Following her performance of "Fields of Gold", Walsh told her she gave the "performance of the night.

Coyle joined Cheryl Tweedy, Sarah Harding, Nicola Roberts, and Kimberley Walsh to comprise the new girl group Girls Aloud, formed through the show by a public vote on 30 November 2002.

Girls Aloud was increased to £30 million the following year, following Cheryl Cole's appearance on "The X Factor". All five members were included in a 2010 list of Britain's richest stars under 30. Reviews of Girls Aloud's debut album noted the high quality of the album compared to output from other reality show contestants.
