A product description has one job: answer the question that is stopping this shopper from buying. Most descriptions answer a different question, usually "what is this?", which the photo already answered. Below is a five-part formula, eight before and after examples across different kinds of products, and the claims to leave out.
The five-part formula
- Outcome first. One sentence on what changes for the buyer. Not "premium stainless steel water bottle" but "cold water at your desk at 4 pm."
- The doubt, answered. Every product has one main objection: will it fit, will it last, is it worth the price, will it arrive in time. Name it and answer it.
- Specifics a photo cannot show. Dimensions, weight, materials, what is in the box, care instructions.
- Proof. A number you can stand behind, a guarantee, a return window, or how many people have bought it. Only what is true.
- The next step. Shipping time, return policy, or a size note, placed right before the button.
Not every product needs all five at the same length. A $9 phone case needs two lines; a $400 chair needs all five.
Eight examples, before and after
1. A water bottle (objection: will it really keep drinks cold?)
Before: Premium double-wall stainless steel water bottle. Leak-proof lid. BPA free. Available in 6 colors.
After: Fill it with ice water at 8 am and it is still cold at your 4 pm meeting. Double-wall vacuum insulation, a lid that does not leak in a bag, and a mouth wide enough for ice cubes. 24 oz, fits standard car cup holders. Hand wash only: the dishwasher dulls the coating.
Why it works: it answers "does it actually work" with a situation, then gives the two facts a buyer checks (size, cup holder fit) and the one they will regret not knowing (hand wash).
2. A graphic t-shirt (objection: will it fit and will the print last?)
Before: Soft and comfortable unisex tee with a unique design. Makes a great gift!
After: Unisex fit, true to size: if you are between sizes, size up for a relaxed look. The print is direct-to-garment, which keeps it soft to the touch. Wash inside out in cold water and it stays sharp. Printed to order and shipped in 3 to 5 business days.
Why it works: fit and how the print holds up are the two things a shirt buyer cannot judge from a photo. "Great gift" says nothing a shopper can check.
3. A handmade candle (objection: is it worth the price?)
Before: Hand-poured luxury soy candle with essential oils. Long burn time.
After: About 50 hours of burn time from 8 oz of soy wax, poured in small batches. Scent: cedar and orange peel, noticeable across a living room without being heavy. Trim the wick to a quarter inch before each burn for an even melt.
Why it works: "long burn time" becomes a number, and the scent description tells the buyer how strong it is, which is the real question behind "luxury."
4. A pet bed (objection: what size does my dog need?)
Before: Ultra-comfortable orthopedic dog bed for dogs of all sizes.
After: Measure your dog from nose to base of tail while lying down, then add 8 to 12 inches. Medium (30 x 24 in) fits most dogs up to 40 lb; large (36 x 28 in) up to 70 lb. The cover unzips and goes in the washing machine; the foam does not.
Why it works: a size guide inside the description answers the question that decides whether the bed fits, before the order instead of after it.
5. A skincare product (objection: will it suit my skin?)
Before: Our miracle serum transforms your skin overnight with clinically proven ingredients.
After: A lightweight serum with 5% niacinamide for oily and combination skin. Use morning and night after cleansing, before moisturizer. If your skin is sensitive, start every other day for the first week. 30 ml lasts about two months with daily use.
Why it works: it says who it is for and how to use it. "Miracle" and "clinically proven" are claims a store has to be able to back up, which is a legal problem, not a copywriting one (see below).
6. A digital download (objection: what exactly do I get?)
Before: Beautiful printable planner to organize your life!
After: 42-page PDF: a yearly overview, 12 monthly spreads, weekly pages and 6 habit trackers. Prints on US Letter or A4. Instant download after checkout; nothing is shipped.
Why it works: digital buyers cannot touch the product, so the contents list is the product.
7. A gift item (objection: will it arrive in time and look good?)
Before: The perfect gift for any occasion.
After: Arrives in a kraft gift box with tissue, ready to hand over. Add a message at checkout and we print it on a card inside; the price never appears in the package. Order by December 15 for delivery by December 24 in the continental US.
Why it works: for a gift, presentation and arrival date are part of the product. (Set the date to your real cutoff.)
8. An expensive item (objection: what if I do not like it?)
Before: Ergonomic office chair designed for all-day comfort.
After: Adjustable lumbar support, seat depth and armrest height, so it fits people from about 5'2" to 6'4". Try it for 30 days; if it is not right, we pick it up and refund you. Arrives mostly assembled: attaching the base and arms takes about 10 minutes.
Why it works: at a high price the return policy is the description. Put it where the doubt is, not only in the footer.
Claims to leave out unless you can prove them
- "Made in USA." The FTC's standard for an unqualified Made in USA claim is that the product is "all or virtually all" made in the US, including final assembly, all significant processing and almost all components. A shirt printed in the US on an imported blank does not meet it. The FTC's Labeling Rule covers online marketing materials that show a Made in USA seal or label, and marketers can face civil penalties. A qualified claim such as "Printed in the USA on an imported blank" is the FTC's suggested route, as long as it is true and does not suggest the whole shirt is American-made.
- Health and results claims. "Clinically proven," "cures," "removes wrinkles" and similar promises need competent and reliable scientific evidence, which is the standard in the FTC's Health Products Compliance Guidance.
- Superlatives you cannot measure. "Best," "softest" and "highest quality" give a shopper nothing to check, so they rarely do any work.
- Invented urgency. A countdown that resets on every visit is easy to catch, and once a shopper catches it, the rest of the page is doubted too.
How to find your product's main objection
The examples above each start from one objection. To find yours, read your returns and refund reasons, the questions customers email before buying, and the one-star reviews of competing products. The objection that shows up most is the one your description should answer in its first two lines.
If you have no sales yet, you have no returns to read. That is the gap PageJury fills: 50 AI shopper personas read your product page and each one says what stopped them. The sample report shows what that looks like, and the six objection types explains how to read it. For the rest of the page, use the product page checklist.
FAQ
How long should a product description be?
As long as it takes to answer the main doubt and give the facts a photo cannot. That is two or three lines for a simple, cheap product and several short paragraphs for an expensive or technical one.
Should I use bullet points?
Yes, for specifications: dimensions, materials, what is in the box. Use a sentence or two of normal text for the outcome and the objection, which read better as prose.
Can I copy the manufacturer's description?
You can, but every other store selling the same product has it too, so it does nothing to set yours apart. Rewrite it around the objection your buyers have.
