Debug Google Consent Mode
Last updated: March 18, 20265 min readIntermediateBrandDeveloper
If Google Ads, GA4, or other Google services show consent signal issues, use these debugging steps to verify Arqam360's GCM v2 implementation.
Debugging Tools
- Google Tag Assistant (tagassistant.google.com) — Real-time consent state monitoring
- Browser DevTools Console — View gtag() calls and consent events
- Google Ads Diagnostics — Check consent coverage in your Google Ads account
- GA4 DebugView — See real-time events and consent parameters
1
Open Tag Assistant
Go to tagassistant.google.com and connect to your website.
2
Check consent state
In the Consent tab, verify you see 'denied' for all parameters on page load.
3
Accept consent
Click accept on your consent banner.
4
Verify update
Check Tag Assistant shows consent parameters changing to 'granted'.
5
Check data layer
In browser console, type dataLayer and verify consent events are logged.
Common Issues
- No consent signal — Arqam360 script loads after Google tag. Fix: ensure Arqam360 loads first.
- Consent stuck on denied — Check if there's a JavaScript error preventing the consent update from firing.
- Only some parameters update — Verify your consent categories map correctly to GCM parameters.
- Tag Assistant shows 'Unknown' — Clear Tag Assistant cache and reconnect.
Tag Assistant is the definitive tool for debugging GCM v2. If consent signals look correct in Tag Assistant, the issue is likely in your Google Ads or GA4 configuration, not in Arqam360.
