Most people just open Google Search Console (GSC), glance at the keywords, numbers, and move on. But what is hidden in GSC is traffic, leads, and even revenue?

This article shows you how to find those hidden gold keywords using something called regex filters. Don’t worry — it sounds fancy, but it’s just a tool that helps you find the exact search terms people use to reach your site.

How to Use This GSC Regex

Here’s how to get started:

Go to Google Search Console → Performance → Add filter → Queries/Pages
Click “Queries containing” → “Custom (regex)”
Copy and paste the filters below
Sort by impressions or clicks
Build content, refine targeting, or double down on what’s working

High-Intent Discovery Filters

These patterns capture bottom-of-funnel (BOFU) searches: shoppers ready to buy, users comparing options, and customers with strong purchase intent.

Commercial Purchase Intent

Filter: .*(buy|cheap|price|purchase|order).*

What it finds: Queries containing buying signals like “buy wireless headphones,” “cheap laptop deals,” “iPhone 17 price”

Use this to: Identify which of your existing pages are attracting buyers. Optimize these pages with stronger CTAs, clearer pricing, or purchase buttons since these searchers are ready to convert.

Product Comparison Queries

Filter: .*(best|top|vs|review*).*

What it finds: Comparison searches like “best CRM software,” “Slack vs Teams,” “iPhone 17 reviews”

Use this to: See which of your pages are already attracting comparison shoppers. Double down on these pages by adding more comparison elements, competitor analysis, or buying guides since you’re already capturing this valuable traffic.

Transactional Action Signals

Filter: \b(get|download|buy|sign up|subscribe)\b

Strategic Filters for SaaS, B2B, and Ecom

These filters identify how people talk about your product category — even when they don’t use your exact brand name.
