Search Engine Optimization (SEO) Expert Witness
Search engine optimization (SEO) disputes are among the most misunderstood matters that reach litigation, because ranking behavior is often assumed to be either fully controllable by an agency or entirely random, when in reality it is neither. Bill Hartzer has worked directly in SEO since 1996 and provides expert witness services in matters involving SEO performance, ranking losses, algorithmic changes, alleged SEO malpractice, and disputes over search visibility. With more than 25 years of hands-on SEO experience — not theoretical or academic exposure, but day-to-day work managing rankings for real websites — he provides clear, defensible explanations of how search engines behave and why rankings change.
Attorneys retain Bill in these matters because SEO disputes require someone who can distinguish between a ranking decline caused by a documented Google algorithm update, one caused by a competitor's more effective content and links, and one caused by an agency's substandard or negligent work. That distinction is frequently the entire case.
Common SEO Litigation Topics
SEO litigation topics tend to cluster around a small number of recurring fact patterns, each of which requires a slightly different analytical approach. Some matters turn on whether an agency's conduct met accepted industry standards; others turn on external factors, such as a Google algorithm update, that had nothing to do with any party's conduct. Sorting out which category a given dispute falls into is often the first and most important step in the analysis.
SEO Fraud & Misrepresentation
Allegations that an agency misrepresented its methods, results, or the work it actually performed on a client's behalf.
Ranking Drops & Deindexing
Sudden losses in visibility or a site's removal from search results entirely, and what caused it.
Manual Actions & Penalties
Google penalties tied to a specific policy violation, and who is responsible for the underlying conduct.
Agency-Client Conflicts
Disputes over deliverables, reporting, and whether contracted SEO work was actually performed.
Backlink & Link Spam Issues
Paid links, link schemes, and negative SEO campaigns designed to harm a competitor's rankings.
Technical SEO & Performance
Site architecture, crawlability, and Core Web Vitals issues raised in vendor or platform disputes.
How Bill Contributes to a Case
Bill analyzes ranking history, organic traffic patterns, Google Search Console data, crawl logs, backlink profiles, and technical signals to determine the likely causes of a website's performance changes. His written reports and testimony translate technical SEO behavior into plain, courtroom-appropriate explanations that judges, juries, and opposing counsel without a technical background can follow and evaluate on the merits.
