Marketplace listing copy

What marketplace listing copy is

Marketplace listing copy is the text you supply to somebody else's shop: the title, the bullet points, the description, the attribute fields and the back-end terms on Amazon, Etsy, a distributor's portal, or a national retailer's vendor system. It is written to fit a form. Each field has a character limit, each platform has a list of things you may not claim, and the page it appears on belongs to them.

It is not the same writing as your own site. A product description on your Shopify store can be any length, can link anywhere, can mention your guarantee and can point at a guide. A marketplace listing usually cannot do any of those things. It is also not advertising copy, which is bought placement. This is the free listing, and it is governed by rules you had no part in setting.

When you need it

You need it when you are opening on a marketplace for the first time and have been told to “just paste the website copy in”. It will not fit, and several sentences of it will trip a rule. You also need it when you already sell on one and the listings were written years ago by a supplier, a virtual assistant, or whoever set up the account.

The third case is a wholesale business being onboarded by a retailer. The vendor portal wants a title in their exact format, a set number of bullets, attribute values from their controlled list, and a brand paragraph, all by a deadline. That is a formatting and compliance job with writing inside it.

You do not need this if you sell on one platform only and the listings already convert. And if the products themselves are poorly described everywhere, the cheaper starting point is writing the descriptions properly on your own site first, then adapting.

Writing inside someone else's rules

The work is mostly constraint. Nobody finds it glamorous and it takes longer than free-form writing.

• The title, to the character. Each platform wants a different structure, usually brand, product, key attribute, quantity, in an order they specify. It is often the only text a shopper reads, and it gets truncated differently on a phone.
• Bullets that survive truncation. The first few words of each bullet carry the point, because the rest may be cut or hidden behind a link.
• Claims removed. Health, safety, environmental and comparative claims are restricted differently on every platform. “Best”, “guaranteed”, anything about treating a condition, and most references to your own website will get a listing suppressed.
• Attribute fields filled properly. The dull structured data: material, dimensions, compatibility, quantity. These decide which filters your product appears under, which is how most marketplace shoppers narrow a category.
• The same facts as your own page. Sizing and what is in the box, stated identically, because a customer who buys on a portal returns to the same warehouse.

What you get

A listing sheet per platform. One tab per marketplace, one row per SKU, every field in its own column with the character count shown against the limit, ready to paste or upload.

A rules note. A short document recording the limits and prohibited claims I worked to for each platform, with the date I checked them. When a listing is rejected in eight months, this is what you compare against.

A pattern for new products. The title formula and bullet structure per platform, written down, so your own people can list the next arrival without guessing.

A worked example

An illustration. A small-batch soap and candle maker in Guelph sells through her own Shopify store, an Etsy shop, and has just been accepted by a regional grocery chain's online vendor portal. The website copy runs to three hundred words per product and is full of language about what the ingredients do for skin.

Three versions get written for each of thirty products. The Etsy listings use the full title length with the material and scent that people search within the platform, and the description is restructured so the first two lines carry the point, because Etsy hides the rest behind a tap. The grocery portal allows sixty characters for a title and four bullets of eighty, wants net weight in the attribute field, and forbids every skincare claim on the site, so those sentences are rewritten as descriptions of the ingredients rather than statements about results. The rules note records that the portal's claim list was checked in March, because it will change. Nothing is invented; the same facts are said three ways at three lengths.

How it runs

1. A half-hour call. Which platforms, how many SKUs, and what has already been rejected or suppressed. No charge.
2. Access to the rules. You forward the seller guidance or vendor style guide for each platform. I read them before quoting, because they determine the work.
3. A fixed price in writing. Per SKU, per platform, with the first platform priced higher than the second, agreed before anything starts.
4. A pilot of five. Five products across every platform, five working days. You upload them and confirm nothing is rejected before the rest is written.
5. The full set, in batches. Delivered by platform so you can list one channel while the next is written.
6. Handover. The sheets, the rules note and the pattern document.

What it costs

Marketplace listings are quoted as a fixed price in CAD after the half-hour call, priced per SKU per platform. The second platform costs less than the first because the facts are already assembled; only the fitting is repeated. How many products, how many channels and how strict each portal's guidance is all move the number, which is fixed in writing before anything starts. The pricing page explains how quotes are built here.

What happens next

Two things are worth remembering about this work. You do not own the page, so a platform can change its layout, its limits or its claim rules without telling you, and listings that were compliant last year quietly stop being so. Most sellers put a reminder in the calendar to re-read the guidance once a year against the rules note. The second is that the parcel is the one surface in a marketplace sale that is entirely yours, which is why sellers move next to the words on the box and the insert card. The questions that cause returns need the same treatment on every channel, as answers written before the sale, and portals that ask for a company paragraph are best served by an agreed boilerplate description rather than something written fresh each time. Each is a separate piece of work. The listings are complete on their own.
