How to Write Product Descriptions That Actually Sell
· By Twisty Designs
Most product descriptions do one thing: describe the product.
They list the size, the material, the weight, the dimensions. They tell the customer what the product is. And then they wonder why the customer clicks away without buying.
The best product descriptions do something completely different. They make the customer feel something. They paint a picture of what life looks like with the product in it. They answer the questions the customer is silently asking and remove every reason not to buy.
If your Shopify store has traffic but low conversion rates, your product descriptions are often the first place to look. Here is how to write them properly.
Start With Your Customer, Not Your Product
Before you write a single word, get clear on who is reading the description and what they actually care about.
A customer buying a personalised gift for their mother is not thinking about thread count or print resolution. They are thinking about whether their mum will cry when she opens it. They want to feel confident they are giving something meaningful, something that will be kept and treasured, not something generic that gets put in a drawer.
A customer buying a custom hoodie for their sports team is not thinking about GSM weight. They are thinking about whether the team will love it, whether the colours are right, and whether it will arrive before the next game.
Lead With the Benefit, Not the Feature
Features describe what a product is or has. Benefits describe what it does for the customer. This distinction is the single most important concept in writing product descriptions that sell.
Feature: "Made from 350GSM premium cotton."
Benefit: "Thick enough to keep out a winter chill, soft enough to wear all day."
Feature: "Personalised with your chosen name or message."
Benefit: "A gift they will never find in any shop, made just for them, with the words that matter most."
Features belong in your descriptions. They provide the practical information customers need to make a confident decision. But they should support the benefit, not replace it. Lead with what the product does for the customer, then back it up with the specifics.
Write the Way Real People Talk
Read your product description out loud. If it sounds like a catalogue or a press release, rewrite it.
Good product copy sounds like a knowledgeable friend talking to you about something they genuinely love. It uses the same words your customer uses. It is warm, direct, and confident without being pushy.
Avoid corporate language, filler phrases, and vague superlatives. "High-quality", "premium", and "exceptional" mean nothing without evidence. Instead of saying the quality is exceptional, describe something specific that proves it. Instead of calling something luxurious, describe the texture, the weight, the way it feels.
Specificity is what builds trust. Vagueness creates doubt.
Answer the Questions Before They Are Asked
Every customer reading your product description has a list of questions running through their mind. Will this fit? What does it actually look like? How long will it take to arrive? What if I do not like it? Is this the right gift?
Your job is to answer those questions before the customer has to go looking for answers elsewhere. Because the moment they have to go looking, most of them will not come back.
Think through every question a new customer might have about your product and make sure the description, the images, and the surrounding page content address them clearly. Include size guides, personalisation examples, turnaround times, and anything else that removes uncertainty.
Uncertainty is the enemy of conversion. The more confident a customer feels, the more likely they are to buy.
Use Sensory Language to Make Products Feel Real
Online shoppers cannot touch, smell, or try your products before they buy. Your job is to close that gap as much as possible through words and images.
Describe how things feel. Describe how they look in real light, not just in a product photo. Describe the experience of using or wearing or giving the product. Help the customer imagine themselves with it.
"The mug arrives in a gift-ready box, ready to give exactly as it comes. Hold it and you will feel the weight of something made to last. The print is sharp and vivid, exactly as you designed it, exactly as they will remember it."
That kind of writing puts the product in the customer's hands before they have even added it to their cart.
Write Different Descriptions for Different Products
Not every product needs the same length or the same approach.
A simple, everyday product might need only two or three sentences. A personalised, high-emotion gift needs more space to tell its story. A technically complex product needs clear, structured information with specifications that matter.
Match the length and format of your description to what the product and the customer actually need. Long for the sake of long is not better. Short and powerful always beats long and padded.
As a general guide: write enough to make the customer feel completely confident and excited to buy, then stop.
Optimise for Search Without Killing the Copy
Good product descriptions also help customers find your store through Google. Including the right keywords naturally in your copy helps your pages rank for the search terms your customers are actually using.
The key word here is naturally. Stuffing keywords into descriptions in a way that reads awkwardly damages both your customer experience and your search rankings. Write for the customer first, and include relevant search terms where they fit naturally into the language you are already using.
For personalised and custom products, focus on the occasion and the recipient as well as the product itself. Customers often search for "personalised birthday gift for mum" rather than the specific product name. Your description should speak to that intent.
For Personalised Products: Sell the Moment, Not Just the Object
If you sell personalised or custom products, you have an advantage most product sellers do not: emotion.
A custom print is not a print. It is the moment someone sees their name in lights for the first time. It is a memory turned into something you can hold. It is a gift that says "I thought specifically about you" in a way a generic present never can.
When you sell personalised products, your description should spend as much time on the moment and the feeling as it does on the product itself. Describe who gives it and who receives it. Describe the look on their face. Help the customer see themselves giving this gift and the reaction it creates.
This is what makes personalised product descriptions so powerful: they are not really about the product at all. They are about the person, the occasion, and the connection.
