Establishing Admissibility Standards for Automated Telemetry in Programmatic Ad Disputes
Admissibility demands cryptographic hash chains, synchronized server timestamps, and documented error rates for all automated auction telemetry in dispute.
Ad Server Access Logs
Meaning
Raw data files containing every request made to a digital advertising delivery system. These ad server access logs contain the timestamp, IP address, user agent, and specific resource requested for every interaction. Access to these files allows a buyer to verify the volume of requests against the invoices received from a publisher.
They represent the primary source of truth for technical audits in the programmatic supply chain.
Operational Utility
Information found in these files identifies the origin of non-human traffic or technical failures that result in wasted spend. Analysis of ad server access logs helps engineers diagnose why certain assets failed to load on specific browsers.
Contractual Compliance
Service level agreements often mandate the retention of these records for a minimum period to support financial reconciliation. Because ad server access logs provide a granular view of every transaction, they function as the final arbiter when a demand partner disputes a billing figure. Verification of supply through these logs is the only way to confirm a claim.
If a publisher cannot produce these logs, the buyer may have the right to withhold payment for unverified impressions.
Forensic Analysis
Automated systems parse the entries to identify patterns associated with domain spoofing or click injection. These ad server access logs expose the true path of a request through various intermediaries.
