Channel Links was a previously supported feature that was officially removed as of March 2020.
Why were Channel Links removed?
Vevo no longer supports channel links as the focus on landing pages for artists has been shifted to Official Artist Channels (OACs). Existing links will remain in place but can be removed if requested.
I'm an artist but don't have an OAC
Vevo does not assist in the creation of OACs. Please contact YouTube Artist Support.
Channel Links for Brand Channels
Since brand channels do not have OACs, Vevo will update these upon request. Submit a request with the proper details.
