Account Performance Diagnostics Skill
This skill provides instructions on how to use the Google Ads MCP server to diagnose common account performance issues.
Workflows
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_group - Fields: Include
campaign.name,metrics.conversions,metrics.conversion_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 >= 'YYYY-MM-DD').
- Resource:
- Analyze: Check if the loss is limited to certain devices (e.g., mobile vs desktop) or specific conversion actions.
- Check Uploads: If using offline conversions, consider checking
offline_conversion_upload_conversion_action_summaryfor upload issues.
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:
campaign - Fields:
campaign.name,metrics.search_impression_share,metrics.search_rank_lost_impression_share,metrics.search_budget_lost_impression_share.
- Resource:
- 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).
- High
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.
- If 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.- Note: Queries to
change_eventmust specify a LIMIT of less than or equal to 10000.
- Note: Queries to
