Create SEO blog posts with Gemini, DeepSeek and publish to WordPress

Description

An intelligent n8n workflow that automates your entire blog content pipeline—from keyword research to WordPress publishing. Using Google Gemini, DeepSeek, and Perplexity, this workflow generates SEO-optimized blog posts and publishes them automatically while tracking everything in Google Sheets.

What this workflow does

This automation handles your complete blog creation process:

Scheduled content research:** Fetches approved topics from Google Sheets and conducts deep SEO research using Perplexity
AI-powered writing:** Uses DeepSeek for competitor analysis and Google Gemini to write 800-1000 word SEO-optimized articles with FAQs
Automated publishing:** Publishes directly to WordPress via REST API and updates tracking in Google Sheets
Smart scheduling:** Runs daily at 7 AM, respects weekly frequency settings, and processes multiple clients in batches

Setup requirements

Tools you'll need:
Active n8n instance (self-hosted or n8n Cloud)
Google Sheets with OAuth access
WordPress site with REST API enabled
API keys: Google Gemini, DeepSeek, Perplexity (optional)

Estimated setup time: 20-25 minutes

Step-by-step setup

1. Prepare your Google Sheets

Create two sheets:

Client projects sheet:
Columns: Client ID | Website URL | Blog API | GMB Name | Weekly Frequency | On Page Sheet
Example: CLIENT001 | https://example.com | xxxx xxxx xxxx | Example Co | Mon,Wed,Fri | Sheet URL

Content topics sheet (one per client, named "Content Requirement & Posting"):
Columns: S.No. | Focus Keyword | Content Topic | Internal Linking URLs | Words | Topic Approval | Content Approval | Publish URLs | Weekly Frequency
Example: 1 | best investment tips | Top 10 Investment Tips | https://example.com/page | 1000 | Approved | Approved | (empty) | Mon,Wed

2. Connect Google Sheets

In n8n: Credentials → Add credential → Google Sheets OAuth2 API
Complete OAuth authentication
Open "Load Active Client Projects" node → Select your client sheet URL and credential
Open "Get Approved Blog Topics from Sheet" node → Select credential (document URL is dynamic)

3. Add AI API credentials

Google Gemini:
Get API key: https://makersuite.google.com/app/apikey
Add credential in n8n: Google PaLM API
Select in "Gemini - Content Writing Model" node

DeepSeek:
Get API key: https://platform.deepseek.com/
Add credential in n8n: DeepSeek API
Select in "DeepSeek - Research Model" node

Perplexity (optional):
Get API key: https://www.perplexity.ai/settings/api
Add credential in n8n: Perplexity API
Select in "Perplexity - Web Search Tool" node

4. Set up WordPress

WordPress admin → Users → Profile → Application Passwords
Create new application password (format: xxxx xxxx xxxx xxxx xxxx xxxx)
Add to your Google Sheet:
Blog API column: Paste application password
Website URL column: Enter full URL (e.g., https://example.com)

5. Configure schedule

Open "Daily Blog Publishing Schedule" node
Set time (recommended: 7:00 AM)
Choose timezone
Save settings

6. Test and activate

Add one test row in your sheets with today's day in Weekly Frequency
Click "Daily Blog Publishing Schedule" → Execute node
Verify: Blog published in WordPress, URL updated in Google Sheet
Toggle workflow Active at the top

How it works

1. Schedule & filtering (7 AM daily)
Loads client projects from Google Sheets
Filters clients by Weekly Frequency (e.g., only those publishing today)

2. Content fetching
Loops through each client
Fetches approved topics (Topic Approval = "Approved", Publish URLs = empty)
Selects first pending topic

3. AI content creation
Research phase:** DeepSeek + Perplexity analyze competitors, search intent, content gaps, LSI keywords
Writing phase:** Google Gemini writes 800-1000 word article with FAQs in conversational English

4. Publishing
Extracts title and body content
Publishes to WordPress via REST API
Updates Google Sheet with publish URL
Continues to next topic/client

Key features

Troubleshooting

Google Sheets not connecting:
Re-authenticate OAuth credentials
Verify sheet URLs and column names match exactly (case-sensitive)
Check sharing permissions on sheets

AI API errors:
Verify API keys are active and have credits
Check rate limits on API dashboards
Reduce token usage if hitting limits

WordPress publishing fails:
Test REST API: Visit https://yoursite.com/wp-json/wp/v2/posts
Verify application password is correct (with spaces)
Ensure user has Author/Editor role
Check Website URL includes https://

No topics being processed:
Verify Topic Approval = "Approved" and Content Approval = "Approved"
Ensure Publish URLs column is empty
Check today's day matches Weekly Frequency setting
Confirm sheet name is exactly "Content Requirement & Posting"
