The idea
Credibility may rise when relevant expertise supports a claim, but the authority must actually address the question being asked. The illustration shows an evidence template with source, method, scope and limitations, rather than pretending that an independent report or certification already exists; a visual template is not proof of network performance. Use this framework to connect each public assertion with evidence customers can inspect, and check whether the result applies to the locations, dates, services and conditions represented in the advertisement.
Use it thoughtfully
- Publish the source and relevant method.
- State scope, dates and important limitations.
- Remove claims that the evidence cannot support.
An example
In an illustrative network-quality page, a provider reserves space for an independent report and explains what its methodology would need to cover. Before making any real performance claim, the team supplies the actual report and limits the wording to what it demonstrates.
A question to try
Does the cited authority substantiate this exact claim for this audience, place and period?
A useful framework is a starting point, not a guarantee. Effects vary with the audience, product and situation. Use truthful evidence, respect customer choice, and test the result.
