Skill 105: GA4 Advanced Audience Creation

Purpose

Audit GA4 behavioral audiences synced to Google Ads. GA4 enables targeting depth impossible with Google Ads alone, with behavioral audiences converting 50-100% better than page-view lists.

Data Requirements

Data Source: Standard + Custom GAQL

Standard Data:

• data/account/account_summary.md - GA4 linkage status
• data/account/campaigns/*/audience_targeting.md - Audience usage

Reference GAQL:

SELECT
  user_list.name,
  user_list.type,
  user_list.size_for_display,
  user_list.size_for_search
FROM user_list
WHERE user_list.type IN ('RULE_BASED', 'LOGICAL')

Use /google-ads:get-custom for audience inventory.

Note: Full GA4 audience audit requires GA4 property access.

Analysis Steps

1. Verify GA4 Linkage: Check if GA4 property is linked with bidirectional sharing
2. Inventory GA4 Audiences: Identify audiences originating from GA4
3. Categorize Audience Types: Basic, engagement-based, behavior-based, predictive
4. Identify Gaps: Missing high-value audiences (engaged users, pricing viewers)

Thresholds

Condition	Severity
No GA4 linked to Google Ads	Critical
GA4 linked but no audiences imported	Warning
No engagement-based audiences	Warning
No pricing/demo page visitor audience	Warning
Predictive audiences not enabled (if eligible)	Info

Output

Short (default):

## GA4 Audience Audit
**Account:** [name] | **GA4 Linked:** [Yes/No] | **GA4 Audiences:** [count] | **Issues:** [count]

### Critical
- **GA4 not linked** - Cannot import behavioral audiences

### Warnings
- **No engagement-based audiences** - Create 3+ sessions audience
- **No pricing page visitors** - High-intent segment missing

### Recommendations
1. Link GA4 with bidirectional data sharing
2. Create "High Engagement" audience (3+ sessions, 3+ min)
3. Create "Pricing Page Visitors" audience (14-day window)

Detailed adds:

• GA4 audience inventory table
• Recommended audiences by type (engagement, behavior, funnel stage)
• Predictive audience eligibility check
