google_ads_search_terms_analyze

Analyze keyword and search-term overlap plus N-gram distribution for a Google Ads campaign. Surfaces keyword candidates with conversions and high-cost, zero-conversion negative candidates.

Instructions

Analyze keyword/search-term overlap and N-gram distribution for a Google Ads campaign. Returns {campaign_id, period, registered_keywords_count, search_terms_count, overlap_rate (0.0-1.0), ngram_distribution:{unigrams, bigrams, trigrams} (each top-10 of {text, count, cost, conversions}), keyword_candidates:[{search_term, conversions, cost, clicks}] (CV>0 and not yet registered), negative_candidates:[{search_term, cost, clicks, impressions}] (top 20 by cost with cost>0 and conversions=0), insights:[strings]}. Read-only. For rule-scored add/exclude/watch buckets use google_ads_search_terms_review; for the raw unscored term log use google_ads_search_terms_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.
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
Behavior4/5

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

No annotations are provided, so the description carries the burden; it states 'Read-only' and then enumerates the full returned payload including derived semantics with thresholds (overlap_rate 0.0-1.0, keyword_candidates qualified by CV>0 and not yet registered, negative_candidates top 20 by cost with cost>0 and conversions=0), which discloses the tool's filtering logic. It does not mention permission/auth requirements or result-size limits for the n-gram lists beyond 'top-10', so it falls just short of full behavioral coverage.

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 and sibling routing are front-loaded, and the long return-shape enumeration earns its length because there is no output schema. It is dense with curly-brace structure, but no sentence is purely redundant; slightly heavy to parse as one block.

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?

With no output schema and no annotations, the description supplies the return contract (field names, ranges, candidate qualification rules) plus the read-only safety profile and the routing to alternatives. An agent has everything needed to call it and interpret the result.

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 documents the enum spellings, the explicit-range formats, and the LAST_90_DAYS time-zone asymmetry. The description adds nothing about parameters, so the baseline 3 for schema-does-the-work is correct.

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?

Starts with a specific verb-and-resource statement ('Analyze keyword/search-term overlap and N-gram distribution for a Google Ads campaign') and immediately names the two closest siblings and what they do instead, so an agent can disambiguate from google_ads_search_terms_review and google_ads_search_terms_report without opening a 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?

Explicitly routes: 'For rule-scored add/exclude/watch buckets use google_ads_search_terms_review; for the raw unscored term log use google_ads_search_terms_report.' That is a when-this vs when-that statement with named alternatives, exactly what selection needs.

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