AI Content Automation Pipeline — n8n + GPT-4o + WordPress
Add a topic to your Google Sheet, run your n8n workflow, and wake up to a fully written, published blog post. Our content pipeline handles ideation-to-publish — SEO-optimised, on-brand, and logged back to your sheet — while you focus on the business.
Build My Content PipelineWhat We Build
A fully automated n8n content factory that takes a topic and produces a publish-ready piece of content — without you writing a single word. Built to run on a schedule or on demand.
Google Sheets Topic Reader
n8n reads your content calendar from a Google Sheet — picking up rows marked as "Ready" with title, target keyword, tone, and word count. After publishing, the row is updated automatically with the live URL and status.
GPT-4o Content Generation
We engineer a system prompt that defines your brand voice, SEO structure (H1/H2/H3 hierarchy, meta description, target keyword density), and content length. GPT-4o generates a fully formatted article or social post on each run.
WordPress REST API Publishing
n8n calls the WordPress REST API to create or update posts — setting title, content, excerpt, categories, tags, featured image, and publish status (draft or live). Works with any self-hosted WordPress site or WP.com Business plan.
Output Logging & Status Tracking
After publishing, n8n writes the post URL, publish date, word count, and status back to your Google Sheet. You always have a live record of every piece published and when.
Optional: Image Generation & Social Distribution
Extend the pipeline with DALL·E 3 or Unsplash API for featured images, and add social post generation for LinkedIn, Twitter/X, or Facebook — auto-scheduled via Buffer or posted directly.
Our Build Process
1. Content Strategy & Prompt Design
We review your existing content, define your voice guidelines, and engineer the GPT-4o prompt to match your SEO and brand standards.
2. Google Sheets Schema Setup
We design the sheet columns (title, keyword, tone, status, URL) and configure the n8n Google Sheets trigger with proper OAuth authentication.
3. n8n Workflow Build
Build the full n8n workflow: Sheets reader → OpenAI call → content formatting → WordPress API post → Sheets updater. Add error handlers and retry logic.
4. WordPress Integration & Testing
Configure WordPress REST API credentials, map content fields, test with draft posts, and validate formatting and SEO metadata.
5. Schedule, Handoff & Documentation
Set up a cron trigger (daily, weekly, or on-demand), record a walkthrough Loom, and deliver full documentation so you can manage the pipeline independently.
