- Teams with sudden Direct or Unassigned growth
- Organizations comparing first-touch and session-scoped acquisition
- Marketers managing several paid and partner channels
Compare session and first-user acquisition, default channel groups, attribution paths, UTMs, referrals, and key events to detect classification shifts before reports mislead budget decisions.
A channel-anomaly register, likely root causes, reporting caveats, and a recurring attribution monitoring routine.

Why this works
Channel reports can move because user behavior changed, but they can also move because UTMs, channel rules, referral exclusions, consent, or key-event configuration changed. GA4 separates first-user acquisition from session acquisition and provides attribution-model and path views, which makes scope errors visible when the data is compared deliberately. Claude can detect discontinuities and reconcile evidence across exports without declaring causality from correlation alone. A recurring monitor catches measurement drift before it becomes a budget narrative.
Expected results
Records or configurations reviewed
100% of the approved in-scope population
The run reconciles every eligible record or configuration item to the signed source manifest rather than relying on an informal sample.
Evidence validation
Stratified QA before action
Every major finding class and high-impact segment is checked against source records before operational changes are approved.
Decision output
One owner-ready action register
Findings are converted into deduplicated actions with evidence, confidence, owners, approvers, deadlines, and rollback requirements.
Operational reuse
Versioned recurring runbook and Claude Skill
The same inputs, rules, prompts, schemas, validation gates, and metrics can be rerun while preserving a visible change history.

30-60 min
30-60 min
Define expected weekly share and variance for default channel group, session source/medium, first-user source/medium, direct, unassigned, and key-event attribution. The controls below apply throughout the workflow, not only to this step.
Set channel baselines and alert thresholds completed as a dated section of the attribution anomaly watchlist, with session source, channel share variance, evidence links, owner, and approval status for repair UTMs.
Do not let session source stand in for session medium; that shortcut creates false positives in channel attribution anomaly. Document the result in the same run folder so the next cycle can compare like with like. Apply it specifically during “Set channel baselines and alert thresholds.”
30-60 min
30-60 min
Document UTMs, auto-tagging, gclid capture, cross-domain settings, referral exclusions, consent mode, offline imports, channel-group rules, and recent configuration changes.
Inventory attribution dependencies completed as a dated section of the attribution anomaly watchlist, with session medium, direct-traffic inflation, evidence links, owner, and approval status for exclude rogue referrals.
Keep seasonality visible as its own class because merging it into the main failure rate will distort the decision. Document the result in the same run folder so the next cycle can compare like with like. Apply it specifically during “Inventory attribution dependencies.”
