Automate Google Ads Keyword Planning with AI & n8n

Transform your Google Ads keyword research from hours of manual work into a fully automated, AI-powered process that delivers production-ready keyword strategies directly to Google Sheets. This n8n workflow seamlessly connects Google Keyword Planner, OpenAI's chat models, and Google Sheets to create comprehensive keyword plans with real search data and intelligent business context analysis.

What this workflow does

This automated keyword planning pipeline eliminates the tedious process of manually exporting and analyzing keyword data:

• Form submission capture: Users input website URL, company name, industry/niche, seed keywords, and products/services through an integrated form
• Google Keyword Planner integration: Automatically retrieves keyword ideas with authentic search volume, competition levels, and CPC bid ranges
• AI-powered analysis: OpenAI chat model (GPT-5.4-mini) evaluates keywords within your business context, scoring relevance and classifying search intent (informational, navigational, commercial, transactional)
• Intelligent categorization: Keywords are automatically tagged by type (branded, competitor, product, application) and the AI generates additional high-intent keyword suggestions
• Structured Google Sheets output: Delivers two comprehensive sheets - an AI-enriched keyword strategy document and raw Keyword Planner results for reference
