Performing during the show in position 5, "Higher Ground" was announced among the top 10 entries of the second semi-final and therefore qualified to compete in the final on 12 May.

Along with their participation confirmation, the broadcaster announced that Dansk Melodi Grand Prix 2018 would be organised in order to select Denmark's entry for the 2018 contest.

The event was held on 10 February 2018 at the Gigantium in Aalborg, hosted by Annette Heick and Johannes Nymark and televised on DR1 as well as streamed online at DR TV.

The five-member jury panel was composed of five Danish Eurovision fans: Julie Lund Mikkelsen, Jens Erik Møller, Morten Madsen, Christian Kaad and Anna Bennike.

[2] Mads Enggaard, who was appointed as the new music producer of Dansk Melodi Grand Prix, stated that the competition would seek out "songs that are inspiring and create pictures and arouse emotions".

[9] DR held a press meet and greet at the Koncerthuset in Copenhagen on 22 January 2018 where the competing artists and songs were announced and officially presented.

[14] Rasmussen made several appearances across Europe to specifically promote "Higher Ground" as the Danish Eurovision entry.

[16] On 14 April, Rasmussen performed during the Eurovision in Concert event which was held at the AFAS Live venue in Amsterdam, Netherlands and hosted by Edsilia Rombley and Cornald Maas.

On 29 January 2018, a special allocation draw was held which placed each country into one of the two semi-finals, as well as which half of the show they would perform in.

[23][24] Following technical rehearsals, the Danish delegation requested a harsher snowfall effect as the snow provided by the Portuguese broadcaster was too light and fluffy for the song.

[25] The four backing vocalists that joined Rasmussen on stage were: Daniel Firth, Gustav Emil Bresler, Jesper Paasch and Mads Engelhardt.

Each nation's jury consisted of five music industry professionals who are citizens of the country they represent, with their names published before the contest to ensure transparency.

This jury judged each entry based on: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.

The individual rankings of each jury member as well as the nation's televoting results were released shortly after the grand final.
