We work closely with a number of services for the creation of smart links.
Linkfire is one tool and provides a great splash page for your releases. The link itself will point people towards a splash page that includes the top digital services for fans. You must request an account with Linkfire, as we can’t help with account setup. Click here for an example - http://awal.lnk.to/9M7KG
Smart URLs are smart links that are most effective with iTunes / Apple. You can sign up for free, generate your own smart links ad, and then access the analytics. Its primary use is to make sure the link will work seamlessly in all territories. You can choose whether the link prefers Apple music or iTunes which is also useful.
