Google's no stranger to privacy-related controversy , which may explain the motivation behind its latest ad campaign. On Tuesday, the company will launch a series of ads across major newspapers, magazines and billboards, as part of its new "Good to Know" initiative, designed to make the internet "a safer, more comfortable place." According to Google, these ads will offer tips and advice on how to secure your personal information online, including details on how to protect your passwords from web predators. The entire campaign has a distinctly PSA flavor to it, though there's also a different subtext at work here, since Google is effectively branding itself as "the one you can trust." There are certainly some who would dispute that, but at a time when most privacy concerns are focused squarely on the government , it may be a good time for Google to crank up its PR machine.
