AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill provides a structured approach to troubleshooting Google Ads account performance, such as conversion drops, lead flow issues, and lost impression share. It leverages the Google Ads MCP server tools to execute GAQL queries, enabling users to isolate the root causes of performance fluctuations. The skill includes specific workflows for analyzing traffic, conversion rates, impression share metrics, and offline conversion upload health, while providing guidance on handling API-specific constraints and data formatting.
What it does
- Identifies active client accounts for diagnostic targeting.
- Analyzes conversion and conversion value trends over specific date ranges.
- Diagnoses lost impression share due to budget or ad rank constraints.
- Investigates drops in lead flow by isolating traffic and conversion rate changes.
- Verifies the health of offline conversion upload pipelines.
- Provides GAQL query templates and guidance on handling API data gotchas.
When to use it
- When experiencing a sudden drop in conversion volume or value.
- When investigating why lead flow has decreased over a specific period.
- When analyzing lost impression share to determine if budget or bid adjustments are needed.
- When troubleshooting issues with offline conversion data imports.
- When needing to audit recent account changes that may have impacted performance.
Advantages
- Provides standardized GAQL query patterns for consistent diagnostics.
- Includes critical API constraints and data formatting tips to prevent common errors.
- Offers a clear, step-by-step methodology for isolating performance variables.
- Ensures safe interaction with Google Ads data by prioritizing authorized MCP tools.
Usage examples
- “Why did my conversions drop last week compared to the week before?”
- The agent will identify the account, run a comparative GAQL query for conversions and cost, and analyze the results to pinpoint if the drop is related to specific devices or conversion actions.
- “Check if my campaigns are losing impressions due to budget constraints.”
- The agent will query the campaign resource for search_budget_lost_impression_share and provide a summary of which campaigns are limited by budget.

Google Ads API Account Performance Diagnostics Skill
This skill provides instructions on how to use the Google Ads MCP server tools to diagnose common account performance issues.
Workflows
Pre-Flight Tool Verification
Before starting any diagnostic task, verify whether the Google Ads MCP Server tools (search, list_accessible_customers, get_resource_metadata — these may be exposed with a server prefix, e.g. customers_list_accessible_customers) are available in the runtime environment:
If MCP tools are available: Proceed with live diagnostics — first identify active client accounts, then run GAQL via the
searchtool (argumentscustomer_idandquery).If MCP tools are missing: Follow Fallback When MCP Tools Are Unavailable.
Identifying Active Client Accounts
Most diagnostics tasks require sending GAQL queries to a specific customer account. If the customer ID is not explicitly provided by the user, you must first call the list_accessible_customers (or customers_list_accessible_customers) tool to retrieve the customer resource names/IDs you have access to.
Once you have the list of accessible customer IDs, query the customer_client resource using the search tool under those customer accounts to find active client customer accounts. Make sure to select only enabled client accounts and filter out manager accounts:
SELECT
customer_client.id,
customer_client.descriptive_name,
customer_client.status,
customer_client.manager
FROM customer_client
WHERE customer_client.status = 'ENABLED' AND customer_client.manager = FALSEOnly run subsequent diagnostic queries against the enabled client customer IDs retrieved from this list. Do not query deactivated or manager accounts, as doing so will cause API errors.
Fallback When MCP Tools Are Unavailable
When Google Ads MCP tools (search, list_accessible_customers, get_resource_metadata — these may be exposed with a server prefix, e.g. customers_list_accessible_customers) are not registered in the runtime environment:
Inform the User: State that live account performance diagnostics require the Google Ads MCP Server.
Reference Setup Guide: Direct the user to the setup instructions in the google-ads-api-mcp-setup skill to install and configure the Google Ads MCP Server for their assistant environment.
Provide GAQL Templates, Gotchas, and Remediation Guidance: Formulate and output the complete diagnostic plan for manual execution in the Google Ads Query Builder or via API integration:
Provide all multi-step GAQL queries for the workflow, including current-vs-prior date window comparisons (e.g. traffic, impression share, conversion breakdowns, or change events).
Explain all metric conversion and constraint gotchas (
metrics.cost_micros / 1,000,000for currency, impression share reported as decimals or"< 0.10",change_event30-day window andLIMIT 10000withoutmetrics.*, andsuccessful_event_count / total_event_countplusstatusfor upload health).Outline concrete actionable next steps for each diagnostic branch (e.g., raising campaign budgets when
search_budget_lost_impression_shareis high vs. improving ad quality or bids whensearch_rank_lost_impression_shareis high).
Do Not Attempt Unauthorized Local Probing: Do not attempt to run shell commands, custom Python scripts, local SQL/database queries, or direct RPC CLI utilities to access account data. These commands lack credentials and API access and will fail.
1. Conversion and Conversion Value Loss
When conversions or conversion value suddenly decline, use the following steps to diagnose the issue.
Steps:
Discover Fields: Use
get_resource_metadatawith resourcecampaignorad_groupto ensure you have the correct field names.Query Performance: Use
searchto retrieve performance data.Resource:
campaignorad_groupFields: Include
campaign.name,metrics.conversions,metrics.conversions_value,metrics.cost_micros.Segments: To isolate the loss, include segments like
segments.date,segments.device,segments.conversion_action.Conditions: Compare the period of decline with a previous period (e.g.,
segments.date >= '{start_date}').Gotcha:
metrics.cost_microsmust be divided by 1,000,000 to get standard currency amounts.Gotcha (conversion action segmentation): In GAQL,
metrics.cost_microscannot be selected when segmenting bysegments.conversion_action. Query conversion action breakdowns separately withoutmetrics.cost_micros.
