Generate RE2-compatible regular expressions for Google Search Console. Describe what you want to filter in plain English — get a copy-ready regex pattern with examples and step-by-step GSC instructions.
Google Search Console uses RE2 regex syntax, which is a fast, safe regular expression engine developed by Google. RE2 does NOT support lookaheads (?=), lookbehinds (?<=), or backreferences (\1). It supports basic features: character classes [a-z], alternation (a|b), quantifiers (+, *, ?, {n}), anchors (^ and $), groups (), and common escapes (\d, \w, \s). The maximum pattern length is 4096 characters.
You can use regex filters in two places in GSC: 1) The Performance report — filter by queries or pages using 'Custom (regex)' match type. Click '+ New' filter, select Query or Page, change the match type to 'Custom (regex)', and enter your pattern. 2) URL Inspection — for checking specific URL patterns. Regex filters are powerful for analysing branded vs non-branded queries, specific URL segments, or query patterns.
Common GSC regex patterns include: branded queries (your brand name with variations: brand|brnd|b-rand), blog posts (/blog/.*), URLs with parameters (\?.*utm_), specific page types (/products/[^/]+$), queries containing specific words (.*bootstrap.*template.*|.*template.*bootstrap.*), and excluding patterns (use the 'Doesn't match' option with your regex). Combine patterns with | (OR) for complex filters.
