Ariaudo joined Juventus as a nine-year-old and was part of the 2009 Torneo di Viareggio-winning team. He made his first team debut in Juventus's 1–1 draw with Artmedia Petržalka in the second leg of the 2008–09 UEFA Champions League third qualifying round, in which Juventus won 5–1 on aggregate to advance to the group stages, and was awarded a five-year professional contract. He made Serie A debut on 18 January 2009 against Lazio in Rome on a match that ended with a 1–1 draw. Although he was not able to break into the first team permanently that season, then-manager Ciro Ferrara described Ariaudo as a future prospect.
After being included in pre-season friendlies, Ariaudo was promoted to the first team permanently. On 2 January 2010, he was sent on loan to Cagliari for €500,000. After being on the bench for a string of games, he finally made his debut for the Sardinian club on 21 February as a starter and helped keep a clean sheet in a 2–0 win over Parma.
In June 2010, Cagliari excised the rights to purchase him in co-ownership deal for €1.3million. On 31 January 2011, the club purchased him outright, as part of the deal of Alessandro Matri's €2.5million loan.
In January 2016 he was signed by Empoli F.C..
On 25 March 2009 Ariaudo made his debut for the Italy Under-21 squad and marked it with a goal in the friendly game against Austria that ended with a 2–2 draw.  He was named in the preliminary squad for the 2009 European Championships but did not make the final 23-man squad. Since then, he has become a regular starter for the Azzurrini in their 2011 European Championship qualifying campaign, playing the full 90 minutes in four of the last five matches since March.
