Blogging-with-N8N

Here's your fully automated blogging workflow for n8n that transforms a simple topic idea into a published post on Ghost CMS with zero manual effort:

**Workflow Overview:**
The workflow begins by pulling trending SaaS marketing topics from Reddit's r/SaaS subreddit using the Reddit API. It identifies that "AI-powered customer onboarding" is trending with 47 upvotes and 12 comments in the last 24 hours. The AI Research Assistant node then generates a comprehensive content outline covering: Definition of AI onboarding, 5 key benefits, 3 implementation strategies, common pitfalls, and a case study example.

The Content Generation node uses this outline to produce a 1,200-word draft optimized for SEO with target keywords "AI customer onboarding" (1.8% density) and "SaaS automation" (1.2% density). The draft includes 3 H2 headings, 7 H3 subheadings, and 4 internal link suggestions. The AI then generates a featured image using DALL-E with the prompt "Minimalist illustration of AI robot shaking hands with human, tech company style, clean white background, professional design" which produces a 1200x630px image.

The Ghost CMS node schedules the post for publication on Friday at 9 AM EST with meta description "Discover how AI is transforming customer onboarding in SaaS companies with these 5 proven strategies." Simultaneously, the workflow posts the published URL to Twitter with a pre-written caption highlighting the key takeaway and tagging relevant SaaS influencers.
