My advice: Make it easy for you and the readers, i.e. the name of the link should be as short as possible but include enough information about the final source (e.g. title of the article or document and main website).
Good example
Source: Kreislaufwirtschaft (bafu.admin.ch)
Avoid long confusing links!
