Ideas of what to sell on eBay

One of the joys of online marketplaces is the sheer breadth of choice and diversity of items you can buy and sell there. But to be really successful, it’s probably best to narrow down what you want to sell. What are your passions? The things you’re most interested are likely to drive your best sales.

Most people who sell items online tend to sell second-hand clothes (55%). Other popular items include new clothes or shoes (32%), games and toys (29%), children’s clothes or toys (25%) and second-hand tech (24%).

If you’re unsure where to start, these categories might help.

• Used or vintage items: great if you have lots of things to clear out from your home. Also ask family and friends for unwanted, pre-loved items. Or visit flea markets, car boot fairs and vintage shops to source pre-owned clothing, electronics, homewares and collectables
• Brand new products: you can get these direct from wholesalers or manufacturers and become the liaison between them and their customers. This option works particularly well for electronics, fashion and handmade items
• Unique crafts: one-off or small batch products such as handmade jewellery, artwork and personalised items are another popular area with sellers and customers alike
• Rare and collectable items: online marketplaces are a great place for collectors to find those rare, must-have treasures. Consider selling antiques, rare books, period jewellery and vintage toys
• Dropshipping: this is an increasingly lucrative way to sell and is very popular with online sellers. You partner directly with suppliers to make the sales, but they hold the inventory of the items you’re selling. This means you don’t have to find storage space or worry about processing and posting once you’ve made a sale. When a sale’s completed, the product’s shipped directly from the supplier to the buyer

Making the most of your sales

You’ve made the decision of what to sell, so how best to market your products? Here are a few tips to make your sales as successful as possible.

Optimise your listings

• Make product descriptions clear: List each item’s key features or benefits in clear, concise language, and check for any spelling or grammatical errors before posting. eBay also features an AI tool to help generate listing copy to make this easier for users
• Use high-quality imagery: Try to take your photos in good lighting conditions and against a neutral background. You can add up to 24 photos per listing, perfect for showing multiple angles
• List each item’s condition accurately: Depending on the category your product comes under, you’ll have a choice of item conditions to select from. You can find more information on eBay’s help pages
• Be clear about postage: If you’re asking buyers to pay any extra postage costs, let them know in your listing. Or offer free postage and packing as an added incentive to buy. There’s lots more information on postage options in eBay’s customer service pages

Offer a great shopping experience

• Set realistic prices: This applies to both your products and postage fees. Research your competitors to see the level of pricing they use for items similar those you’re selling
• Choose how you’ll sell: Consider whether to use an auction-style or fixed-price listing. Auctions can create a sense of urgency to bid. Fixed-price listings let customers know exactly what they’ll be paying upfront
• Always give the highest levels of service: Reply to customer enquiries and questions promptly and professionally. Give as much information as you can. Be as accurate as possible. Positive reviews will help you to build a strong seller reputation and encourage repeat and new customers alike
• Set up shop: If your sales are soaring, consider setting up an eBay Shop. There’s a monthly subscription fee, but it means you can personalise your online presence. This can help your customers find you more easily and grow your business at the same time
