The song is a motivational piano-led power ballad about hope and overcoming hardship.

[1] On 14 May, Goodrem premiered the song during a livestream on Facebook and Instagram, and released it on streaming services immediately after.

The song was included as a B-side on the CD edition of Goodrem's follow-up single "Paralyzed".

[2] "Keep Climbing" was positively received by critics upon its release, with Idolator remarking that the song provides "the kind of stripped-back, vocal showcase that Delta has perfected since breaking through with "Born To Try" and "Lost Without You" in 2002" and that it "might just be her best single since "Wings"".

[3] Thomas Bleach commented "beginning with just simple piano keys, she starts to add layers with strings and soulful melodies that turn into a beautiful gospel moment towards the end of the song where the choir powerfully sings the phrase "keep climbing"", and that "the song ripples with perfect waves of emotions that drive the structure and climatically builds to give you a really beautiful and special moment.
