Instructions
Evaluate a Google Ads campaign's last-7-days CPA against a user-supplied target and integrate cost-increase analysis. Returns {campaign_id, target_cpa, current_cpa (float or None when conversions==0), cost_analysis (full google_ads_cost_increase_investigate payload), wasteful_terms (top 5 zero-CV cost terms from cost_analysis), deviation_pct, status ('healthy' when current<=target, 'warning' when <=target1.2 or when CV==0, 'critical' when >target1.2), issues:[strings], summary, suggested_workflow?}. The CPA window is hardcoded to LAST_7_DAYS. Read-only; does not change bids. For account-wide rollup use google_ads_health_check_all; for daily CV-count vs target use google_ads_monitoring_cv_goal.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| customer_id | No | Google Ads customer ID as a 10-digit string without dashes (e.g. '1234567890'). Optional — falls back to GOOGLE_ADS_CUSTOMER_ID / GOOGLE_ADS_LOGIN_CUSTOMER_ID from the configured credentials when omitted. | |
| campaign_id | Yes | Campaign ID as a numeric string without dashes (e.g. '23743184133'). Obtain via google_ads_campaigns_list. | |
| target_cpa | Yes | Target cost per acquisition in account currency (e.g. 3000 = ¥3,000). Required — this tool does NOT fall back to bidding-strategy or actual CPA. 'warning' threshold is target_cpa * 1.2; above that is 'critical'. |
