Unlike other awards, such as the Grammy Award, which determine nominations as a result of the highest votes received by the National Academy of Recording Arts and Sciences, the Billboard Music Awards finalists are based on album and digital songs sales, streaming, radio airplay, touring, and social engagement. These measurements are tracked year-round by Billboard and its data partners, including
Nielsen Music and Next Big Sound. The 2018 awards are based on the reporting period of April 8, 2017 through March 31, 2018. Awards are given for the top album, artist and single in a number of different music genres.
