Can releases use claims like “No.1”, “best”, or “industry-leading”?

Not without solid evidence.

Absolute claims such as “No.1,” “best,” “only,” “most advanced,” or “industry-leading” may trigger media review, advertising compliance, or consumer-protection risk—and reduce trust.

If you have authoritative data, independent awards, third-party research, or a clear evaluation scope, state the source, methodology, region, and time range. Rankings and reviews also need real criteria—they cannot hide unverifiable claims.
