Prerequisites for n8n WordPress Automation

Before diving into this n8n automation tutorial, ensure you have:

n8n instance – Cloud or self-hosted
WordPress website with API access enabled
Google Sheets document for content management
Google Gemini API key for AI content generation
Basic understanding of automation workflows

Pro Tip: This workflow is designed for MBA students, entrepreneurs, AI learners, and business students who want to scale their content marketing efforts efficiently.

Step 1: Setting Up the Schedule Trigger Node

Configure Automated Content Publishing Schedule

The Schedule Trigger is the foundation of your automated content workflow. This node initiates the entire process at regular intervals.

Node Configuration:

Node Type: n8n-nodes-base.scheduleTrigger
Trigger Interval: Every 60 minutes

This configuration ensures your WordPress automation system checks for new content every 15 minutes, providing timely content publication without overwhelming your servers.

Step 2: Google Sheets Integration for Content Management

Retrieve Pending Content from Google Sheets

The Google Sheets integration acts as your content management system, storing article titles, descriptions, and publication status.

Copy this google sheet template: https://docs.google.com/spreadsheets/d/1wWJlqKCqRPbNpdA_7–VwqBKY4Pgv9t0uytqGiafGnY/edit?usp=sharing

Sheet Structure Required:

Title Column: Article headlines
Description Column: Brief content descriptions
Status Column: “Pending” or “Done”
Row Number: Auto-generated tracking

The node filters for entries with “Pending” status and uses the returnFirstMatch option to process one article at a time, ensuring systematic content publication.

Filter Configuration:

– lookupColumn: “Status”

– lookupValue: “Pending”

– returnFirstMatch: true

Step 3: AI-Powered SEO Research with Google Gemini

Automated Keyword Research and SEO Analysis

This is where the magic happens! The SEO Agent uses Google Gemini AI to perform comprehensive keyword research for each article topic.

SEO Research Components:

Primary Keywords: 3-5 high-volume, low-competition terms
Long-tail Keywords: 10-15 specific phrases
Related Keywords: 15-20 semantic variations
Content Structure: H2/H3 heading suggestions
Hashtag Research: 20-30 relevant social media tags
Competitor Analysis: Content gap identification

The AI agent analyzes your target audience (MBA students, entrepreneurs, AI learners, business students) to provide contextually relevant keyword suggestions that improve your content marketing automation effectiveness.

Step 4: Data Processing and Field Management

Structuring Data for Content Generation

The Edit Fields node organizes and structures the data flow between SEO research and content creation phases.

Field Assignments:

title: {{ $(‘Get row(s) in sheet’).item.json.Title }}

description: {{ $(‘Get row(s) in sheet’).item.json.Description }}

keywords: {{ $json.output }}

This step ensures clean data transfer and proper variable mapping for the subsequent content generation process in your automated blogging system.

Step 5: AI Content Generation with Advanced Copywriting

Creating SEO-Optimized Blog Posts

The Copywriter agent uses the SEO research to generate comprehensive, engaging blog posts optimized for search engines and user experience.

Content Specifications:

Word Count: 1800-2500 words
Format: HTML with semantic structure
SEO Density: 1-2% keyword optimization
Structure: Introduction, body sections, conclusion
Additional Elements: FAQ sections, meta tags, schema markup

This advanced AI content creation ensures every article meets professional publishing standards while incorporating your researched keywords naturally throughout the content.

Step 6: Content Formatting and HTML Processing

Optimizing Content for Web Publishing

The Code node performs crucial content cleaning and formatting to ensure proper display in WordPress.

const content = $input.first().json.output || ”;
const stringContent = String(content);const cleanContent = stringContent
.replace(/\\n{2,}/g, ‘<br>’)
.replace(/\n{2,}/g, ‘<br>’)
.replace(/\n\s*\n/g, ‘<br>’)
.replace(/^\s+|\s+$/g, ”)
.replace(/\n/g, ‘<br>’);

This processing step converts line breaks to HTML breaks, removes excessive whitespace, and ensures your automated content displays correctly in WordPress, maintaining the professional appearance of your automated blog posts.

Step 7: WordPress Publishing and Integration

Automated Content Publishing

The WordPress node handles the final step of publishing your AI-generated content directly to your website.

Publishing Configuration:

Title Source: {{ $(‘Edit Fields’).item.json.title }}
Content Source: {{ $json.cleanContent }}
API Authentication: WordPress REST API credentials
Post Status: Published (configurable)

Your WordPress automation ensures seamless content delivery while maintaining your site’s posting schedule and quality standards.

Step 8: Status Tracking and Workflow Completion

Updating Content Management System

The final Update row in sheet node marks processed content as “Done” to prevent duplicate publishing and maintain organized content tracking.

Update Configuration:

row_number: {{ $(‘Get row(s) in sheet’).item.json.row_number }}

Status: “Done”

This ensures your content automation workflow remains organized and prevents the same article from being processed multiple times.
