Writing product descriptions that actually help buyers

A product description has one job: help someone decide whether the product is right for them. That sounds obvious, but a lot of descriptions drift into vague praise or copy lifted straight from a supplier sheet. Neither helps a buyer. The ones that work read like a knowledgeable person answering the questions a shopper would ask if they could hold the product in their hands.

Here is how to write descriptions that do that work, whether you are filling out a new catalogue yourself or briefing someone to do it for you.

Lead with the benefit and who it is for

Open with what the product does for the buyer and who it suits. A waterproof jacket is not just waterproof; it keeps a dog walker dry on a wet morning without feeling heavy. That framing helps the right person recognise themselves and move on quickly, and it helps the wrong person rule it out, which saves you a return later.

Keep the opening short. One or two sentences that name the main benefit and the intended use are enough to set the scene before you get into detail.

Cover the practical specifics

Once the buyer is interested, they need facts. These are the details people scan for before they add anything to a cart, and missing one is a common reason a sale stalls. A bulleted list is often the clearest way to present them, because it lets someone find the single number they care about without reading a paragraph.

• Size and dimensions, with a fit note where it applies (runs small, true to size)
• Materials and what they are made from, including any care instructions
• What is included in the box, and what is sold separately
• Compatibility, weight, capacity, or other numbers specific to the product

Answer the obvious questions

Think about what a customer would ask before buying, then answer it in the description so they do not have to email or guess. Is it machine washable? Will it fit a standard frame? How long does the battery last? A quick way to find these is to read your own product reviews and support messages; the questions that come up again and again belong in the copy.

Write in your brand voice while you do it. If your shop is warm and plain-spoken everywhere else, a stiff, technical description feels out of place. Consistency in tone builds the same quiet trust as a tidy storefront.

Make it scannable, and write for people first

Few shoppers read top to bottom. They scan. Short paragraphs, clear subheadings, and bullets for specifics let someone find what they need in a few seconds. A wall of text hides your strongest points; breaking it up surfaces them.

It helps to include the words shoppers actually type into search, but write for the person first and let those terms appear naturally. If buyers call it a duvet, call it a duvet. What you want to avoid is hype and claims you cannot back up. Skip the empty adjectives and any promise you would not want to defend, and describe the product plainly enough that the right buyer says yes and the wrong one walks away informed. That honesty is what turns a description into a tool that helps people decide, which is the point of writing one at all.
