Google Analytics (GA4) Analyst

Analyzes GA4 traffic, acquisition, landing pages, events and conversions through the NotFair MCP connector, and safely handles key-event or custom-dimension changes.

Data & AnalyticsIntermediate★ 3,872⑂ 496AI score 8/10Last updated: Sep 25, 2026

What it does

  • Resolves the exact GA4 property (properties/123456789) from the live connector and refuses to substitute a G- measurement ID or account ID.
  • Pulls the smallest decision-grade report set across channel, source/medium, campaign, landing page, device, geography, and events, always with absolute values plus deltas.
  • Checks response metadata for sampling, thresholding, quota warnings, collapsed (other) rows, provisional intraday data, and property timezone.
  • Keeps GA4 attribution separate from ad-platform attribution and explains discrepancies instead of blending numbers; blocks unsupported causal claims.
  • For measurement config changes, shows current state, proposed state, reporting impact, and rollback path before requesting approval.

Who it's for

  • Marketers and growth teams building weekly/monthly GA4 performance reports.
  • Site owners diagnosing sudden traffic or conversion drops.
  • Data/analytics practitioners maintaining measurement configuration across properties.

Examples

  1. "Compare the last 4 weeks vs. the prior 4 weeks and find why organic sessions fell 30%, by channel and landing page."
  2. "Build a top-converting campaign table for this month vs. last month and flag any sampling."
  3. "Before marking purchase_complete as a key event, summarize reporting impact and how to roll it back."

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the analytics/google-analytics folder from the GitHub repo nowork-studio/notfair-plugin into my ~/.claude/skills/google-analytics/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/nowork-studio/notfair-plugin.git && mkdir -p ~/.claude/skills/google-analytics && cp -r notfair-plugin/analytics/google-analytics/* notfair-plugin/analytics/shared ~/.claude/skills/google-analytics/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Clone the repository: git clone https://github.com/nowork-studio/notfair-plugin.git
  2. Create the skill folder: mkdir -p ~/.claude/skills/google-analytics
  3. Copy the skill plus its shared contract file: cp -r notfair-plugin/analytics/google-analytics/* notfair-plugin/analytics/shared ~/.claude/skills/google-analytics/
  4. Connect your Google Analytics account in the NotFair plugin (MCP connector) and verify access to the target GA4 property.
  5. Restart Claude Code and try: "Show GA4 sessions by channel for the last 30 days."
  6. For configuration changes, read the approval step carefully — archiving a custom dimension is irreversible and its parameter name cannot be reused.
