Audit campaign landing-page quality in GA4 with Claude

Write a one-page operating charter for campaign landing-page quality and downstream conversion behavior before exporting any data. State the exact decision this workflow supports: which landing pages need message, UX, targeting, or tracking changes. Define the in-scope business units, pipelines, regions, date window, record types, and exclusions, then name one analysis owner, one Google Analytics 4 data owner, and one final approver. Record the review cadence as weekly during active campaigns and specify where evidence, approvals, and exceptions will be stored. Review the charter with the approver and do not proceed until the scope and decision rights are accepted.

Convert the operating policy into a rule register that can be checked against GA4 events and dimensions. Create one row per rule with rule_id, rule_name, business_reason, required_fields, calculation_or_test, pass_condition, exception_code, severity, owner, and policy_version. Start with these minimum checks: UTM values are normalized, landing-page cohorts use the same date window, campaign traffic is not mixed with unrelated organic sessions, CTA and form events fire once per intended action, and low-volume pages are not ranked as winners prematurely. Give every rule an example that should pass and an example that should fail so reviewers interpret it consistently. Have the business owner approve the rule register and record any unresolved policy questions before data is scored.
