Songwriters that were interested in entering the Swiss national final had the opportunity to apply during a submission period organised by SRG SSR.

Performing during the show in position 17, "Stones" was not announced among the top 10 entries of the second semi-final and therefore did not qualify to compete in the final.

Their second and, to this point, most recent victory was achieved in 1988 when Canadian singer Céline Dion won the contest with the song "Ne partez pas sans moi".

In 2005, the internal selection of Estonian girl band Vanilla Ninja, performing the song "Cool Vibes", qualified Switzerland to the final where they placed 8th.

[13] On 14 April, Zibbz 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.

[16] According to Eurovision rules, all nations with the exceptions of the host country and the "Big Five" (France, Germany, Italy, Spain and the United Kingdom) are required to qualify from one of two semi-finals in order to compete for the final; the top ten countries from each semi-final progress to the final.

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] The Swiss performance featured the members of Zibbz performing on stage; Corinne Gfeller wore a short top with strings, skinny jeans and a maroon hat while Stee Gfeller wore a leather jacket with a white shirt underneath.

[24][25] Zibbz was joined by three off-stage backing vocalists: the co-composer of "Stones" Laurell Barker, Nita Fernandes and Sabrina Kern.

[26] At the end of the show, Switzerland was not announced among the top 10 entries in the first semi-final and therefore failed to qualify to compete in the final.

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.

In addition, no member of a national jury was permitted to be related in any way to any of the competing acts in such a way that they cannot vote impartially and independently.

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