Product page copy: answer buyer questions with accurate details and examples

Editorial follow-up: choose a representative preview
A preview should show what a buyer can reasonably expect from the delivered item. If a demonstration uses optional software, additional accessories or a more expensive package, explain that beside the example.

For digital files, show enough structure to assess usefulness without exposing anyone's confidential data. Label invented demonstration data clearly. The goal is to make the product understandable, not to create a polished example that the purchased version cannot reproduce.
