Auto-Generate & Publish SEO Blog Posts to WordPress with OpenRouter & Runware

Description

Automate Blog Creation and Publishing with Ultra-Low Cost AI

This n8n workflow — BlogBlizt: Runaware Edition — automates the creation, enrichment, and publishing of SEO-optimized blog posts for WordPress using entirely free OpenRouter AI models for text and metadata generation, plus ultra-low-cost Runware AI for realistic featured images (as low as $0.0016 per image).

It’s triggered every 3 hours or manually via Telegram. Each run generates 1,500–3,500-word articles on trending topics in Technology, AI, Tech Facts, History, or Tips — all complete with catchy titles, slugs, meta descriptions, and visuals.

💰 Why This Is So Cost-Efficient

✅ Free metadata + article generation (OpenRouter free-tier models)
💸 Only cost is for image generation via Runware:
Image generation: ~$0.0016/image (the cheapest model could be $0,00065)

This is ideal for scale — generating dozens of high-quality blog posts with minimal expense.

Bloggers who want high-quality content without writing
SEO marketers seeking fresh, long-form articles
