Analytics Forensics Expert Witness

Digital analytics systems record how visitors arrive, what they do, and whether they convert. In many disputes, those metrics are central evidence. Bill Hartzer provides analytics forensics services, reviewing tracking setups, logs, and reports to determine what the data truly shows.

When Analytics Forensics Is Needed

• Conflicting reports between agencies and clients
• Unexplained drops or spikes in reported traffic
• Suspected misconfiguration of tags or tracking codes
• Disputes about whether campaigns produced conversions
• Questions about data integrity or manipulation

Forensic Review Areas

• Tag and pixel configuration (e.g., Google Analytics, GA4, Google Tag Manager)
• Channel and source attribution rules
• Event tracking, goals, and funnel configuration
• IP filters, spam filtering, and bot-exclusion settings
• Exported logs and raw data where available

Bill’s analysis focuses on how the analytics system was built, what it actually measured, and whether the numbers being cited in a dispute accurately reflect user behavior.
