McCartney recalled: "I sat out by the pool on one of the sun chairs with my guitar and started strumming in E. And soon [I] had a few chords, and I think by the time he'd woken up, I had pretty much written the song, so we took it indoors and finished it up.

[11] Music critic Richie Unterberger considers that this "dramatic opening [lyric]" contains "an almost philosophical undertone of humility, acknowledging that the singer needs his woman not just to be happy, but also to be a better person".

[15] Rolling Stone has noted: "The tune's chord sequence bears Brian Wilson's influence, ambling through three related keys without ever fully settling into one, and the modulations – particularly the one on the line 'changing my life with a wave of her hand' – deftly underscore the lyrics, inspired by McCartney's girlfriend, actress Jane Asher.

[18] The recording is noted for its layered backing vocals,[1] which McCartney, Lennon and George Harrison spent much of the three days attempting to perfect.

[20] In his book Revolution in the Head, Ian MacDonald also comments on Harrison's lead guitar part being given a mandolin-like tone via a Leslie speaker effect, before it adopts a "horn-like timbre" for the song's ending.

[21] Writing of its positioning in the running order, music critic Tim Riley says that "Here, There and Everywhere" "domesticates" the "eroticisms" of "Love You To", and he praises the composition as "the most perfect song" that McCartney had written up to that point.

[22] In his review for AllMusic, Richie Unterberger describes "Here, There and Everywhere" as one of its author's "outstanding contribution[s]" to the genre of "love ballads", and a song with "the sound of an instant standard".

"[12] Less impressed, Ian MacDonald admired the "ingenuity of the music", but concluded that "for all its soft-focus charm, the song's overall effect is chintzy and rather cloying.

"[17] In his chapter on Revolver in the book The Album, James Perone describes "Here, There and Everywhere" as a "mid 1960s love ballad that could find its way into the set list for bands at a senior prom" and a track that to some listeners appears "syrupy and mushy".

[23] Chris Coplan of Consequence of Sound pairs it with "Got to Get You into My Life" as songs that are "seemingly out of place" on Revolver amid the overtly psychedelic and experimental music that typifies the album.

"[25] McCartney re-recorded the song for his 1984 soundtrack album Give My Regards to Broad Street and also performed it for MTV in 1991, released on Unplugged (The Official Bootleg).
