Amazon provides tools that help with listing content and testing. They are useful, and they have limits that matter for creative work.
Manage Your Experiments lets eligible brands test images and A+ copy against the original. Eligibility and setup depend on the account, so we confirm them before a test is planned, not after.
A+ Content and Brand Store need Brand Registry. Where the account is eligible, these surfaces are open to the brand. Where it is not, the work is planned for the surfaces that are open, and the gap is stated at the audit.
Amazon's rules set what each image can contain, and the upload checks apply them. The tools do not brief a design, map an asset to its slot, or decide which claim belongs on which image. That work sits between the listing and the upload, and it is the part a creative service adds.
