Check provenance before using a benchmark

Trace the individual record

For a procurement or research review, request the actual source URL, capture date, source type, asset identifier and applicable permission or terms. An example schema is not proof that every historical row has all fields populated. Check the records used for your comparison.

Separate source and outcome

A transparency-library asset is not automatically accompanied by measured performance. Record where an outcome came from, the metric definition and its observation window separately. Missing outcomes cannot validate predictive accuracy. Platform and market coverage must be assessed for the actual cohort.

Keep customer material distinct

A private creative upload is not blanket permission to publish it or add it to public research. Confirm the agreed purpose, access and any publication permission. The current privacy notice, service terms and data-processing documents govern the service; this editorial guide does not replace them.

Ask for the applicable evidence

For a specific engagement, request the relevant record rather than relying on a library-wide percentage. Record unresolved provenance or permission questions before reusing material. For personal-data handling, retention and processors, consult the current published policies linked below.

Historical correction

Earlier library counts, license-class percentages, blanket sourcing assurances and statements that advertising cannot contain personal data have been removed. They were not supported by a complete verified inventory in this review. The illustrative audit row was also removed so it cannot be mistaken for an actual production record.
