Tips for Building Top Ecommerce Sites

As you can see on our top ecommerce sites list, online marketplaces make up the first five items, while custom ecommerce websites make up the remaining five.

However, no matter if it is an online marketplace or a custom ecommerce website, you'll notice that top ecommerce sites have several website features in common.

Some of them you may not be able to spot immediately, but here's the good news — we've compiled them for you.

So, if you're ready to build your online store website, take note of the following website tips to design a top ecommerce site of your own:

  • Focus on a user-friendly design. There is a lot of thought that goes into designing websites. The top ecommerce sites have modern web designs that are easy to navigate, fast-loading, and responsive on both desktops and mobile devices.

Because ecommerce sites have a lot of large files (like product images), they aren't always the fastest. Page load speed is an SEO ranking factor that can affect how potential customers use your website and how it appears on search engine results.

Some website speed optimization tricks are to:

  • Choose the right web hosting provider.

  • Optimize images.

  • Enable caching.

  • Use a content delivery network (CDN).

  • Learn how to create a one-page website.

  • Build a beautiful homepage. A website’s homepage is the online version of a storefront. Create a homepage inspired by these beautiful homepage design ideas.

  • Emphasize website security. Top ecommerce sites must be secure because they deal with customers’ sensitive personal information and financial data. Ensure that your ecommerce store has an SSL certificate and is PCI-compliant.

  • Provide multiple payment gateways. Top ecommerce sites cater to customers from different countries. Although most shoppers are comfortable using PayPal or credit cards, other customers may have different preferred payment methods.

  • Offer thorough product information. Customers can't see the products in an online store firsthand. For that reason, top ecommerce sites must give users comprehensive information about the merchandise on their listings and product pages. The standard is detailed product descriptions and high-quality images.
