Skill 062: Audience Minimum Size Monitoring

Purpose

Monitor remarketing and customer lists to ensure they maintain the minimum 1,000+ members required for Search targeting. Audiences below threshold cannot be used for targeting and may affect campaign delivery.

Data Requirements

Data Source: Custom GAQL Required

The standard export does not include user list size data.

Standard Data:

• data/account/campaigns/*/audience_targeting.md - Audience usage in campaigns

GAQL Query:

SELECT
  user_list.id,
  user_list.name,
  user_list.type,
  user_list.size_for_search,
  user_list.size_for_display,
  user_list.membership_status,
  user_list.membership_life_span,
  user_list.eligible_for_search,
  user_list.eligible_for_display
FROM user_list
WHERE user_list.membership_status = 'OPEN'

Run via /google-ads:get-custom with query name audience_sizes.

Analysis Steps

1. Fetch all audience lists: Run custom GAQL to get list sizes and eligibility status.
2. Categorize by size status: Healthy (5,000+), Acceptable (1,000-5,000), At Risk (500-999), Below Minimum (<500).
3. Cross-reference with campaigns: Identify if undersized lists are used in targeting (vs observation).
4. Flag critical issues: Audiences below minimum that are actively used for targeting.

Thresholds

Condition	Severity
Search audience < 500 users	Critical
Audience used for targeting but ineligible	Critical
Search audience 500-999 users	Warning
Display audience < 100 users	Warning
Audience trending down >20% weekly	Warning
