A useful distinction
Two links can lead to the same product while having different referral arrangements. A reader needs relevant information about the publisher’s relationship, not merely a technical description of the URL. An ordinary source link is a different editorial role.
Put it into practice
Keep source references and compensated recommendations identifiable in the publishing plan. Check the actual relationship before writing a disclosure. This journal’s external references are educational source links and do not claim that the publication participates in the programmes being discussed.
