Siwa was a top-5 finalist on the second season of the series Abby's Ultimate Dance Competition and the youngest contestant on season 2.^[5] She appeared on the show with her mother and was eliminated in week 9.^[6]

Siwa began auditioning for Abby Lee Miller's ALDC dance competition team in 2014 and was selected for the team in early 2015.^[7] At the same time, she began to appear on the Lifetime reality show Dance Moms, which follows the ALDC team.^[8][9]

In May 2016, Siwa released "Boomerang" for digital download and a previous single, "I Can Make U Dance". "Boomerang" addresses the subject of online bullying.^[8][10] Its video has been viewed more than 450 million times and received over 2.5 million likes. In 2018, Siwa was named the Breakout Artist of the Year by Vivid Seats.^[11]

In 2018, Siwa announced that she would be going on her first major concert tour in 2019, entitled D.R.E.A.M. The Tour. It is scheduled to visit a mixture of theaters, outdoor amphitheaters and stadiums, as well as indoor arenas in a total of 52 cities across the United States and Canada. Additionally, other performances will take place in the United Kingdom. The tour is scheduled to begin in Phoenix, Arizona on May 17.

Known to audiences for wearing large, colorful bows in her hair, Siwa released a line of bows in 2016: JoJo's Bows, to be sold at Claire's, a fashion-accessory company aimed at 6-to-12-year-old girls. Her bows found a strong following among primary-school pupils in the United Kingdom and were ultimately subject to bans as teachers discovered that students unable to afford the bows, which retail for approximately £8 to £12 each, were bullied by their peers. Other reasons these schools gave for the bans was they were a distraction, harmed students' concentration, and violated the schools' dress code policies.^[13] Due to the bows' price and popularity, some stores began selling similar, homemade bows.^[14] In 2017 Siwa, whose bows are heavily featured in her music videos and general wardrobe, said they are a "symbol of power, confidence, believing-ness."^[14]

Siwa subsequently partnered with the American department store J. C. Penney to release a line of accessories, bedroom decor, and a doll made in her likeness, and has released several books aimed at young children.^[15][16][16]

In June 2019, the FDA issued a warning about dangerous levels of asbestos in a JoJo Siwa-branded cosmetics kit, prompting Claire's to recall the product.^[17][18]

JoJo signed with Nickelodeon in 2017. She has been on Blurt with Jace Norman, Lip Sync Battle Shorties with Nick Cannon, and much more.
