Her username, SSSniperWolf, comes from Sniper Wolf, is one of the main antagonists and bosses of Metal Gear Solid, It was her favorite game as a kid too. Alia claims that the 'SS' in her name does not mean anything.

Alia originally started her YouTube career in early 2011 on a channel called sexysexysniper making short vlogs. The channel accumulated 50,000 subscribers until 2 years later however when she made a new channel on January 19, 2013, and deleted the old one around mid-2013 most likely due to the name. Since 2017, the majority of the videos that she uploads are reactions and TikTok videos, along with occasional gaming and challenges. From 2020 onwards, she regularly made it to the Trending Page, gaining her intense popularity.

Alia is also known to appear in Dhar Mann's videos as herself. In the videos she is the idol of Sam/Psycho Mantis (played by Sofia Chicorelli Serna), a girl who wants to be a gamer just like her, despite her sexist mother not allowing her. However after Alia gives her a PS5, she becomes a professional gamer and earns a lot of fame and money, and her mother discards her sexist beliefs. This in itself brings more issues such as a bully targeting her due to her fame, but she earns his friendship by paying for his rent and car. "Sam" and SSSniperWolf appear in more miscellaneous videos, though with minor roles.
