Deezer has had an option similar to Spotify for Artists: Deezer Backstage since early 2020. Just like with Spotify for Artists, Deezer Backstage allows you to supplement your profile with photos, a biography and links to your social media accounts. In addition, Deezer also promises that you will gain more insight into the listening behavior of your fans.
You can register for Deezer Backstage via https://backstage.deezer.com/user/login.
You have the choice to register as an artist, label or manager. For your registration you need, among other things, a UPC for one of your releases and you also have to provide the name and email address of your distributor. You can also enter links for your profiles on Facebook, Instagram and Twitter, but these are not mandatory.
