How to Write Product Descriptions That Sell (South Africa Guide)

Product descriptions act as your online sales representative. Since online shoppers cannot physically touch, feel, or see the item, a product description should inform, reassure, and persuade them to buy it. That’s why how you craft this “salesperson” can win or lose a sale.

With eCommerce growing in popularity, competition for online sales is becoming increasingly fierce. Writing product descriptions that highlight real benefits while building trust and credibility can help your store stand out amongst competitors, improving search discoverability and sales.

In this guide, you’ll learn how to write product descriptions that boost conversions. It also covers features, benefits, and how to optimise your copy for SEO and mobile search.

Why product descriptions matter more than you think

A product description is marketing copy that explains what an item is, how it works, and why it is worth buying. It typically includes features, specifications, benefits, and the value it provides.

A good product description matters because it convinces shoppers to buy. This copy reduces doubt by answering customer questions and helping prevent abandoned carts. Well-written descriptions are often keyword-rich, making items discoverable on search engines.

Features vs. benefits: What SA shoppers actually want

If you’re wondering “how to write a good product description”, the short answer is: focus on the buyer rather than the item itself. Customers want assurance that the product addresses their needs. A great way to speak directly to buyers’ needs is to connect features to specific benefits. Think about a customer’s pain points and describe how the product addresses them.

Tip: Instead of simply listing a feature (e.g., 12-hour battery life), highlight how it benefits the buyer (Enough battery power to get through the workday without hunting for a charger).

Here’s an example of what a feature vs. benefits differentiation may look like:

Note: Features still matter, especially for products where customers need specifications such as dimensions, materials, compatibility, or technical details before buying.

How to structure a product description that converts

Writing a product description is a delicate task, but it shouldn’t take hours simply for the sake of perfection. Create a repeatable formula you can follow for most products, so you don’t have to start from scratch each time you create a listing.

1. Write a clear product title

Your title should immediately tell shoppers what the product is. Include relevant details such as the brand, product type, model, size, colour, or key feature where useful. Avoid vague titles and unnecessary promotional language.

2. Open with the main benefit

Lead with the reason someone should want the product. Use the opening sentence to communicate the item’s biggest benefit or the problem it solves, rather than making shoppers search through paragraphs for relevant or useful information.

3. Use bullet points for key details

Make important information easy to scan by using bullet points for specifications, dimensions, materials, sizes, compatibility, included items, or other purchase considerations.

4. Finish with a clear call-to-action (CTA)

Tell shoppers what to do next, whether that means selecting a size, adding the item to their cart, or completing their purchase. Keep your CTA clear rather than relying on exaggerated urgency.

Make your product copy SEO-friendly

Product descriptions should naturally include terms shoppers use when searching. Focus on matching search intent rather than repeating the same keyword. Think about what a customer would search for when looking for your product, including specific long-tail keywords that describe its type, features, use or audience.

For example, instead of repeatedly using “water bottle”, phrases such as “750ml insulated water bottle” or “stainless steel water bottle for gym” can provide more specific context.

SEO also extends beyond the description itself. Use descriptive image alt text, include relevant product schema or structured data, and make sure your product title, pricing, availability and other product information are accurate and consistent. These elements can help search engines better understand your products and how they should appear in search results.

Accurate product information can also support visibility on Google Shopping, although product descriptions are only one part of a successful product listing.

Format descriptions for mobile shoppers

Make your descriptions easy to scan on a smartphone by using short paragraphs, bullet points, and clear headings. Put the most important benefit and information near the beginning, and remove unnecessary filler. A mobile-friendly description should help shoppers understand the product quickly without wading through large blocks of text.

How to write descriptions for different product types

• Physical products: Include practical details such as size, materials, dimensions, colours, specifications, compatibility and what is included. Explain how these features benefit the customer.

• Digital products: Explain what the customer receives, the format, how they access it, who it is for and what problem it solves.

• Services: Focus on the outcome and experience customers can expect. Explain what is included, who the service is designed for and any important conditions.

Before and after product description writing examples

Before: “Black backpack with laptop compartment. Made from durable material.”

After: “Keep your laptop protected on your daily commute with this durable black backpack. The padded laptop compartment provides added protection, while the spacious design gives you room for everyday essentials.”

The second version still includes the key features but connects them to practical customer benefits.

Avoid common product description mistakes

• Focusing only on features: Explain why important features matter to the buyer.
• Using vague claims: Replace phrases such as “high quality” with specific, useful information.
• Copying manufacturer descriptions: Adapt product copy to your audience and brand.
• Writing large blocks of text: Use short paragraphs and bullet points for easier scanning.
• Overusing keywords: Keep SEO terms natural and relevant.
• Leaving out important details: Include specifications customers need before purchasing.

FAQs about how to write a product description

What should a product description include?

A product description should explain what the product is, highlight its main benefits, provide relevant features and specifications, and give customers the information they need to decide whether to buy.

How long should a product description be?

There is no universal word count. Write enough to answer important customer questions without adding unnecessary information. Simple products may need less detail, while technical or expensive products may require more.

How do I make my products rank on Google Shopping?

Use accurate, relevant product titles and descriptions, along with complete product information, appropriate images, pricing, availability, and strong keywords. Avoid keyword stuffing, and make sure your product data meets Google’s requirements.

Should I write descriptions in first person or third person?

Either can work depending on your brand voice. First person can create a more personal tone, while third person may suit a traditional retail style. Whichever you choose, prioritise clarity and consistency.

Key takeaways for writing product descriptions that sell
