Rousey, the UFC's female bantamweight champ, ranked fifth on the list, just one spot behind Lindsey Vonn and four behind No. 1-ranked Tim Tebow.
Rousey, who appeared last night on Jimmy Kimmel's late night show, is slated to put her belt on the line against Miesha Tate on Dec. 28 in Las Vegas, Nev., in the co-main of UFC 168.
Her unique combination of fighting skill, personality and good looks helped her explode in popularity over the past year, so it shouldn't come as much of a surprise that people are searching her name online.
As for Ortiz, his spot on the list was a bit of a surprise being that he hasn't fought in over a year.
Ortiz, who took the No. 7 spot on Yahoo's "most searched athletes" list, was expected to fight MMA legend Quinton “Rampage” Jackson this past month in what was supposed to be Bellator’s first-ever pay-per-view event, but he dropped off the card due to a neck injury.
Ortiz ranked one spot behind Lamar Odom on the list.
Being that he's now 38 years old and hasn't competed in 17 months, it's definitely a shocker that fight fans are still searching his name so much. It makes a bit more sense when you consider that he had a very public dispute with his ex, former adult film star Jenna Jameson.
Rounding out Yahoo's list of "most searched athletes" was Carano, a former Strikeforce fighter and the original face of women's MMA.
While Carano hasn't fought in a cage since 2009, she's been extremely busy with acting work. Since Carano is still so active, it shouldn't come as much of a surprise that fight fans are searching her name online.
Carano ranked No. 10 on Yahoo's list, just one spot behind tennis star Maria Sharapova.
