Listing rules from Amazon, eBay, Shopify, Zalando and Alibaba set limits on title length, prohibited wording, attribute fields and text in images. Translating without them produces copy that reads well but cannot be uploaded, or that triggers review.
Keywords deserve separate treatment. Translating Chinese selling points literally often misses local search behaviour. We propose keyword candidates by category, place high-value ones naturally in titles and bullets, and keep existing brand product names and model codes.
Note: Etrans regularly handles document translation projects involving the international brands named above and is familiar with their terminology and layout conventions. Brand names describe document types and project context; they do not imply endorsement or authorisation by the brand owner.
