Bullet points and description copy should sell benefits (the problem the product solves for the buyer) rather than features (what the product literally has or does). A practical test for whether copy has slipped into generic feature-listing: if a competitor selling a different product in the same category could paste the same bullet onto their own listing without it sounding out of place, the bullet is too generic and needs to be rewritten around a benefit specific to this product.
This sits alongside Amazon Listing Optimization: SEO vs. Conversion Optimization as a conversion-side (not keyword-relevancy-side) copywriting discipline — the goal is to persuade a human reader, not just satisfy the algorithm.
