Generating Keywords & Search Volumes via Google Ads API

This n8n workflow streamlines keyword research by using the Google Ads API to generate expanded keyword ideas from seed keywords, complete with accurate monthly search volume data. It improves upon simpler methods like Google Autosuggest by providing reliable metrics directly from Google's ecosystem, ideal for SEO optimization and ad campaign planning.

Key benefits include significant time savings on manual research, access to high-quality data without third-party tools, and seamless integration into broader marketing automations. Users can input keyword arrays, configure location/language targeting, and output structured data ready for spreadsheets or databases, reducing errors and enhancing decision-making.

Use cases span SEO content strategies, PPC bid optimization, competitor analysis, and ongoing campaign monitoring. Trigger it via webhooks for real-time updates or schedule for periodic refreshes. Pair with Google Sheets for easy visualization and reporting.

Setup is straightforward: replace the trigger, map keywords to the 'Set Keywords' node, update the Google Ads API URL with your customer ID (e.g., https://googleads.googleapis.com/v18/customers/{customer-id}:generateKeywordIdeas), add developer token and headers, then process results through split and set nodes for storage.
