In the United States, the album was released on November 11, 2008, exclusively via Target.

The compilation album received positive reviews from music critics, who praised her musical career over her first decade since entering the music industry. The album debuted at number nine on the US Billboard 200, and has sold over 614,000 copies in the United States as of 2018. Internationally, it entered the top ten of record charts in multiple countries, including Australia, Ireland, Japan, Austria and France, and achieved several certifications.

Background
In September 2008, it was announced that Aguilera would release a greatest hits album titled Keeps Gettin' Better: A Decade of Hits, whose distribution rights in the United States belonged to Target retailer via her record label RCA Records. On the compilation's title, Aguilera said: "I'm looking forward to the next 10 years, which is partly why I named the album, Keeps Gettin' Better, 'cause it does". People who pre-ordered the compilation would receive a free digital download version of the single "Keeps Gettin' Better". During an interview with the Los Angeles Times, Aguilera explained that Target "got such a great creative team", and that's why she worked with the retailer for the album.

Content
Released in November 2008, Keeps Gettin' Better: A Decade of Hits opens with Aguilera's "early chart-toppers" and first four singles: "Genie In a Bottle", "What a Girl Wants", "I Turn To You" and the radio version of "Come On Over (All I Want Is You)", all from her self-titled debut album. The compilation continues with her 2001 collaborations "Lady Marmalade" and "Nobody Wants to Be Lonely"; the former with Pink, Lil' Kim, Mýa and the latter with Ricky Martin.

The compilation also included Aguilera's "professional and sexual coming-of-age" songs from her 2002 studio album Stripped including: "Dirrty", "Fighter" and "Beautiful". Several media outlets noted the absence of "Can't Hold Us Down" from the compilation. The songs are followed by her most recent efforts at that time, her fifth studio album, Back to Basics, which was described as a "pop-soul-jazz-blues opus" by Digital Spy writer Nick Levine. The compilation featured the three singles from the album including the critically acclaimed top-ten song "Ain't No Other Man", "Hurt" and the "tongue-in-cheek retro-pop" song, "Candyman".

The compilation ends with four new songs produced by Linda Perry. Two of these songs are remakes of her previous singles, "Genie 2.0" ("Genie in a Bottle"), and "You Are What You Are (Beautiful)" ("Beautiful"). The former received comparisons to Kelly Osbourne's "One Word" and was described as "stellar sonic". The other new songs were "Keeps Gettin' Better" and "Dynamite". A Rolling Stone reviewer noted the new material was electropop themed and reminiscent of Lady Gaga's work.

Some of Aguilera's songs were also added to international versions of the compilation. The radio edit of "The Voice Within" from Stripped was added to the UK and Japanese editions while "Ven Conmigo (Solamente Tú)" and "Falsas Esperanzas", both from Mi Reflejo and the former being the Spanish version of Aguilera's number-one song "Come On Over Baby (All I Want Is You)", were added to the Spanish and Argentine editions.

Promotion
"Keeps Gettin' Better" was released as a single from the album and was released on September 22, 2008. An accompanying video saw Aguilera as Catwoman and performing in front of green screens. The single experienced moderate commercial success, peaking at number seven on the US Billboard Hot 100 and number four on the Canadian Hot 100. On September 7, 2008, Aguilera performed a medley of "Genie 2.0" and "Keeps Gettin' Better" at the 2008 MTV Video Music Awards in Hollywood. On November 23, Aguilera opened the American Music Awards of 2008 with a seven-minute medley of her previous singles, which included "Beautiful", "Keeps Gettin' Better", "Genie in a Bottle", "Dirrty", "Ain't No Other Man", and "Fighter".

"Dynamite" was released as a promotional single in Japan on November 20, 2008. It was released to the iTunes Store in the United States, too. On January 14, 2009, the song received airplay in Russia, as reported by Tophit. It reached number 146 on the Russian Airplay Chart.

Critical reception
Keeps Gettin' Better: A Decade of Hits received generally positive reviews from music critics. AllMusic writer Stephen Thomas Erlewine commented that the compilation "proves that no other teen pop singer of her era has a better track record than Christina and if the new songs are any indication, the title of this hits comp is no lie either." Nick Levine from Digital Spy noted the "spunky attitude" of the compilation and compared her recordings to those of Britney Spears: "She may have started out with similar material to another Mickey Mouse Club alumnus, but Aguilera moved on to bigger and better things more quickly than Britney." He further complimented Aguilera's songwriting skills.

Chris Willman from Entertainment Weekly noted the lack of traditional Aguilera styles on the new songs, stating: "The singer has banished melisma and belting from these electronic confections, and her chops sound just as hot set on simmer." Writing for Sputnikmusic, Nick Butler positively reviewed Aguilera's new material, saying: "Christina the pop singer is dead, long live Electro Christina [...] At any rate, these four tracks are more than enough to build anticipation for what could be a very, very good album." In a mixed review, an editor from Rolling Stone said that the album's "ten stellar singles are weighed down by four bland attempts at 2008's trendy, Lady Gaga-jacking electropop."
