Short version: Product copy explains who a product suits, what it helps them do and which features support that benefit. It gives customers concrete information for a buying decision.
What to include: Start with the use and main benefit, then add verified details such as material, dimensions, compatibility, package contents or care instructions. Explain relevant limitations and conditions of use.
Illustrative example: For a bag, dimensions, strap length and fastening may be more useful than a broad quality claim. Link a benefit to its feature: an internal pocket helps separate small items. Only use that description when the actual product supports it.
Before publishing: Can someone choose the right size or variant from the information? Are important conditions easy to find? Can you support the claims? Avoid relying on repeated keywords or unexplained superlatives.
Use customer questions, return reasons and product-page behaviour to guide revisions. Copy, photographs, price and delivery information should work together to help people decide.
