google_ads_rsa_assets_analyze
Split Responsive Search Ad metrics by headline and description to compare asset impressions, clicks, conversions, cost, and CTR and surface optimization insights.
Instructions
Split Responsive Search Ad asset performance within a Google Ads campaign into headlines and descriptions. Returns {campaign_id, period, headlines:[{text, performance_label ('BEST'|'GOOD'|'LOW'|'POOR'|'LEARNING'|'PENDING'|'UNKNOWN'), impressions, clicks, conversions, cost, ctr (percent)}], descriptions (same shape), best_headlines (performance_label == 'BEST'), worst_headlines ('LOW'|'POOR'), best_descriptions, worst_descriptions, insights:[strings]}. Rows sorted by impressions descending. Read-only. For an audit version with replacement recommendations use google_ads_rsa_assets_audit; for ad-level A/B use google_ads_ad_performance_compare.
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 — "YYYY-MM-DD..YYYY-MM-DD" (the spelling Meta Ads takes too) or, 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. | |
| campaign_id | Yes | Campaign ID as a numeric string without dashes (e.g. '23743184133'). Obtain via google_ads_campaigns_list. | |
| 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. |
