google_ads_auction_insights_analyze

Interpret impression-share metrics to uncover competitive position and get actionable insights. Identifies low impression share, budget/rank losses, and top-of-page gaps for a campaign.

Instructions

Interpret a campaign's impression-share metrics and surface human-readable insights about competitive position. Returns {campaign_id, campaign_name, period, impression_share_metrics:{search_impression_share, search_rank_lost_is, search_budget_lost_is, search_top_is, search_abs_top_is, note}, insights:[strings], note}. Each impression-share value is a percentage (0-100, rounded to 1 decimal) or None. Insights fire when IS < 50/70%, rank-lost > 20%, budget-lost > 20%, or abs-top-IS < 20%. Read-only. Note: Google Ads API v23 removed competitor-level auction_insight (domain overlap, outranking share); only impression-share proxies are returned. For the raw metrics without insights use google_ads_auction_insights_get; full competitor data is only available in the Google Ads UI.

Input Schema

TableJSON 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 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_idYesCampaign ID as a numeric string without dashes (e.g. '23743184133'). Obtain via google_ads_campaigns_list.
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
Behavior5/5

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

With no annotations provided, the description carries the full burden and does so thoroughly. It explicitly states the tool is read-only, describes the exact return structure including nullable values, lists the insight thresholds, and discloses the Google Ads API v23 limitation regarding competitor-level auction insight data.

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?

The description is front-loaded with the tool's core purpose and return shape, then adds thresholds, read-only status, an API limitation note, and the alternative tool. Every sentence adds distinct value; there is no filler or repetition.

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?

The tool has no output schema, yet the description fully defines the returned object, its fields, types, thresholds, and the note about missing competitor data. Combined with the rich parameter descriptions in the schema, an agent has everything needed to select and invoke this tool correctly.

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

Parameters3/5

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

The schema already documents all three parameters with 100% coverage, including detailed guidance on period constants and explicit ranges. The description adds little parameter-specific meaning beyond that, but it does not need to because the schema carries the load.

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?

The description opens with a specific verb ('Interpret') and a clear resource ('a campaign's impression-share metrics'), then states it surfaces human-readable insights about competitive position. It also distinguishes itself from the sibling google_ads_auction_insights_get by explicitly saying that tool returns raw metrics without insights.

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?

The description gives explicit routing guidance: use google_ads_auction_insights_get for raw metrics without insights, and notes full competitor data is only available in the Google Ads UI. It also names the exact conditions under which insights fire, so an agent knows when this tool is appropriate.

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