How to Write Product Descriptions That Actually Help Buyers Decide
A good product description answers the buyer's real question before they even think to ask it. Here's how to write one that works.
Start With the Buyer's Question, Not the Product
Most product descriptions describe the product. That's the wrong starting point. The buyer isn't thinking 'what is this?' — they're thinking 'will this work for me?' Start there.
Think about the specific situation your buyer is in when they land on your page. A stationery seller in Mong Kok might assume buyers know what washi tape is. Many don't. Others know exactly what it is but want to know if the adhesive leaves marks on textured walls. Those are two different descriptions.
Lead With What It Does for Them, Not What It's Made Of
'Made from 304 stainless steel with a brushed finish' tells the buyer what the product is made of. 'Stays rust-free after years of daily dishwashing' tells them what that means for their life. Both facts matter, but the second one closes the sale.
List features only after you've established why they matter. Link each spec to a real benefit. If a feature doesn't change anything for the buyer, cut it.
Handle the Doubt Before It Becomes a Reason to Leave
Every buyer has a silent objection. For food products, it might be 'is this suitable for kids?' For custom items, 'how long will shipping take?' For software, 'what if I'm not tech-savvy?' These doubts often go unaddressed — and that's when buyers close the tab.
You don't need a FAQ for every product. Sometimes one sentence handles the most common objection directly: 'Ships from our Kwun Tong workshop — local Hong Kong orders typically arrive in 2 business days.' Specificity builds trust faster than reassurances.
Format for the Way People Actually Read Online
Online shoppers scan before they read. A wall of text loses them at the first glance. Break the description into short paragraphs. Use a bullet list for key specs — five bullets maximum. Put the most important point first in every paragraph.
Watch your character count on mobile. In Hong Kong, most shoppers browse on their phones. Long sentences that wrap awkwardly on a small screen slow the reader down. Read your description aloud on your own phone before publishing.
Treat Every Description as a First Draft
Track which products get 'add to cart' clicks and which don't, even at the same price point. When a product underperforms, rewrite the description before changing anything else — it's the lowest-cost test available.
Ask real customers what question they had before buying. Their exact words often become the strongest opening line for a description.
Common questions
How long should a product description be?
Long enough to answer the buyer's main question and handle one or two doubts — short enough to read in under a minute. For simple products, three sentences may be enough. For technical or high-priced items, a few short paragraphs plus a spec list works well. There is no universal word count.
Can I use the same description on my website and on marketplace platforms?
Ideally not. Platforms like Carousell or HKTVmall have their own search algorithms, character limits, and buyer expectations. Your own website gives you full control over format and tone. Write one solid version first, then adapt it for each channel — the core message stays the same, but length and structure may differ.
Do I need to include SEO keywords, and will that hurt readability?
You need both — and they're not opposites. Write for the reader first, then check whether your natural language already includes the terms buyers search for. If it doesn't, add them where they fit naturally. Forcing keywords into awkward sentences damages both readability and rankings.
I have dozens of products — how do I scale this without starting from scratch each time?
Build a simple template with four prompts: what problem does this solve, what's the key outcome, what are the top three specs, and what's the main doubt to address. Fill it in for each product. After ten descriptions, patterns emerge — your product categories develop a consistent voice, which makes future writing faster.
