How to Write Product Descriptions That Sell

Great product descriptions do more than describe. They persuade, overcome objections, and compel action. This guide shows you how to write copy that converts.

Why Descriptions Matter

In a physical shop, customers can pick up products, feel the materials, and ask questions. Online, your product description has to do all of that work. It must answer questions, address concerns, and create desire.

Many stores simply list features or copy manufacturer descriptions. This is a missed opportunity. Original, compelling descriptions differentiate your products, improve SEO, and significantly increase conversions.

What Product Descriptions Must Do

  • Inform: Provide essential details about what the product is and does
  • Persuade: Convince browsers that they need this product
  • Differentiate: Explain why your product is better than alternatives
  • Reassure: Address potential objections and reduce purchase anxiety
  • Rank: Help search engines understand and index your products

The ROI of Good Copy

Studies show that well-written product descriptions can increase conversion rates by 30% or more. For a store doing £100,000 per month, that improvement is worth £30,000 monthly in additional revenue.

Know Your Customer

Effective product descriptions speak directly to your ideal customer. Before writing, you need to understand who you are writing for.

Questions to Answer

  1. 1
    Who is your customer?

    Age, gender, occupation, lifestyle, values. The more specific, the better your copy will resonate.

  2. 2
    What problem are they solving?

    People buy solutions, not products. What need or desire does this product fulfil?

  3. 3
    What objections might they have?

    Price, quality, fit, durability. Address these proactively in your description.

  4. 4
    What language do they use?

    Technical jargon for enthusiasts? Simple language for casual buyers? Match their vocabulary.

Write to One Person

Even if you have many customers, write as if speaking to one person. Use "you" instead of "customers". This creates intimacy and makes your copy feel personal rather than corporate.

Features vs Benefits

The most common mistake in product descriptions is focusing on features instead of benefits. Features describe what a product is; benefits describe what it does for the customer.

Features vs Benefits Examples

Feature: Made from 100% merino wool

Benefit: Stays warm without overheating, naturally breathable for all-day comfort

Feature: 10,000mAh battery capacity

Benefit: Charges your phone 3-4 times before needing a recharge

Feature: Reinforced stitching

Benefit: Built to last years of daily use without falling apart

The FAB Formula

For each feature, use the Feature-Advantage-Benefit formula:

Feature

What it is (the fact)

Advantage

Why that matters (the function)

Benefit

What it means for the customer (the feeling)

Structure and Formatting

Online readers scan rather than read. Your description needs to be scannable whilst still delivering compelling copy for those who read in detail.

Ideal Description Structure

  1. 1
    Opening Hook

    One or two sentences that grab attention and state the main benefit. This is what scanners will read.

  2. 2
    Mini Paragraph

    A short paragraph (2-3 sentences) expanding on the key benefits and addressing the primary use case.

  3. 3
    Bullet Points

    4-6 bullets highlighting key features and their benefits. Scanners love bullet points.

  4. 4
    Technical Details

    Specifications, dimensions, materials, care instructions. Important but secondary information.

Formatting Tips

  • • Use short paragraphs (2-3 sentences maximum)
  • • Add white space to improve readability
  • • Bold key phrases for scanners
  • • Use subheadings to break up longer descriptions

Sensory Language

Since customers cannot physically experience your product, you need to create that experience through words. Sensory language activates the imagination and creates desire.

Engage Multiple Senses

Touch

"Buttery-soft leather that moulds to your feet", "Crisp cotton with a satisfying weight"

Sight

"Rich burgundy that deepens with wear", "A silhouette that flatters every figure"

Smell

"The subtle scent of genuine leather", "Freshly ground coffee aroma"

Sound

"A satisfying click when you close it", "Whisper-quiet operation"

Show, Do Not Tell

Instead of "high-quality leather", write "full-grain Italian leather that develops a unique patina over time". Specific, sensory details are more convincing than vague claims.

SEO Optimisation

Product descriptions serve dual purposes: persuading humans and ranking in search engines. The good news is that natural, helpful content tends to rank well.

SEO Best Practices

  • Include your primary keyword naturally in the first paragraph
  • Write at least 300 words to give search engines enough content to index
  • Use related keywords throughout (colour, material, style variations)
  • Write unique descriptions for every product (no duplicates or manufacturer copy)
  • Answer common questions that people search for

Do Not Keyword Stuff

Write for humans first. Awkward, keyword-stuffed descriptions hurt both conversions and rankings. If a sentence sounds unnatural with your keywords, rewrite it.

Common Mistakes

Avoid these common product description mistakes that hurt conversions.

Using Manufacturer Descriptions

These are duplicated across the internet, hurting your SEO. They are also typically boring and feature-focused rather than benefit-focused.

Being Too Short

One-sentence descriptions do not provide enough information to make a purchase decision. Aim for at least 150-300 words.

Focusing Only on Features

Features tell, benefits sell. Always translate features into customer benefits.

Generic Language

"High quality", "best in class", "premium" are meaningless without specifics. Show quality rather than claiming it.

Ignoring Objections

If customers commonly return items or ask questions, address those concerns proactively in your descriptions.
