Verify marketing claims against actual evidence
Check every claim on a page or in a campaign against the proof behind it.
What this prompt helps you do
A claim-by-claim verdict with supporting evidence, unsupported claims named, and defensible rewordings.
When to use it
Copy is nearly final and contains performance, comparison, or outcome claims.
What to prepare
The goal, relevant source material, constraints, examples, and the decision or action this should support.
How to get a strong result
Unsupported claims must be named as unsupported rather than softened; hedged language does not fix an unproven claim.
How to use this prompt
Replace each placeholder with accurate context. Paste the complete prompt into Claude, review the response critically, resolve important questions, and use it as a considered input to the next decision—not as an unchecked final answer.
