+description: GTM QA - tag firing verification, trigger testing, naming conventions, cross-platform validation
+---
+
+# GTM Validator
+
+Verify GTM implementations on live pages. Test triggers, validate dataLayer, check naming conventions.
+
+## Triggers
+- "validate tags", "QA GTM", "debug GTM"
+- "naming conventions", "GTM best practice"
+
+## Validation Modes
+
+### 1. Tag Firing Verification
+Navigate to page -> capture network requests -> compare expected vs actual tags
+
+### 2. Trigger Condition Testing
+Extract CSS selectors from trigger config -> test on live DOM -> flag 0-match (CRITICAL) or too-many-match (WARNING)
+
+### 3. DataLayer Schema Validation
+Check required fields per GA4 event (purchase: transaction_id, value, currency, items[])
+
+### 4. Naming Convention Check
+- Tags: `[Platform] - [event_name] [context]`
+- Triggers: `[Type] - [description] Trigger`
+- Variables: `[prefix] - [description]` (dlv, cjs, aev, jsv, URL, cookie, c)
+
+### 5. Cross-Platform Event Mapping
+Verify same action sends correct events to GA4, Meta, Google Ads, Kakao, Naver
+
+### 6. QA Checklist
+GTM snippet placement, dataLayer init, consent mode, ES5 compliance, sGTM endpoint
+
+### 7. Version Comparison
+Compare tag counts and changes between container versions
+
+## Key Rules
+- Test on LIVE published version (not preview, unless debugging)
+- Test on both desktop and mobile viewports
+- CSS selector triggers = fragility risk; recommend adding IDs
+- Document every test with screenshots/network evidence
