Writing product listings people actually order from
A customer decides in about four seconds. Most listings spend those seconds badly.
A customer scrolling a list is not reading. They are scanning, and they will decide about your item in roughly the time it takes to pass it. Everything about a good listing follows from that.
Name the thing, then qualify it
Put the recognisable noun first. "Jollof rice with chicken" beats "Special house combo". A customer searching for jollof will not find your special house combo, and a customer scanning will not stop at it.
Qualifiers go after: size, quantity, variant. "Bag of rice, 5kg" rather than "5kg quality rice bag offer".
Sizes and quantities are not optional
The most common reason a customer does not order is that they cannot tell what they are getting. How many pieces. What weight. Whether it serves one or three.
An item without a quantity is a question, and a question in a list is usually a skip.
Prices that match reality
The price shown is the price the customer expects to pay. If your in-store price changes, change the listing. A customer who discovers a different total has learned something about your store that no discount will unlearn.
Photographs
One clear photograph of the actual item, in daylight, taken from the angle a customer would see it. Not a stock image of something similar. Not a photograph with your whole counter in it.
If the item looks different in the photograph from how it arrives, you will get a complaint, and it will be a fair one.
Categories
Put items in the category a customer would look in, not the one that makes sense in your stockroom. This sounds obvious and is the most commonly ignored rule in any catalogue.
Keep the list honest
Remove what you do not have. A catalogue that lists things you cannot supply generates orders you must cancel, and cancelled orders cost far more than the missing listing would have.
The most effective catalogue we see is usually the shortest one that is completely true.
