Professional Background
Bill Hartzer is the founder of Hartzer Consulting, LLC and of DNAccess, and has worked in the internet industry since 1996. His career began in-house at an international software and telecom company, where he managed multilingual websites and handled early SEO efforts as search engines became serious business tools. He subsequently moved into agency and independent consulting work, managing SEO, domain name portfolios, and digital marketing campaigns for organizations ranging from startups to Fortune 500 companies.
Over more than 25 years, Bill has advised marketing teams, software companies, law firms, domain registrars, investors, cybersecurity professionals, government agencies, and enterprise organizations on matters at the intersection of search engines, domain names, digital advertising, internet infrastructure, web analytics, and online reputation management. That breadth is unusual in the expert witness field, where most practitioners specialize narrowly in a single discipline.
