Gio Compario is a fictional tenor who has been the mascot of since 2009. In each advert he has been in, he sings a song about the website to the tune of Over There.

In 2012, new adverts were launched featuring Gio being attacked by various celebrities who wanted to "save the nation" from his annoying singing. Gio was removed from the adverts in 2014 and the adverts instead showed the residents of a fictional Welsh town called Landofsavingmoneyandgettingtherightdealgogogocompare, which is Gio's hometown. But in July 2015, Gio returned to the adverts.

He is played by Welsh singer Wynne Evans.
