draft to Sheet has field mapping mismatches (tone←improvements, topic←title, context_used←content_id) — verify column names before running. Check Human Approval Status lacks a reject branch. AI Agent output triggers both Sheets save and Slack approval in parallel, creating risk of saving before approval. Not tested by this site.
