How to choose a marketplace
Five questions that settle the shortlist before you invest in feeds, photography and stock.
Start where your buyers already shop
Reach beats everything else. Amazon and eBay sell in almost every market, bol.com owns the Netherlands and Belgium, Walmart is United States only, and Zalando is European fashion. Pick the platform your buyers already open, not the one with the biggest global headline number.
Match the platform to your assortment
Every marketplace has a shape it rewards. Etsy is built for handmade, vintage and made-to-order. Zalando and ASOS Marketplace expect fashion data down to silhouette and size. Google Shopping sends traffic to your own webshop rather than hosting the sale. A catalog that fights the platform never ranks.
Count the work before you commit
Compare required fields, category depth and whether you need approval to sell. Amazon lists 18 required fields against a taxonomy eight levels deep; bol.com asks for 12 in a shallower tree. That gap is weeks of enrichment work, not an afternoon.
Check how your data gets in
An API means stock and prices sync automatically; a file-only channel means someone uploads a spreadsheet every week. ASOS Marketplace is CSV and manual entry, Amazon and bol.com sync near real time. The integration path decides how many SKUs you can realistically maintain.
Model the margin, not the reach
Commission, fulfilment and advertising costs differ per platform and per category, and they change. Read the marketplace's own current fee schedule, apply it to the products you would actually list, and only then decide. A channel that sells well at a loss is still a loss.

Region, fit, listing effort and integration path for every platform we document — so you can shortlist in one screen.
Listing effort is our own assessment, based on each platform's required-field count, category depth and approval process — the details behind it are in each guide. Fees and commission change often, so check the marketplace's own current rates before you decide.
What Are Marketplace Listing Guides?
Marketplace listing guides document the exact requirements, specifications, and best practices for listing products on major e-commerce platforms. Every marketplace has its own rules for product titles, descriptions, images, pricing, and feed formats. Sellers who follow them get their products approved and visible faster.
Our guides cover the full range of marketplace requirements: from mandatory fields like product titles and GTINs, to feed format specifications (XML, CSV, API), category mapping, and optimization strategies that improve visibility and conversion rates.
Whether you sell on one marketplace or ten, these guides give you a single reference for each platform so you can prepare your product data correctly from the start and avoid costly listing rejections.
Why Marketplace Listing Optimization Matters
More product visibility
Products with complete, optimized listings rank higher in marketplace search results. Our guides show you exactly which fields affect ranking on each platform.
Avoid listing rejections
Every marketplace enforces strict data quality rules. Knowing what's required upfront prevents costly rejections and suppressed listings that hurt your sales.
Higher conversion rates
Well-structured product data with compelling titles, detailed descriptions, and high-quality images directly increases click-through rates and purchases.
Multi-channel efficiency
Use a consistent product data structure that works across every marketplace. Our guides help you build one master catalog that feeds all your sales channels.
Common Marketplace Listing Mistakes
Avoid these frequent errors that cause listing rejections and poor product performance.
Using generic or keyword-stuffed product titles
Follow each marketplace title formula: Brand + Product Type + Key Attributes + Size/Color
Submitting low-resolution or watermarked images
Use 1000x1000px minimum, white background, no text overlays, following each marketplace's image guidelines
Missing or incorrect GTINs/EANs
Verify all barcodes against the GS1 database before submission. Apply for a GS1 prefix if you sell private label products.
Using identical listings across all marketplaces
Tailor titles, descriptions, and keywords to each marketplace's search algorithm and category requirements
Not mapping products to the correct marketplace category
Use each marketplace's category tool to find the most specific category. Avoid broad parent categories.
Not monitoring or updating listings after the first submission
Review listings monthly, update pricing in real-time, and refresh content seasonally for better ranking
