Google Analytics (GA4) Analysis Skill

Analyzes GA4 traffic, acquisition, engagement, and conversions via the NotFair MCP connector, and safely manages key events and custom dimensions.

Data & AnalyticsIntermediate★ 3,354⑂ 418AI score 8/10Last updated: Aug 13, 2026

What it does

  • Resolves the exact GA4 property resource and pins down the business question, primary metric, timezone, date range, and comparison window before pulling data.
  • Fans out only the smallest useful set of reports across channel, source/medium, campaign, landing page, device, geography, and events to explain what changed.
  • Flags sampling, thresholding, quota warnings, collapsed (other) rows, and provisional intraday data instead of presenting them as clean numbers.
  • Keeps GA4 attribution separate from ad-platform attribution and explains discrepancies rather than blending them.
  • Restricts configuration changes to dedicated mutation tools, showing current state, proposed state, reporting impact, and rollback before requesting approval — with an explicit gate on irreversible custom-dimension archiving.

Who it's for

  • Growth and marketing teams who read GA4 reports weekly
  • Analysts diagnosing traffic or conversion drops with reproducible evidence
  • GA4 admins who want guardrails around measurement configuration changes

Example uses

  1. "Organic conversions dropped 30% last week — compare by channel and landing page and tell me the likely driver."
  2. "Build a campaign-level revenue and conversion-rate table for this month vs. the same period last month."
  3. "Before I register purchase as a key event, show me the downstream reporting impact and rollback path."
