PPC Expert Witness for Advertising Disputes and Litigation
Advertising disputes often hinge on data, platform settings, and what a reasonable pay-per-click (PPC) professional would have done. PPC expert witness Bill Hartzer helps legal teams understand those details and explain them clearly.
Independent PPC Expert Witness Analysis
Many cases involve advertising accounts that have been running for months or years. Budgets have been spent, campaigns have been restructured, and new bidding features have been turned on and off. Sorting out what happened, why it happened, and whether those choices were reasonable requires the perspective of a PPC expert witness who has managed and audited real accounts.
As a PPC expert witness, Bill reviews accounts, change history, tracking, and analytics with an eye on both technical accuracy and practical marketing realities. He focuses on the data, but also on how decisions were made, documented, and communicated between the parties.

Click Fraud, Wasted Spend, and PPC Damages
Some advertising disputes center on suspected click fraud and invalid traffic. Others focus on wasted budget and missed revenue, which call for a detailed PPC damages analysis grounded in platform data and business metrics.
In many matters, the question is whether account management met a reasonable PPC standard of care. That includes how often campaigns were monitored, how quickly problems were addressed, and whether the account structure and targeting matched the stated goals.
These pages collectively explain how a PPC advertising expert witness evaluates alleged mismanagement and quantifies the financial impact.
Platform and Channel Expertise for PPC Cases
Modern PPC rarely lives in a single platform. Many cases involve a mix of search, display, and paid social. The Google Ads audit expert witness page describes how campaigns, keywords, audiences, and change history are reviewed in search advertising accounts.
Some disputes also include platform-specific issues, which are discussed on the Microsoft Ads expert witness page and the paid social ads expert witness page. Together, these resources show how a PPC expert evaluates search and social channels in the context of a single matter.
If your case spans multiple platforms, the PPC expert witness services page outlines how those channels can be reviewed together in a cohesive engagement.
Franchise, Agency, and Contract PPC Disputes
PPC often sits at the center of franchise systems, multi-location brands, and agency–client relationships. The franchise PPC expert witness page covers shared budgets, territory conflicts, and lead ownership questions that frequently arise in those matters.
The agency PPC dispute expert witness page focuses on expectations, optimization practices, and transparency in agency–client agreements. The PPC contract disputes expert witness page explains how scope of work, performance promises, and account control provisions intersect with actual account activity.
These pages help legal teams quickly see how PPC expert witness testimony can support claims or defenses in relationship-driven disputes.
PPC Evidence, Tracking, and Attorney Resources
Advertising claims are backed by evidence. The PPC evidence in litigation page outlines the types of data that commonly appear in discovery, including account exports, search term reports, change logs, and analytics records.
Many disagreements come down to whether tracking and attribution were set up correctly. The conversion tracking expert witness page explains how tags, analytics, call tracking, and CRM systems fit together. When evaluated properly, those systems show how leads and revenue should be tied back to PPC.
For teams that are newer to PPC, several resources provide context in plain language: What is PPC? offers a straightforward overview of pay-per-click advertising. The PPC glossary for attorneys gives concise definitions of common terms used in contracts, reports, and expert opinions. The what a PPC expert witness does page connects these concepts directly to expert witness work.
