google_ads_auction_insights_get

Fetch raw impression-share metrics for one Google Ads campaign to see how much search impression share is lost to rank or budget, plus top-of-page rates.

Instructions

Fetch raw impression-share metrics for one Google Ads campaign. Returns a list with a single entry: {campaign_id, campaign_name, search_impression_share, search_rank_lost_is, search_budget_lost_is, search_top_is, search_abs_top_is, note} — every IS field is a percentage (0-100, float, rounded to 1 decimal) or None. On failure returns a single-element list with {error:'auction_insights_unavailable'|'no_data', reason, hint}. Read-only. Note: Google Ads API v23 removed competitor-level auction_insight (domain, overlap, outranking); only impression-share proxies are returned. For a version with human-readable insights layered on top use google_ads_auction_insights_analyze.

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.
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

A4.4/5.0
Behavior5/5

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

With no annotations, the description carries the full burden and does so well: it declares read-only, documents the exact returned field set and units ('every IS field is a percentage (0-100, float, rounded to 1 decimal) or None'), and enumerates failure behavior with concrete error codes ('auction_insights_unavailable'|'no_data') plus reason/hint. The Google Ads API v23 caveat that competitor-level auction_insight was removed explains why the payload is a proxy, preventing an agent from misinterpreting missing competitor data.

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

Conciseness4/5

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

Purpose is front-loaded in the first clause, followed by return shape, then failure shape, then the version caveat and the sibling hand-off — a clean information order with no filler. It is dense (one long block, a run-on list of fields) rather than wasteful, so not quite a 5.

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?

There is no output schema, so the description must explain returns and it does so completely: success payload fields, null semantics, percentage scaling, and the error payload shape. Combined with the version caveat and alternative-tool pointer, an agent has everything needed to call and interpret it.

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?

Schema description coverage is 100% and the period parameter already carries extensive guidance (constants, explicit range spellings, time-zone asymmetry), so the schema does the heavy lifting. The description adds only the implicit notion of 'one campaign' and does not explain campaign_id/customer_id semantics beyond what the schema states; baseline 3 applies.

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 ('Fetch raw impression-share metrics for one Google Ads campaign') and scopes it to a single campaign, which distinguishes it from the broader performance/report siblings. The final sentence explicitly separates it from google_ads_auction_insights_analyze, so an agent can route correctly without opening either schema.

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

Usage Guidelines4/5

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

Names the alternative explicitly ('For a version with human-readable insights layered on top use google_ads_auction_insights_analyze'), giving a clear selection rule. It doesn't state when this raw variant is the better choice versus the analyze variant beyond that implication, so it falls short of full when/when-not coverage.

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