Reputation911 | Founded by William DiAntonio

William DiAntonio established Reputation911 in 2010 to solve a problem that didn’t yet have a clear solution—what do you do when your name is under attack online?

At the time, people facing online defamation, targeted reviews, or damaging search results had few options.

As a licensed private investigator for 9 years, he has a wealth of experience in crisis management and protecting the professional brands of high-level executives and political figures. 

William recognized a pattern: many of the people coming to him weren’t just dealing with negative content. They were dealing with real reputational harm that threatened their careers, livelihoods, and businesses.

He applied the same principles he had used in his investigative work to the online world. For his first client, he didn’t just try to bury bad links. He tracked down the source.

“I wanted to see if it was possible to determine who was writing this unwanted content. From there I could determine if we would be able to remove or suppress this information from the web. Once I saw that this was possible, I set out to help other individuals and businesses in the same way. Reputation911 was officially incorporated in 2011.”

That strategic, personal, and thorough approach became the foundation of Reputation911. Since then, the company has helped hundreds of clients both across the country and abroad repair their digital reputations and take back control of their search results.

A Reputation Management Company with Investigative Roots

Before founding Reputation911, William spent over nine years in special investigations, working with companies to uncover fraud and deception. He built a reputation for knowing how to find the truth and helping others protect what matters most.

That background continues to shape how Reputation911 works today. When clients come to him facing a reputation crisis, William doesn’t rely on surface-level SEO tricks. He digs deeper, often identifying when damaging content is connected to a former employee, competitor, or coordinated attack.

William DiAntonio Answers Common Questions About Reputation911

Why does online reputation matter today?

I’ve seen firsthand how a single article, blog post, or review can damage someone’s future, both personally and professionally. Your name is often the first thing people Google. If they don’t like what they find, it can cost you opportunities before you ever get the chance to explain.

What is a reputation crisis?

A reputation crisis happens when you lose control of what shows up in search results. It’s often tied to a specific event—false accusations, bad press, personal disputes going public. I’ve worked with clients who were completely blindsided by it, and my job is to step in before the damage becomes permanent.

When should someone hire a reputation management company?

If you’re Googling yourself and seeing results you don’t control or recognize, that’s the time to act. Most people wait too long, hoping the problem will go away. I created Reputation911 to give people real tools and strategies—not just advice—to fix it.

What makes Reputation911 different from other companies?

Most firms take a one-size-fits-all approach. I don’t. My background in investigations means I look deeper—into where the content is coming from, why it’s ranking, and how to remove or suppress it for the long haul. Every case is handled in-house, and every strategy is tailored to the person, not the problem.
