google_ads_ad_performance_report

Analyze individual ad performance in Google Ads by retrieving metrics like impressions, clicks, cost, and conversions, filterable by ad group or campaign.

Instructions

Report per-ad performance across Google Ads ad_group_ad rows. Returns one row per ad shaped as {ad_id, ad_type, status ('ENABLED'|'PAUSED'|'REMOVED'), ad_group_id, ad_group_name, campaign_id, campaign_name, metrics} where metrics contains impressions, clicks, cost_micros, cost (currency), conversions, ctr, average_cpc_micros, average_cpc, cost_per_conversion_micros, cost_per_conversion. Filterable by ad_group_id and/or campaign_id (both optional, both numeric). Read-only; no mutation. For ENABLED-only A/B comparison within a single ad group with WINNER/LOSER verdicts use google_ads_ad_performance_compare; for campaign-level aggregates use google_ads_performance_report.

Input Schema

NameRequiredDescriptionDefault
periodNoReporting 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.
ad_group_idNoOptional ad group ID as a numeric string (e.g. '145680123456') to restrict results to a single ad group. Omit to include every ad group matching the campaign filter.
campaign_idNoOptional campaign ID as a numeric string (e.g. '23743184133') to restrict the report to a single campaign. Omit to aggregate across every campaign in the account.
customer_idNoGoogle 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.

TDQS

A4.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden and does so well: it declares 'Read-only; no mutation', discloses the exact result row shape including the status enum, and specifies the filter grain. It does not mention pagination, row limits, or response size behavior for large accounts, which is the remaining gap for an unbounded report tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the output grain and shape, then filters, then the safety statement, then sibling routing — a sensible priority order with no filler sentences; the dense return-shape sentence earns its length because there is no output schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, so the inline row contract ({ad_id, ad_type, status, ad_group_id, ... metrics with ctr, cost, cost_per_conversion}) is exactly the missing piece an agent needs, and the filtering and read-only semantics complete the picture.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3; the description adds genuine value by saying the two ID filters are 'both optional' and combinable ('and/or', 'both numeric'), which the per-parameter schema text does not state about their interaction. It adds nothing to the period parameter, which the schema already documents in depth.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Report per-ad performance across Google Ads ad_group_ad rows'), pins the grain ('one row per ad'), and explicitly distinguishes itself from google_ads_ad_performance_compare and google_ads_performance_report. An agent can select it without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Names two alternatives with the exact condition that selects each: ENABLED-only A/B comparison in a single ad group goes to ad_performance_compare, campaign-level aggregates go to google_ads_performance_report. It also gives when-to-use for the period filter (short windows for recent change diagnosis, LAST_90_DAYS for trend baselines).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
