Every time ChatGPT uses its web search tool, it fires off internal search queries to gather real-time information — and those queries are pure keyword gold. This guide shows you exactly how to capture them at scale.
When you ask ChatGPT a question requiring current information, it formulates search queries and sends them to a web search API. A single prompt about B2B SaaS marketing might generate queries like B2B SaaS content marketing strategies 2026, content marketing ROI software companies, and SaaS blog SEO best practices — all rankable keywords.
Install GPT Query Extractor from the Chrome Web Store. Works on Chrome, Edge, Brave, and Arc. No account needed.
Create a plain text file with one prompt per line. Prompts that force web search work best:
Example: "Research the latest statistics on email marketing open rates in 2026 and compare the top 5 email platforms for B2B companies."
Set your delay to 30 seconds between prompts to mimic human typing speed. A 50-prompt session runs fully automated in about 25 minutes and typically captures 150–250 unique queries.
Export as CSV for spreadsheet analysis or JSON for programmatic processing. Open in Google Sheets, sort by query length — longer queries (5+ words) are usually low-competition long-tail keywords perfect for blog content.
