Which of these ad copy examples is compliant with Amazon Ads’ Guidelines and Acceptance Policies for claims and substantiation?

The correct ad copy, "Super Power Batteries last twice as long as the leading brand Independent Example Lab test, May 2022," is compliant because it includes clear substantiation for the performance claim. Amazon Ads' policies require that any claims of superiority or specific performance metrics (e.g., "last twice as long") be backed up by verifiable evidence, and that the source and date of that evidence be explicitly stated in the ad copy. The incorrect option, "Super Power Batteries last twice as long as the leading brand," makes a strong performance claim without providing any substantiation, which violates Amazon's guidelines for truthfulness and transparency in advertising. Without substantiation, consumers cannot verify the claim, making it potentially misleading.
