The brief behind this rewrite
The example below uses one product throughout, a reusable insulated water bottle sold on a standard ecommerce product page, so the before and after can be compared directly. The original description is the kind that gets written when someone lists everything the product has and calls it finished. It is not badly written. It simply never asks what any of those specifications mean to the person holding a phone and deciding whether to buy.
Features tell you what it does, benefits tell you why you care
A feature is a fact about the product: its capacity, its material, its finish. A benefit (see the glossary for the full definition) is what that fact changes for the person using it. A spec sheet gives you the first. A product description that sells has to give you the second, and most feature-heavy copy stops at the first because it is easier to write.
Before: the feature list
- 500ml capacity
- Double-wall vacuum insulation
- 18/8 food-grade stainless steel
- BPA-free construction
- Leak-proof lid with silicone seal
- Powder-coated exterior finish
- Available in six colours
Every line here is true and none of it is wrong to include. The problem is that the reader has to do the translating themselves: work out that double-wall vacuum insulation means the coffee is still hot at eleven, that 18/8 stainless steel means the water does not taste of metal, that a silicone seal means the bottle can go in a bag without a second thought. Ask a reader to do that translation and most will not bother. They will read the list, feel nothing in particular, and leave.
After: the rewrite
Fill it before you leave the house and it is still properly cold at lunchtime, or still hot if you filled it with coffee instead: the double-wall insulation is doing that work quietly in the background. The lid seals tight enough that it goes in a bag next to a laptop without a second thought, no damp sleeve, no leak in the bottom of the bag. It is made from food-grade stainless steel, so what you taste is the water. Six colours, so it does not have to look like everyone else's on the desk.
What changed, line by line
500ml capacity became a lunchtime timeframe. Double-wall vacuum insulation stayed in the copy but stopped being the headline term; the sentence now says what the insulation does. 18/8 food-grade stainless steel and BPA-free were folded into one plain claim, that the water tastes of water, because two separate technical assurances were doing the job that one sensory sentence does better. Leak-proof lid with silicone seal became a scene, a bottle in a bag next to a laptop, because a scene the reader recognises does more work than a mechanism they have to trust on your word.
Structure it so a scanning reader can find their answer
A product page is read in two different ways by two different readers, sometimes by the same reader twice. The first pass is a scan: does this solve my problem, roughly, yes or no. The second pass, once the answer is yes, is a check: does it actually hold the specific numbers I need, the exact capacity, the exact material, the dimensions. Benefit-led copy answers the first pass. It does not replace the specification, it sits above it. The rewrite above belongs at the top of the page, in short paragraphs a thumb can scroll past in a few seconds. The full spec list, capacity, material, dimensions, care instructions, still belongs on the page, lower down, in a table or a short list a reader can check once they have already decided they are interested. Cutting the spec list entirely to make room for benefit copy solves the wrong problem; the fix is ordering the two correctly.
Two ways to take this further
If you want a second opinion on a description you have already written, run it through the readability and clarity checker, which flags long sentences and passive constructions but cannot tell you whether the benefits are the right ones for your reader, so treat the score as a starting point. For the fuller picture, the guide to writing a product page covers structure, image copy and the spec table in more depth than fits in one clinic rewrite.
