LLM Content Creation and Publishing with Claude: SEO Blogs, Emails, and Social Media Posts

This workflow automates enterprise-grade content creation, replacing manual drafting in Google Docs or WordPress that involves brainstorming, researching via Google Scholar, fact-checking, and SEO tweaks—labor-intensive processes consuming 25-40 hours weekly for marketing teams producing 10+ pieces, prone to plagiarism flags and inconsistent quality. It processes requests via webhook, validates inputs (10-1000 char queries), configures specs (type: blog/article/email/social, audience/tone/keywords/wordcount), filters safety (blocks harmful topics), uses Claude 3.5 Sonnet via Langchain agent to generate HTML content with research via Tavily tool (advanced search, credible sources, max 8 results), analyzes quality (word variance, citations, SEO density, score >=75% for publish), gates high-scorers for CMS auto-post, and audits via webhooks. Key nodes: ExecuteWorkflowTrigger (JSON: query, type, audience, etc.), IF validations (length, safety regex), Set for config/session, lmChatAnthropic (maxTokens=4000, temp=0.7), HTTP Tool (Tavily POST: query, depth=advanced, sources .edu/.gov/.org), Agent (prompt: standards for structure/citations/SEO, 100% original), Code analyzer (scores: 25% word accuracy, 20% HTML, 25% citations>=3, 15% keywords, 15% length>500), IF gate (>=75), HTTP publishes (CMS webhook: title/content/analytics), HTTP audit (event: creation, metrics). This equips marketing/comms teams at enterprises (100-500 employees) in tech/finance generating blogs/emails, ensuring compliant, optimized output without junior writers.\n\nBy streamlining from brief to publish, it saves 30-35 hours/week on 15 pieces, cuts revision cycles 60% and boosts SEO traffic 25% via keyword integration—ROI 350% in 4 months for thought leadership.
