This work marked a true commercial takeoff for Bocelli, reaching the top positions on the charts in Europe and Latin America. Sales exceeded 20 million copies worldwide, consolidating him as one of the best-selling albums in Italian and predominantly in other languages in history. Songs like Con Te Partirò and Vivo Per Lei resonated especially, the latter with versions recorded alongside artists of different nationalities such as Hélène Ségara in France, Marta Sánchez in Spain, and Judy Weiss in Germany, each with its own music video. Promotion in the United States included his appearance in commercials for the Bellagio Hotel and his participation in the PBS special A Night in Tuscany.
The impact of Romanza extended throughout 1997 with an intense schedule of performances and recognitions. Bocelli performed at significant events such as the Puccini Festival in Italy and for Pope John Paul II in Paris. In Germany, he received three ECHO awards and a Bambi, celebrating both the album and previous singles. The support tour in Germany included numerous open-air and indoor concerts, covering cities such as Berlin, Hamburg, and Cologne. In the United Kingdom, he performed a concert with Sarah Brightman at the Royal Albert Hall in London, and in Italy, he sang again for the Pope in Bologna and participated in the TeleFood charity concert in the Vatican City.
