How to Write Product Descriptions That Convert

Find out what actually stops people

Before writing anything, collect the real questions: from support, from reviews, from the returns reasons, from what customers ask before buying.

Those questions are the description. Sizing, compatibility, what is in the box, how long it lasts, whether it works with the thing they already own. Every unanswered one is a reason to leave and check a competitor who did answer it.

Returns data is the most underused source here. People return things when the description let them believe something untrue.

The structure

Four parts, in order, and length driven by price rather than by preference.

• One or two sentences on what it is and who it suits, in plain language
• The three to five things that actually matter, each tied to why it matters
• Full specifications, in a scannable list, for the people who came for exactly that
• The objections: sizing, compatibility, care, delivery, returns

Features and benefits, without the cliche

The advice to write benefits not features is half right and often produces vague copy.

Buyers of considered products want the specification. What they do not want is a specification with no interpretation. Give both: the number, then what the number means for them.

Water resistant to a stated depth, which means you can swim in it but should not dive. That is a feature and a benefit in one sentence, and it prevents a return.

Duplicate content, and why manufacturer copy hurts

If you sell products others also sell, the supplied description is on hundreds of pages. Search engines will show one of them and it will usually be the largest retailer.

Writing your own is the only fix, and it is also where you can be genuinely better: your photos, your honest note on who it is wrong for, your comparison with the other item you stock.

For a catalogue too large to rewrite entirely, prioritise. Rewrite the products that already get impressions and the ones with the highest margin, and leave the long tail until they matter.

Writing at scale without sounding generated

For large catalogues, a template plus real variation works. The failure is a template with only the product name swapped, which is thin content by definition.

The variation has to be substantive: the specific use, the specific limitation, the specific comparison. If you cannot write two genuinely product-specific sentences, the page will not earn a ranking however it is generated.

Length

Match the length to the size of the decision. A low-priced accessory needs a few lines. A considered purchase needs everything a buyer would otherwise search for elsewhere.

Put the essentials above the fold and the depth below it. The scanner and the researcher are both real customers and the page has to serve both without making either scroll past the other's content.
