Lewis Corner of Digital Spy gave the song a positive review, stating:

"The end result, Ella's first single 'Ghost', would make a worthy winner's launch, let alone someone who fell victim to the mid-series shock elimination. "I keep going to the river to pray/ 'Cos I need something that can wash out the pain," Henderson professes over stomping Americana-folk beats and taut guitar twangs, falling somewhere between the rootsy heart of Adele and the pop sensibility of Leona Lewis. It's dark, it's brooding and it's full of pain, but most importantly for Ella's concerns, it's an unforgettable debut." ^[13]

"Ghost" was commercially successful, entering at number one on the UK Singles Chart on 15 June, selling 132,000 copies in its first week on sale.^[14] The song remained number one in the UK for a second week, outselling 5 Seconds of Summer's "Don't Stop" by 3,000 copies.^[15] The single has been certified triple Platinum by the BPI for sales and streams of over 1,800,000 units in the UK.
