How to write product descriptions that sell
A simple, practical method for writing product descriptions that answer shoppers’ questions, build trust and turn browsers into buyers, with examples.

A product description that sells answers the shopper’s questions before they ask them. Lead with who it’s for and what it does for them, back it up with specific details, make it easy to scan, and remove the doubts that stop people buying: size, fit, compatibility, delivery and returns. Write in plain words, for one real customer, and cut anything that doesn’t help them decide.
Start with your customer, not the product
Before you write a word, picture one person who buys this product. What problem do they have? What are they comparing you with? What would make them hesitate?
- Read your customer emails and reviews. The words customers use are the words to use back.
- Look at questions people ask before buying. Each one is a gap in your description.
- Look at returns. If people send things back because they’re “smaller than expected”, your page needs clearer sizes.
- Check what search phrases bring people to the page, if you have that data.
Features vs benefits
A feature is a fact about the product. A benefit is what that fact means for the shopper. You need both: the benefit makes people want it, the feature makes them believe it.
- Feature only
- “1,200mAh battery.”
- Benefit only
- “Lasts for ages.”
- Both together
- “Goes about a week between charges with daily use, thanks to a 1,200mAh battery.”
A simple test: after each feature, ask “so what?” Your answer is the benefit.
A structure that works
Most good product pages follow a similar shape. You don’t need to follow it rigidly, but it’s a reliable starting point.
- Opening line. One or two sentences: what it is, who it’s for and the main reason to buy. Many shoppers read nothing else, so make it count.
- Key benefits. Three to five short bullet points, each starting with the benefit and backed by a fact.
- The detail. A short paragraph or two for people who want more: how it works, what makes it different, how to use it.
- Specifications. Sizes, weights, materials, compatibility, what’s in the box. A simple list or table.
- Reassurance. Delivery time, returns, guarantee, care instructions. Answer the “what if” worries.
Be specific
Vague words like “high quality”, “premium” and “amazing” don’t persuade anyone, because every shop says them. Specific details do the work instead.
- Instead of “durable”, say what it’s made of and how it’s been tested.
- Instead of “compact”, give the measurements and compare it to something familiar: “about the size of a paperback”.
- Instead of “easy to use”, describe the steps: “one button, and the reading shows in about 30 seconds”.
- Instead of “fast delivery”, give the actual delivery time.
Make it easy to scan
People skim product pages, especially on phones. Help them find what they need quickly:
- Short paragraphs of one to three sentences.
- Bullet points for benefits and specs.
- Bold the few words that matter most, not whole sentences.
- Use clear subheadings if the description is long, such as “What’s in the box” or “Sizing”.
- Put the most important information first. Don’t bury the delivery time at the bottom.
Answer the doubts that stop people buying
Most lost sales aren’t because someone didn’t like the product. They’re because a small doubt wasn’t answered. Common ones:
- Will it fit? Size guides, measurements, “fits arms 22–42cm”.
- Will it work with what I have? Compatibility lists, models, plug types.
- When will it arrive? A clear delivery estimate on the page.
- What if I don’t like it? Your returns window and how easy it is.
- Is this shop real? Reviews, contact details, guarantee.
Questions-and-answers sections on product pages are a good way to handle the rest. Each question a customer asks once can be answered for everyone.
Write like you talk
Read your description out loud. If it sounds like a brochure, rewrite it as if you were explaining the product to a friend in your shop. Use “you”. Use short sentences. Avoid jargon unless your customers use it themselves.
- Brochure
- “This innovative solution delivers unparalleled comfort for discerning users.”
- Human
- “The padded cuff is soft enough to wear for a few minutes without pinching.”
Don’t forget search
Your product description also helps people find you on Google. You don’t need to stuff in keywords, but do:
- Use the words people actually search for, such as “upper arm blood pressure monitor” rather than a made-up product name alone.
- Write your own description. Copying the manufacturer’s text means your page looks the same as dozens of others.
- Write a clear product title that says what the product is.
- Add descriptive alt text to images.
Use photos and description together
Words and pictures should work as a team. If the description says “fits in a handbag”, show it in a handbag. If it says “clear display”, show the display close up. Each key benefit should ideally have a photo that proves it.
Getting it done when you have lots of products
Writing great copy for a big catalogue takes time. Start with your best sellers and the products with the most traffic, then work down. A template for each product type keeps things consistent. AI writing tools can help with first drafts; Merchella, for instance, has an AI writing help button on its fields. But always edit the result so it’s accurate, specific and sounds like you.
A quick checklist
- Does the opening line say what it is, who it’s for and why to buy?
- Is every benefit backed by a specific fact?
- Can someone skimming on a phone get the key points in ten seconds?
- Are size, compatibility, delivery and returns answered?
- Is every claim true and provable?
- Does it sound like a person wrote it?
In short
Great product descriptions are clear, specific and honest. Write for one real customer, pair benefits with facts, make it easy to scan and answer the doubts that stop people buying. Then watch your questions and returns, and keep improving the page.
