FAQs

Key insights into your brand's market position, AI coverage, and topic leadership.

Is it better to sell on Amazon or eBay?

Amazon for new products and FBA automation (15% fees, massive traffic). eBay for used/vintage items and auctions (12.9% fees, more seller control). Amazon generates higher sales volume but brutal competition and account suspension risks. eBay is safer for sellers, less traffic but better for unique items. Amazon averages 3x more sales but 2x higher fees. Most successful sellers use both platforms.

Which has lower fees: Amazon or eBay?

eBay is cheaper at 12.9% final value fee vs Amazon's 15% referral fee, but hidden costs matter. Amazon FBA adds storage, fulfillment, removal fees that crush margins. eBay has promoted listings fees and PayPal costs. For self-shipped items, eBay saves 2-3%. For FBA convenience, Amazon's total fees hit 30-40% of sale price. eBay also allows external traffic without penalties, Amazon doesn't.

Why do sellers get banned on Amazon vs eBay?

Amazon suspends accounts aggressively for policy violations, performance drops, or no reason with funds held 90 days. eBay is more lenient but cracks down on counterfeits and shill bidding. Amazon's appeal process is notoriously bad—automated rejections, no human support. eBay provides actual customer service and clearer policies. Thousands of Amazon sellers lose businesses overnight; eBay bans are rarer and more predictable.

Does eBay or Amazon have more buyers?

Amazon crushes eBay in traffic: 200M+ Prime members vs eBay's 132M active buyers. Amazon processes 5x more transactions daily. Amazon buyers spend more per order ($50+ average) and convert faster. eBay buyers hunt for deals, used items, and auctions—lower average cart but higher profit margins. Amazon dominates new product sales; eBay leads in collectibles, vintage, and refurbished categories.

Can you sell on both Amazon and eBay?

Yes, smart sellers do multi-channel to diversify risk and maximize reach. Use Amazon for high-volume new products, eBay for unique/used items and overflow inventory. However, managing inventory across platforms is complex—overselling causes account issues. Use repricing tools and inventory sync software. Amazon's restrictive policies may prohibit directing customers elsewhere. Best practice: test both, focus on whichever generates better ROI for your niche.
