Setup

1. Install from npm

npm install -g dataforseo-cli

2. Check credentials

dataforseo-cli status

If credentials are already configured, you're good to go. If not, authenticate:

# With login + password
dataforseo-cli --set-credentials login=YOUR_LOGIN password=YOUR_PASSWORD

# Or with base64 token (from DataForSEO email)
dataforseo-cli --set-credentials base64=YOUR_BASE64_TOKEN

Workflow: SEO Article Research

1. Start with seed keyword: dataforseo-cli volume "your topic"
2. Expand: dataforseo-cli related "your topic" -n 30
3. Filter: Pick keywords with volume > 100, difficulty < 60
4. Check competitors: dataforseo-cli competitor competitor-domain.com -n 20
5. Write article targeting the best keyword cluster

Tips

• Batch keywords in volume — DataForSEO charges per API request, not per keyword
• Default location is USA (2840). Always set --location for local/international SEO
• Use locations and languages without arguments to see all available options
• Difficulty scale: 0-30 easy, 31-60 medium, 61-100 hard
