Designed to promote Lavigne's discography, the majority of concerts on the Greatest Hits Tour took place in North America, while her European dates primarily consisted of festival appearances.

[2] At the end of 2023, Lavigne revealed a series of European festival dates, accompanied by select stand-alone concerts including performances in Pula, Croatia and Cardiff, Wales.

[6] For the opening show of the Greatest Hits tour, the Vancouver Sun's Stuart Derdeyn praised the performance for delivering a high-energy, nostalgia-filled experience that delighted longtime fans.

[7] Reviewing the same opening night in Vancouver, Alyson Eng of BroadwayWorld commended Lavigne's vocal performance and nostalgic appeal, though she mentioned some technical issues with the sound.

"[9] Reviewing the Mountain View concert, Jim Harrington of The Mercury News highlighted Lavigne's strong vocals and engaging stage presence, noting that the show featured "unfussy pop-punk pretty much from start to finish" and was well received by the crowd of longtime fans.

[13] Mike DeWald of Riff Magazine, also praised Avril Lavigne's Mountain View Shoreline show, stating that she "is in the midst of a renaissance" and her Greatest Hits tour is "a smashing success".

"[14] For her Canadian shows, Billboard stated that her concert in Toronto was acclaimed as a celebration of "her impressive career", as someone who "made her mark in the 2000s as a young singer making space for herself in a male-dominated pop-rock field".

[25] Journalists from Schwäbische Zeitung who were present as the Southside Festival wrote that, "for many people, the highlight of the night was likely Avril Lavigne", where fans "floated in nostalgia once more and enjoyed her upbeat songs".

[28] Rosie Long Decter from Billboard, also stated that "Avril Lavigne played one of the most popular sets at Glastonbury" as her "performance overshadowed the main stage."

The article concluded that "Glastonbury might have underestimated the star's contemporary appeal by booking her on a side stage, but the turnout made it clear Lavigne isn't losing her grip anytime soon.

[30] Alexis Petridis, for The Guardian, also reviewed Lavigne's concert at a British festival, noting that the audience was not just singing, but "cathartically emoting like mad" while perched on "people’s shoulders".

He also mentioned that the singer "pretty much commanded the stage from the get-go and had the crowd in the palm of her hand", with the audience "jumping, cheering, and singing out every verse at the top of their lungs".

The concert structure was also praised, highlighting that "the show featured everything from confetti cannons and pyrotechnics, alongside a few inflatable balls thrown around the crowd for good measure too".

The reviewer concluded that her show "is a testament that we don't necessarily have to be serious all the time",[33] likening the classic hits in Avril's setlist to the 2024 British album 'BRAT' by Charli XCX, as both celebrate their unassuming yet irresistibly catchy nature.

[35] Laura García Higueras for El Diario discussed the Greatest Hits concert at Mad Cool in Spain: "Avril Lavigne fulfilled her role for the festival's closing."

It was also noted that "within 10 minutes, the concert had already acquired the status of a significant event", particularly considering "this wave of nostalgia for Avril Lavigne is an unexpected twist that occurs just 10 years after the artist contracted Lyme disease".

They highlighted her role in "inspiring girls' grunge phases", with fans responding enthusiastically to her set list featuring hits like "Girlfriend", "Complicated", and "Sk8er Boi".
