A Career Built on Search Engines, Domains, and the Infrastructure Between Them
I'm Bill Hartzer, founder of Hartzer Consulting and DNAccess. For more than 25 years I've worked with businesses ranging from startups to Fortune 500 companies on technical SEO (Search Engine Optimization), website and domain migrations, search engine marketing, domain name strategy, and internet infrastructure. That work has put me inside thousands of websites, domain portfolios, and analytics accounts — and it's given me a working understanding of exactly how content moves across the internet, how search engines index and cache it, and how it disappears.
Internet defamation matters sit squarely at the intersection of those disciplines. Investigating a defamatory post, review, or video isn't just a legal question — it's a technical one: Where was it published? Who published it? Has it been indexed or cached? Is it still live? Has it been archived anywhere? What did it do to search visibility, traffic, or reputation? Those are the questions I've spent my career answering.
From Technical SEO Consulting to Expert Witness Work
My expert witness work grew directly out of my consulting practice. Attorneys and businesses began asking me to investigate and explain search engine behavior, domain ownership, and online advertising practices in the course of disputes — and internet defamation matters followed a similar pattern. Time and again, cases turned on questions that required someone who understood both the technology and how to explain it clearly: Was this review really left by a customer? Can this anonymous post be traced? Why isn't this profile in the Wayback Machine? What did this content actually do to the business's search rankings and revenue?
I've handled that kind of forensic internet investigation work for law firms, businesses, and individuals across the country, and I bring the same investigative rigor to internet defamation matters that I bring to domain disputes, UDRP proceedings, and SEO/SEM litigation.
I Am Not an Attorney
I am not a licensed attorney and do not provide legal advice. I do not determine whether specific content meets the legal standard for defamation in any jurisdiction, and nothing on this site should be read as a legal opinion or legal conclusion. My role is to provide technical investigation, evidence documentation, platform analysis, and expert testimony on the internet-technology aspects of a matter. Anyone who believes they have a defamation claim should consult a licensed attorney in their jurisdiction.
