On Spotify, there are two types of unique link for every artist profile:
an artist URI (Uniform Resource Indicator)
an artist web link (that can be pasted into an address bar)
On Apple Music, there is just one type of unique link for every artist profile:
an artist web link (that can be pasted into an address bar)
Adding a specific part of your Spotify Artist URI and your Apply Music artist web link to your release before you distribute it will ensure it is delivered to the correct artist profile.
The following instructions will guide you to finding these links. Bear in mind that they are for desktop - on mobile, they may vary.