Example GAQL Queries:
To query performance and cost by date and device:
SELECT campaign.name, metrics.conversions, metrics.conversions_value, metrics.cost_micros, segments.date, segments.device FROM campaign WHERE segments.date >= '{start_date}' AND segments.date <= '{end_date}'To query conversion breakdown by conversion action (without
metrics.cost_micros):
SELECT campaign.name, metrics.conversions, metrics.conversions_value, segments.date, segments.conversion_action FROM campaign WHERE segments.date >= '{start_date}' AND segments.date <= '{end_date}'Analyze: Check if the loss is limited to certain devices (e.g., mobile vs desktop) or specific conversion actions.
Check Uploads: If using offline imports, query
offline_conversion_upload_conversion_action_summaryto verify upload pipeline health. If the query returns no results, report that no offline uploads exist for the account and proceed.Example GAQL Query: To check upload pipeline health for a customer account
{customer_id}:SELECT offline_conversion_upload_conversion_action_summary.conversion_action_name, offline_conversion_upload_conversion_action_summary.successful_event_count, offline_conversion_upload_conversion_action_summary.total_event_count, offline_conversion_upload_conversion_action_summary.status FROM offline_conversion_upload_conversion_action_summary
2. Opportunities Lost (Impression Share)
To identify lost opportunities due to ad rank, bids, or budgets, analyze impression share metrics.
Steps:
Query Impression Share: Use
searchto retrieve impression share metrics.Resource:
campaignFields: Include
campaign.name,metrics.search_impression_share,metrics.search_rank_lost_impression_share,metrics.search_budget_lost_impression_share.Gotcha: Impression share values in the API are returned as decimals (e.g., 0.35 = 35%) or formatted strings (e.g.,
"< 0.10").
Example GAQL Query: To query impression share metrics for a customer account
{customer_id}between{start_date}and{end_date}:SELECT campaign.name, metrics.search_impression_share, metrics.search_rank_lost_impression_share, metrics.search_budget_lost_impression_share FROM campaign WHERE segments.date >= '{start_date}' AND segments.date <= '{end_date}'Analyze:
High
search_budget_lost_impression_shareindicates opportunities lost due to limited budget.High
search_rank_lost_impression_shareindicates opportunities lost due to low ad rank (bid or quality issues).
3. Low Lead Flow Diagnostics
When a user asks "why is my lead flow low these past few days?", follow this systematic approach.
Steps:
Confirm Drop: Query conversions segmented by date for the last few days vs the previous period.
Isolate Cause:
Check if Traffic (clicks, impressions) dropped.
Check if Conversion Rate (conversions/clicks) dropped.
Example GAQL Query (Traffic and Conversion Trends): To query traffic and conversion rate metrics across campaigns segmented by date:
SELECT campaign.id, campaign.name, segments.date, metrics.impressions, metrics.clicks, metrics.ctr, metrics.conversions, metrics.conversions_from_interactions_rate FROM campaign WHERE segments.date >= '{start_date}' AND segments.date <= '{end_date}' ORDER BY segments.date DESCIf Traffic Dropped: Check Impression Share metrics (see Workflow 2) to see if it's a budget or rank issue, or if search volume generally declined.
If Conversion Rate Dropped: Check breakdowns by
segments.deviceorsegments.conversion_actionto see if a specific area is failing.Check Changes: Query the
change_eventresource to see if any changes were made to bids, budgets, or targeting around the time the drop started.Gotcha (change_event constraints): Queries to the
change_eventresource:Must specify a
LIMITclause of less than or equal to 10000.Must filter by date (
change_event.change_date_time) within the past 30 days.Cannot select performance metrics (e.g.,
metrics.*is not supported; onlychange_eventattributes and allowed resource fields can be selected).
Example GAQL Query: To query change events for a customer account
{customer_id}between{start_date}and{end_date}:SELECT change_event.change_date_time, change_event.change_resource_name, change_event.resource_change_operation, change_event.changed_fields FROM change_event WHERE change_event.change_date_time >= '{start_date}' AND change_event.change_date_time <= '{end_date}' LIMIT 10000
4. Offline Upload Pipeline Diagnostics
When offline conversion uploads for a specific action (e.g., store-purchase) stop showing up or fail, use the following steps to diagnose the issue.
Steps:
Retrieve Client Accounts: If
{customer_id}is not provided, follow Identifying Active Client Accounts to retrieve active client customer accounts.Verify Pipeline Health: Query
offline_conversion_upload_conversion_action_summaryfor the active client account.Fields: Include
offline_conversion_upload_conversion_action_summary.conversion_action_name,offline_conversion_upload_conversion_action_summary.successful_event_count,offline_conversion_upload_conversion_action_summary.total_event_count, andoffline_conversion_upload_conversion_action_summary.status.
Example GAQL Query:
SELECT offline_conversion_upload_conversion_action_summary.conversion_action_name, offline_conversion_upload_conversion_action_summary.successful_event_count, offline_conversion_upload_conversion_action_summary.total_event_count, offline_conversion_upload_conversion_action_summary.status FROM offline_conversion_upload_conversion_action_summaryAnalyze:
Gotcha: If the query to
offline_conversion_upload_conversion_action_summaryreturns no results or is empty (indicating there are no offline conversion uploads configured or active for the customer account), immediately stop/break the diagnostic workflow. Report directly to the user that no offline conversion upload data or summaries exist in the accessible account(s), rather than retrying or attempting to generate custom scripts.If results are returned, verify the upload success rate by comparing
successful_event_countwithtotal_event_count. Check thestatusfield to diagnose failures.
