O'Neil has also appeared in television commercials for MCI, Toyota, Nike, Resorts Casinos, FX Channel, Heineken, Virgin Cola, Mercedes-Benz, Vonage as well as print ads and/or articles for the likes of Sony, Coors Light and Ironman Magazine amongst others.
She gained widespread popularity on the Internet after appearing on Lisa Boyle's website and then on BlueNudes where she appeared in artistic nudes taken by photographer Tom Ruddock. Soon she started the official Linda O'Neil website, with her sister Lisa as webmaster, and her loyal fan base has grown steadily since.
In mid-May 2007 Linda's site stopped being updated and by 18 June 2007 Linda's website became only partially functional with certain (archival) links becoming totally inactive. By late November 2007 her domain address was no longer accessible. While no formal announcement was given, many of her fans believe she has retired from the modeling business. Linda has stated that she was having some personal issues and wanted privacy while dealing with them.
As of March 3, 2008, her web site splash-screen is back up with a "Returning Soon" message. As of April 8, 2008, the splash-screen still appears, but "Returning Soon" has been removed. As of May 21, 2008, contact links appear. As of May 22, 2008, a low-res streaming video of her Vonage commercial is also available.
