GSC Regex for Custom Data Segmentation

← SEO Tactic Library

What It Is

Use regex (regular expression) filters in Google Search Console’s Performance report to segment keyword data by pattern — isolating branded vs. non-branded queries, filtering by question type, by location indicator, or by content category — without needing to export data to a spreadsheet. This unlocks analysis that GSC’s default filters cannot perform.

How It Works

1. Open the GSC Performance report, click the + New button, select Query, then choose Custom (regex) as the filter type — this activates regex-based query filtering
2. Use brand isolation patterns: enter your brand name as a regex pattern like brand.* to see all queries containing your brand name, then invert (doesn’t contain) to see only non-branded performance
3. Use question-type patterns like (?i)(how|what|why|when|where|who) to filter for all informational/question queries and measure their combined CTR, position, and impression share
4. Use negative lookahead to filter out branded queries from your non-branded view: ^(?!.*(brand|your company name)).*$ — this shows only pure non-branded search performance
5. Export the filtered view as a CSV and compare date ranges to identify seasonal trends, content decay, or the impact of recent changes on specific query segments
