Good affiliate content should let readers distinguish seller information from independent evidence.
Used for current product positioning, package information, directions, ingredient names, pricing, shipping and guarantee language. These sources describe what the seller says and are not independent proof of every product claim.
When discussing an ingredient or health topic, independent medical or scientific references should be used where available. Evidence about an individual ingredient should not automatically be presented as evidence about the finished product.
Search-engine guidance is used for site structure and disclosure practices. Regulatory terminology is kept conservative so facility-registration language is not confused with FDA approval.
Online product pages can change, disappear or present different information across domains. The current product label and live seller checkout should be the final reference for purchasing decisions.
