25+ Years in Search, Data, and Internet Investigations
I am the founder of Hartzer Consulting, LLC and DNAccess, and have worked for more than 25 years as a technical SEO, search engine marketing, and domain name consultant to organizations ranging from startups to Fortune 500 companies. My work spans technical SEO audits, website and domain migrations, search engine marketing campaign management, domain portfolio management and recovery, and internet investigations — experience that translates directly into the technical questions internet defamation litigation raises.
That breadth matters in defamation litigation specifically because these matters rarely stay confined to a single discipline. A single case can require understanding social media platform mechanics, search engine indexing and ranking behavior, web analytics, and sometimes domain or hosting infrastructure, all within the same engagement.
Litigation & Expert Witness Matters
I regularly serve as an expert witness in matters involving search engine optimization, search engine marketing, Google Ads and online advertising, web analytics, internet marketing, domain names and domain ownership disputes, and website traffic analysis. That work includes reviewing evidence, preparing expert reports, analyzing historical technical data, conducting forensic internet investigations, and explaining complex internet technologies in terms attorneys, judges, and juries can understand and rely on.
I have been retained by both plaintiff's and defense counsel across a range of matters, and I approach every engagement with the same standard of independence: my conclusions are dictated by the evidence and methodology, not by which side retained me, and I say so plainly when the evidence doesn't support the theory a client hoped for.
