google_ads_budget_efficiency
Score budget allocation efficiency across enabled Google Ads campaigns. Identify efficient and inefficient campaigns and get actionable recommendations to optimize spend.
Instructions
Score budget allocation efficiency across every ENABLED Google Ads campaign. Returns {period, total_cost, total_conversions, campaigns:[{campaign_id, name, cost, conversions, cost_share, cv_share, efficiency_ratio (cv_share / cost_share), verdict ('EFFICIENT' when ratio > 1.2, 'INEFFICIENT' when < 0.8, 'NORMAL' otherwise, 'NO_COST' when cost==0), cpa}], recommendations:[strings], insights:[strings]}. Per-campaign cost/conversions come from get_performance_report — individual failures are silently treated as zero. Read-only. For a concrete DECREASE/INCREASE reallocation plan use google_ads_budget_reallocation; to change a single budget use google_ads_budget_update.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| period | No | Reporting window for the metrics. Default 'LAST_30_DAYS'. Use a shorter window (LAST_7_DAYS / LAST_14_DAYS) when diagnosing recent changes; use LAST_90_DAYS for trend baselines. Also accepts an explicit range in GAQL spelling — "BETWEEN 'YYYY-MM-DD' AND 'YYYY-MM-DD'", both endpoints inclusive, in the account's time zone — for a window no trailing constant can reach (e.g. a single past calendar month). One asymmetry to know about: every constant except LAST_90_DAYS is resolved by Google Ads in the account's reporting time zone, whereas LAST_90_DAYS has no API constant and is expanded by mureo into the 90 days ending yesterday **on the server's date**, so its edges can differ by a day when the server and the account are in different zones. Pass an explicit range when the exact boundary matters. | |
| 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. |
