Description

🚨 **IF THIS TOOL RETURNS A QUOTA ERROR:** - The error message will include a clickable upgrade link - Show the FULL error message to the user (it contains the upgrade link) - DO NOT attempt to work around the error or use alternative data - DO NOT create campaigns or perform actions without valid tool data - STOP and direct the user to upgrade via the provided link Read Google's own per-asset performance_label for every image in a PMax campaign, plus asset-group-level rollup metrics. PMax does not expose per-image CTR / conversions on Google's side — Google instead publishes its own ML grade per asset: BEST / GOOD / LOW / LEARNING / PENDING. This tool surfaces that label directly, and adds a derived `recommended_action`: - LOW → REPLACE - LEARNING / PENDING → WAIT - GOOD / BEST → KEEP - UNKNOWN / UNSPECIFIED → REVIEW Per-group metrics (impressions, clicks, conversions, cost_micros, CTR, CVR) are rolled up for the requested date range. Labels themselves are not date-scoped on Google's API; they reflect Google's current grade. **Use when:** - Identifying which assets to swap during a monthly creative refresh - Sanity-checking that newly added assets have left LEARNING - Reporting on PMax creative health per asset group **Parameters:** - campaign_id: The PMax campaign ID - asset_group_id: optional — scope to one group - date_range / start_date+end_date: window for the group-level metrics - min_label_severity: optional filter (LOW / GOOD / BEST) **Execution time:** 2-5 seconds (two GAQL queries)
