How to Write Product Descriptions That Sell

Product descriptions are one of the most underinvested areas of e-commerce. Many online retailers either copy descriptions directly from the manufacturer — which damages their SEO and differentiates them from no one — or write bare-minimum copy that lists a few features without explaining why any of them matter. Both approaches leave sales on the table.

A well-written product description does two jobs simultaneously. For the customer, it answers the question "Is this right for me?" by translating features into tangible benefits and painting a picture of what life looks like after purchase. For search engines, it provides unique, keyword-rich content that helps the product page rank for the terms potential buyers are searching for. Getting both right is achievable, and the impact on revenue can be significant.

Benefits Over Features

The most important principle in product copywriting is that customers buy outcomes, not specifications. A drill bit is not a product people want — what they want is a hole in the wall. A running shoe is not bought for its midsole cushioning foam — it is bought because the customer wants to run further without knee pain. Your product description should lead with the outcome the customer desires and support it with the features that deliver that outcome.

Features are facts about your product: what it is made of, how big it is, what it does technically. Benefits are what those features mean for the customer: why they matter, what problem they solve, what goal they support. "Made from merino wool" is a feature. "Stays fresh for days without washing, so you pack lighter on longer trips" is a benefit. Write descriptions that make this translation for the customer rather than leaving them to figure it out.

Write for Your Specific Customer

The most effective product descriptions are written as if addressing one specific person — your ideal customer. Before you write, consider who that person is. What do they already know about this product category? What words do they use when they search for it? What is their primary motivation for buying — saving time, looking impressive, solving a pain point, treating themselves? The language and emphasis of your description should reflect the answers to these questions.

Tone matters as much as content. A luxury brand and a value brand are not just selling different products — they are speaking to different customers who respond to different language. High-end customers respond to confidence, scarcity, and craftsmanship language. Value-focused customers respond to practical benefit, simplicity, and reassurance. A product description that sounds wrong for your brand will undermine trust even if the facts it contains are accurate.

SEO Considerations for Product Descriptions

Unique product descriptions are essential for e-commerce SEO. If you use the manufacturer's standard description, you are competing against every other retailer who has done the same — Google may see your page as duplicate content and deprioritise it in search results. Write original descriptions for every product, especially your best-sellers and highest-margin items.

Research the terms customers use to find your type of product and incorporate them naturally into your descriptions. A 150 to 300 word description provides enough content for search engines to understand what the product is and for whom it is relevant, without overwhelming the customer with text. Structure longer descriptions with bullet points for scannability — many customers scan before they read, and bullet points let them extract key benefits quickly.
