Who is this for?

Bloggers, content marketers, and WordPress site owners who want high-quality, SEO-ready content without manual writing or formatting.

What problem is this workflow solving?

Writing good blog posts takes time and skill: ideas, drafts, images, SEO fields, publishing. BlogBlitz automates the whole chain, from topic to published post plus a notification, so your site stays active and easy to find.

What this workflow does

• Triggers: Runs every 3 hours via a Schedule Trigger, or on demand with the Telegram command ("generate").
• Generates Content: Uses OpenRouter to pick a category (e.g., Technology, AI) and create a title, slug, focus keyphrase, and meta description.
• Writes Articles: OpenAI crafts 1,500–2,500-word posts with SEO-friendly structure, headings, and a call-to-action.
• Adds Visuals: Generates realistic featured images with OpenAI and uploads them to WordPress.
• SEO Features: Generates optimized slug, focus keyphrase, and meta description.
• Publishes: Posts articles to WordPress with proper categories and featured images.
• Notifies: Sends publish alerts with links to Discord and Telegram.
