Attribution and tracking
Affiliate link leakage and tracking loss
Publishers sometimes use “affiliate link leakage” or “EPC leakage” informally for possible loss of attributed revenue when links break, tracking parameters disappear, redirects fail or conversions are not credited. It is not a universally standardised metric.
What to check
Destination and redirect chain, tracking parameters where appropriate, and the programme's own reporting or test process.
Common misconception
An HTTP 200 response does not prove a sale will be attributed. A link checker shows redirects and visible parameters; it cannot guarantee commission tracking.
