Top 15 Online Selling Sites In 2025

1. Amazon

Amazon is hands down the largest online marketplace, with millions of people visiting daily.

As one of the biggest online selling sites, it offers huge opportunities for sellers to reach a massive audience. With its endless product categories, it draws in customers of all kinds, making it one of the go-to platforms for online shopping.

Think about it—over 315 million active accounts scroll through countless listings every month. That kind of traffic can drive serious visibility to your store and products.

For sellers, Amazon keeps it flexible. If you’re just starting or only have a few items, you can go for the Individual plan which is $0.99 per item sold.

For those with bigger inventories or more ambitious goals, the Professional plan ($39.99/month) is a better fit. It’s all about choosing what works for your business.

Amazon also comes packed with tools to help you out. You can manage inventory, track sales, and improve your listings to boost your chances of success. These tools are game-changers for anyone serious about selling online.

Now, let’s talk costs. While Amazon gives you amazing exposure, there are fees to keep in mind.

You’ll encounter referral fees (which can range from 6% to 45%, depending on the product category), closing fees, and a monthly subscription fee for professional accounts.

These add up, so you’ll want to crunch the numbers to keep your profits in check.

Next up, I’ll dive into eBay, where sellers get to mix things up with bidding wars and direct sales. Stay tuned!

2. eBay

eBay is one of the top online selling sites, offering a mix of auction-style and direct sale listings. It’s known for its diversity—you can list almost anything, from everyday items to rare collectibles. Whether you’re a casual seller or running a small business, eBay caters to all levels of sellers.

One of eBay’s unique strengths is its auction feature, which allows buyers to bid on items. For highly sought-after products, this can drive up prices and maximize your profits. It’s a great way to sell items like limited-edition collectibles, vintage goods, or rare finds that spark competition among buyers.

For beginners, eBay keeps it simple. You get free listings for a limited number of items, letting you test the waters without upfront costs. This feature is perfect if you’re clearing out second-hand goods or trying out new product ideas.

Just remember, eBay initially imposes selling limits, which gradually increase as you establish a good track record.

Additionally, keep in mind that eBay’s fees, such as service fees and transaction fees, do not include sales tax, which is a separate consideration when pricing your items and calculating overall costs.

What sells best on eBay?

Think unique and hard-to-find products. Items like collectibles, vintage goods, electronics, and branded fashion often perform exceptionally well.

eBay also has a strong market for refurbished or second-hand items, appealing to bargain hunters and eco-conscious buyers alike.

When it comes to fees, eBay charges insertion fees (for listings beyond the free limit) and final value fees based on the sale price. The insertion fee varies based on the number of listings and additional factors like category selection.

These fees typically range from 10% to 15%, depending on the category. Certain items, like electronics, might incur slightly higher fees, so it’s important to account for this in your pricing to maintain profitability.

In short, eBay is a top-tier platform for online sellers, especially if you offer unique products or want to experiment with auction-style listings.

With over 133 million active buyers, the potential to grow your sales is immense. Just keep an eye on selling fees and tailor your strategy to the platform’s strengths.

3. Etsy

Etsy is a go-to platform for anyone selling handmade items, vintage goods, or craft supplies.

It’s all about unique and creative products, making it a favorite among buyers looking for something special instead of mass-produced goods. If your products stand out, Etsy is the perfect place to showcase them.

One of the best things about Etsy is its strong community support. As a seller, you’ll find forums, resources, and networking opportunities that help you learn the ropes, spot trends, and improve your listings.

Whether you’re new to selling or a seasoned pro, this supportive environment can make a big difference in your success.

What sells best on Etsy?

Handmade jewelry, personalized gifts, vintage home décor, and craft supplies consistently perform well.

Etsy facilitates online sales by providing a user-friendly platform for sellers to reach a broad audience. Seasonal and niche items—like wedding accessories or holiday decorations—also thrive, as buyers often turn to Etsy for one-of-a-kind finds.

Another standout feature is Etsy’s low fees, which help sellers keep more of their earnings.

The platform charges a $0.20 listing fee per item and a 5% transaction fee on each sale—significantly lower than giants like Amazon or eBay. These lower fees encourage creativity and innovation among sellers while making the platform cost-effective.

If you’re looking to sell unique, handmade, or vintage items, Etsy is the perfect choice. Its creative-focused audience and seller-friendly environment make it a favorite for small business owners and hobbyists alike.

4. Shopify

Shopify remains a top choice for building an online store, and it’s perfect for entrepreneurs looking to make a strong impression in 2025.

The platform is known for its user-friendly interface, making it easy for anyone to create an online store without needing technical skills. This allows online selling sites to get up and running quickly, connecting with customers in today’s fast-paced eCommerce world.

One of Shopify’s biggest strengths is its SEO and marketing tools. You can customize title tags and meta descriptions to help your store rank higher on search engines, driving more traffic to your products. This kind of visibility is essential for standing out among other selling platforms.

Shopify also excels in integrating with other sales channels. Sellers can connect their stores to social media platforms and online marketplaces, opening up even more opportunities for sales.

Thus, this multi-channel approach lets you meet your customers wherever they are, boosting your reach and potential revenue.

Another perk? Over 1 million businesses trust Shopify to manage inventory, orders, and operations all in one place. This means you can focus on growing your business while Shopify handles the backend.

However, if you want to start using this platform, the pricing options start from $32/month.

If you’re serious about growing your online presence, Shopify is a game-changer. Its powerful tools and integrations make it one of the best platforms for launching and scaling your business in 2025.

5. Poshmark

Poshmark stands out as one of the top online selling sites for clothing and lifestyle accessories, thanks to its community-driven approach.

It’s more than just a marketplace—it’s a social hub where users can like, share, and comment on listings, building trust and boosting sales. This interactive element makes it especially popular among fashion enthusiasts and sellers.

What can you sell on Poshmark?

While the platform is best known for clothing, you can also list accessories, shoes, handbags, and even home goods. Brand-name and gently used items often perform best, but vintage or unique pieces can also attract buyers.

Selling on Poshmark is incredibly easy. The listing process is straightforward— simply snap pictures of your items, write up the details, and set a price.

It’s beginner-friendly but also caters to experienced sellers, making it a versatile choice for anyone diving into the resale market.

One of Poshmark’s most convenient features is its prepaid shipping solution. After a sale, you receive a prepaid shipping label, so all you need to do is pack up the item and drop it off.

No need to worry about calculating shipping costs or finding the right box—Poshmark makes the process seamless. Understanding the shipping fees is crucial as they can significantly impact your total expenses and final sale prices.

When it comes to fees, Poshmark charges a flat $2.95 for sales under $15 and takes a 20% cut for sales over $15. While this is higher than some platforms, the ease of use and built-in audience can make it worthwhile for sellers, especially those focused on fashion and accessories.

If you’re considering selling online in 2025, Poshmark’s focus on community, simple listing process, and streamlined shipping make it a top choice for anyone looking to succeed in the fashion resale market.
