How to sell the same product on Amazon, Etsy, eBay and Shopify without rewriting it 4 times

You've got a product selling well on your Shopify store, and you want it on Amazon, Etsy and eBay too. So you copy the title and description, paste them into the first marketplace, and it's rejected for being too long. You trim it. The next site wants tags. The one after wants a different kind of description. By the third platform you're writing it from scratch again.

The problem isn't you. Each platform has its own limits and its own idea of a good listing. The fix is to stop treating any one listing as the original. Write a master fact sheet once, then build each platform's version from it.

Why one copy doesn't fit everywhere

Here's how the title rules alone differ, from each platform's own help pages (covered in more detail in our platform guides):

And it's not just titles. Amazon wants bullet points. Etsy wants 13 tags. Walmart wants a description written as one paragraph with no lists. Shopify depends on Google, so the meta description matters there and nowhere else. A single block of text can't meet all of those at once.

Step 1: write a master fact sheet

Before you write a single title, put every fact about the product in one place. A spreadsheet works, with one row per product:

• Product name and brand
• What it is, in the words a shopper would search
• Key details: size, weight, count, colours, materials, compatibility
• Who it's for and what it's used for
• Three to six benefits, each one sentence, each backed by a fact
• What's in the box
• Care, safety and warranty notes
• Main keywords you've researched, ranked from most to least important
• Claims you can't make, like certifications you don't hold

This is the slow part, but you only do it once. Every platform version below is just a rearrangement of these facts. When something changes, like a new colour or a price, you update the fact sheet and then each listing.

If you haven't done keyword research yet, our guides for Amazon keywords and Etsy keywords cover free methods. The words people search for on Etsy are often different from Amazon, so it's worth checking both.

Step 2: build each title from the same parts

Keep the same core (brand, product type, the most important detail), then add or drop details to fit each limit:

• Amazon: the shortest. Brand, product type and the one or two details that matter most, within 75 characters. Everything else goes into Item Highlights. See our guide to the 75-character title.
• eBay: 80 characters, so you can usually fit brand, type and three or four specifics like size, colour and model. Don't add words like "L@@K" or brand names you aren't selling. See our eBay title guide.
• Etsy: start with what the item is in plain words, then a few key details, and keep it readable. The extra search phrases go in your 13 tags, not the title. See our Etsy titles and tags guide.
• Shopify: the product title can be the friendliest version, because it's what shoppers see on your store. Write a separate page title for Google. See our Shopify product SEO guide.

Step 3: shape the description for each site

From the same facts:

• Amazon: turn your benefits into bullet points, most important first, and keep the product description for detail. Our bullet point guide shows how.
• Etsy: start with a short paragraph about the item and who it's for, then the details shoppers ask about: size, materials, care, personalization and processing time.
• eBay: item specifics do a lot of the work. Fill them in fully, then use a short description for condition and anything specifics can't cover.
• Shopify: write for a person who arrived from Google with a question, and add a meta description.
• Walmart and TikTok Shop have their own rules, covered in our Walmart and TikTok Shop guides.

Rewriting the order and length also avoids posting the same block of text everywhere, which reads as lazy to a shopper who sees it twice.

Step 4: check the rules each site adds

A few things catch sellers who cross-list:

• Etsy only allows certain items. Every listing has to meet Etsy's Creativity Standards: made by you, designed by you, handpicked by you (like vintage items 20 or more years old) or sourced by you (like craft supplies) (Etsy Creativity Standards). A product you resell wholesale may be fine on Amazon or eBay and not allowed on Etsy.
• Images differ. Amazon and Walmart want a white background on the main image. Etsy doesn't require one and lifestyle photos often do better there. Keep a white-background set and a lifestyle set.
• Brands and claims. If you aren't the brand owner on Amazon, or don't have approval for a claim on Walmart, the fact sheet should say so, so it doesn't slip into one version by accident.
• Stock. If you only have one of something, like a vintage piece, selling it on two sites at once is a real risk. Update stock quickly, or use a tool that syncs it.

Tools that can help

You don't have to copy and paste every listing by hand:

• Shopify sales channels. Shopify lets you connect marketplaces and social channels to your store and manage products from the Shopify admin. Amazon is one of the listed marketplaces, and others are available from third-party developers in the Shopify App Store (Shopify help: sales channels).
• Marketplace bulk upload. Amazon, eBay, Walmart and TikTok Shop all offer some form of bulk upload from a spreadsheet, which works well if your fact sheet is already a spreadsheet.
• Cross-listing apps. Third-party tools like Vendoo, List Perfectly and Crosslist copy listings between marketplaces, and are popular with resellers. Check their sites for which marketplaces they support and their pricing pages for costs.

Most of these copy the same text from one place to another. They save the posting work, but you still need each title and description to fit the platform it's going to.

A worked example

This is a made-up product to show the process. "Fernbrook" isn't a real brand.

Fact sheet: Fernbrook soy candle, 8 oz, cedar and sage scent, amber glass jar, cotton wick, about 45 hours burn time from the maker's testing, hand-poured in small batches, gift for housewarming.

Etsy tags then pick up the phrases the title doesn't carry, like "housewarming gift", "woodsy candle" and "small batch candle". On Amazon, the burn time and cotton wick go into Item Highlights and bullets. On Shopify, the meta description talks about the scent and the gift angle for people searching on Google.

Same facts, four listings, and none of them written from a blank page.

Where YelloShelf fits

The slow part is the rewriting. YelloShelf is a paid tool that drafts listings from your product photos and can give you versions for different platforms from the same product. It doesn't have a free plan or trial. You buy a credit pack, starting at $10, and your first purchase comes with a money-back guarantee. We're helping you remove the manual, tedious, time-consuming work. You still read it, edit it and paste it in yourself, on each platform, against that platform's rules.

Quick checklist

• One fact sheet per product with every detail, keyword and claim limit.
• Titles built from the same core, trimmed to each limit.
• Descriptions reshaped for each site: bullets, paragraphs, specifics or SEO.
• Etsy listings checked against the Creativity Standards.
• A white-background image set and a lifestyle set.
• Stock synced, especially for one-off items.
• Fact sheet updated first whenever something changes.
