Campaign Tracking QA Checker — illustrative example

INPUT
Approved tracking: utm_medium=email. Supplied URL: https://example.com/report?format=csv&utm_medium=EmailNewsletter&utm_campaign=october.

RESULT
Finding: utm_medium uses EmailNewsletter instead of the approved email value.
Corrected URL: https://example.com/report?format=csv&utm_medium=email&utm_campaign=october
Preserved: destination path, functional format=csv parameter and campaign name.

REVIEW
Validate tracking against a written specification. A syntactically valid URL can still send traffic into the wrong reporting category.

This is a teaching example, not a live execution record.
