Start with what the buyer wants to know
A product description has a practical job: to give a shopper enough information to decide. Online, people cannot pick things up, try them on or ask a shop assistant. The description stands in for all that.
So instead of starting with adjectives, start with questions. If you ran a physical shop, what would customers ask about this item? Those questions, answered clearly and in the order people want them, are the backbone of a useful description.
Common questions include:
- What is it, exactly?
- Who is it for, and what is it for?
- What size is it? Will it fit or work with what I have?
- What is it made of?
- How do I use, install or care for it?
- What is included, and what is not?
- What are the delivery and returns terms?
- What are the limits or downsides?
Not every product needs every answer, but gaps in this list are often where hesitation lives.
A simple structure
Many descriptions work well with this order:
- A plain opening line stating what the product is and who it is for.
- A short benefit-led paragraph explaining why someone would want it.
- Key details in a short list: dimensions, materials, capacity, compatibility.
- What is included (and anything that must be bought separately).
- Care, use or setup notes.
- Delivery and returns or a pointer to where those appear.
Illustration, using an imaginary canvas tote bag:
A sturdy canvas tote for everyday errands, with an inside pocket for keys and a phone. It holds a laptop up to 13 inches, plus a few books, and the long handles fit comfortably over a coat.
Details: cotton canvas, cotton lining, one inside zip pocket. Size: 38 cm wide, 40 cm high, 10 cm deep. Machine washable at 30 degrees; air dry. Not waterproof.
Notice what it avoids: no “must-have”, no “amazing”, and no claims it cannot back up. It also says what the bag is not (waterproof), which can prevent returns and builds trust.
Turn features into reasons
A list of specs is useful, but a reader still has to translate it. Pair each important feature with a plain explanation of why it matters: “wide base so it stands up on its own”, “padded strap, which helps when carrying heavier loads”. The translation method is described under features and benefits. Keep the benefit grounded in something the product genuinely does, not a promise about how it will change someone’s life.
Be specific and measurable
“Roomy” and “lightweight” mean different things to different people. Give numbers where you can, and check them: dimensions, weight, capacity, battery life under stated conditions, number of pieces. If a figure varies, say so (“approximately”). If you do not know a number, measure it before you publish, or leave the claim out.
Check any calculation shown. For instance, if you list a set as “4 mugs, 300 ml each”, a reader might reasonably work out the total of 1,200 ml; make sure the details are consistent across the page, the photos and the packaging.
Write for people, not just search engines
Searchable terms matter, since shoppers use specific words to find things. Use the name people would actually use for the item, once or twice, in the title and description where it is natural. Repeating the phrase over and over reads badly and does not help readers. Product pages benefit from the same attention to on-page SEO as any other page: a clear title, a unique description and descriptive image text.
Avoid copying the manufacturer’s description verbatim. It is often generic and the same text may appear on many other websites. Writing your own, based on real questions, tends to be more useful to the reader.
Cover the awkward bits
Buyers appreciate frankness about limits. Consider mentioning:
- Sizing quirks (“runs small; consider sizing up”).
- Colour differences between screens and real life.
- Items that need assembly, batteries or other purchases.
- Allergens, safety information or age guidance, where relevant. Rules on product information vary by country and category, so check requirements for your products and market.
- Lead times for made-to-order items.
This honesty can reduce disappointed customers and returns. It also keeps you aligned with honest advertising principles.
Support the description with other elements
Words are only part of a product page. Clear photos from several angles, a size guide, real customer reviews and visible delivery and returns information all answer questions that text cannot. Describing images with useful alt text helps people who use screen readers and keeps descriptions in sync with what is shown. Never fabricate reviews or testimonials.
Tone and voice
Match the way the rest of your brand sounds. A craft maker may write warmly and personally; a technical supplier may be direct and precise. Either can be useful, so long as the facts come first. Keep sentences short and avoid piling up adjectives.
Review checklist
Before publishing a description, check that:
- The first line says what it is and who it is for.
- Key specifications are present, correct and consistent with the images.
- The likely questions are answered, including limits.
- Claims are factual and supportable.
- What is included and excluded is clear.
- Care, delivery and returns information is easy to find.
- It reads naturally and avoids hype and filler.
- It is checked for typos, in particular in sizes and prices.
Keep improving
Customer questions are a free source of feedback. When people write in to ask something the page should have answered, add the answer. Returns reasons can show where descriptions mislead, even unintentionally. If you have enough traffic, you can compare alternative layouts, though results from small shops can be uncertain.
A useful product description feels like a knowledgeable assistant who answers honestly. It may not win every sale, and no wording can promise that it will, but it gives the right buyers what they need to say yes, and the wrong ones a chance to say no early.
