Author Reki Kawahara wrote the first volume of Sword Art Online in 2002 and intended to submit it for the Dengeki Game Novel Prize, but refrained as he exceeded the page limit. He instead published the series as a web novel. Shortly after his other series won the Dengeki Novel Grand Prize in 2008, Sword Art Online was published in print.


The series placed 1st on the Kono Light Novel ga Sugoi! ranking under Best Light Novel category in 2012 and 2013.
