"Youngblood" debuted at number one in Australia, becoming 5 Seconds of Summer's third number-one album in their home country. It debuted atop the albums chart at the same week that the title track was number one for a fifth week on the singles chart.
In the United States, the album became the band's third-number one album on the Billboard 200, debuting with 142,000 album-equivalent units (including 117,000 in pure album sales). It debuted ahead of The Carters' album, "Everything is Love."
The success of "Youngblood" made 5 Seconds of Summer the first Australian music act with three number-one albums in the United States and led to them being the first band (not vocal group) to have their first three full-length studio albums debut on top of the Billboard 200.
"Youngblood" received positive reviews from critics.
Matt Collar of AllMusic wrote that the group embraced a "slick dance-pop sound" on their album and considered it as "a transition they've been hinting at ever since their 2015 sophomore album, Sounds Good Feels Good [...] the transition to a streamlined, post-EDM-flavored sound isn't really a shock, even if it's a notable shift."
He concluded, "[it is] a useful sound for 5SOS to embrace, and helps position them nicely as a lighter version of The 1975 or Imagine Dragons. While there are plenty of hooks here, the dancey pop attitude is matched by a growing maturity with lyrics about growing weary of the party scene, the emptiness of touring, and yearning for that one perfect love."
Brittany Spanos of Rolling Stone also commented on the transition and wrote that: "pop-punk is not a genre that's meant to carry a band through a full career. So it's not surprising that on their third album, [the group] have already aged out of the sound that built their success. Instead, Youngblood goes full pop, leaning into some Eighties inflection and foregoing the bratty, DGAF ethos of their earlier work."
However, she also felt that, "[a] downside of the new sound is that the boys lose a little bit of the spunk that made them big in the first place. The snottiness of pop-punk highlighted their natural humor, and while they've certainly grown as musicians, singers and writers, a bit of that goofy charm is missing."
