Editorial and corrections policy

BigBoards is an independent research site. It does not sell OOH inventory and does not accept payment for rankings or favorable operator coverage.

Sourced facts link to a record. Derived figures show a formula. Editorial interpretation is written as interpretation and cannot silently upgrade correlation into causation.

Material factual errors are corrected on the affected page with an updated review date. If a source revises a number, downstream calculations are recomputed.

We do not fabricate local prices, inventory availability, display ownership, market share, audience performance, reviews or company affiliations. Unsupported completeness is less useful than an explicit gap.

Corrections can be submitted at research@bigboards.io with the page URL, disputed statement and a primary source. This address is published for editorial correspondence; it is not a media-sales channel.
