Girl Online received a mixed review from Anita Singh for The Daily Telegraph, who awarded it a score of three out of five. Singh found the romance to be unrealistic and stated that "the teenagers in this book bear no resemblance to any I have ever met", while also acknowledging that she is "not Zoella's target market" and that "times must have changed". She further states that while the book itself is "sugary as a frosted cupcake", "so is Zoella and six million YouTube subscribers love her that way" and that "Sugg has tapped into a truth"; "growing up doesn't have to mean leaving childish stuff behind."^[28]

The novel was well received by Daisy Wyatt, for The Independent, who found the novel "difficult to fault", calling it "fun and easy to relate to, while also having a positive message". Wyatt found, however, that "while Girl Online does teach sound advice to teenagers about being cautious of their online activity", Sugg has "found fame and fortune in sharing personal details on the internet" and felt that her fans are more likely to copy her than the fictional Penny.^[29] The novel was well received in The Guardian, with reviewer 'lilybelle' stating "I could relate so much to everything" and that "This book inspired me... I literally feel as though I've changed overnight". She also found that Sugg "made Penny a bit too similar to herself", making it "confusing at times", but described the novel overall as "special and inspiring."^[30]
