The first thing to keep in mind when you want to enhance your eCommerce user interface is to present simple navigation that guarantees uninterrupted consideration of customer purchase. Online users should be able to browse through different product pages and reach the checkout screen without any hindrance. 

In order to do so, site navigation options should be improvised to best ensure smooth movement from one step to the next:

  • The main menu should be clean and appealing that contains essential categories.
  • Sub-categories should be included in the drop-down list and automatically displayed when the cursor hovers over the category.

The home page of any website is probably the most crucial and creative area in UI design as this is the first thing that grabs users’ attention when they land on your eCommerce stores. Therefore, homepage design should focus on immediately highlighting your brand and services in a few seconds.

3. Product page

Every product page should aim at giving customers a full understanding of the product they are looking at. To improve Product Page UI Design, eCommerce stores can:

  • Enable the zoom in/ zoom out functionality of the product images.
  • Display product images in carousel mode. 
  • Include product videos, size chart and product reviews section.

It’s worth noticing that all pertinent details, including discount codes, payment options, extra fees or return policies shall be shown at once on product pages. However, these pieces of information should be made small on non-intrusive widgets to free up the product pages to primarily focus on product details.

4. Checkout screen

Normally, there are two checkout screen options, which are fitting everything into one page and breaking the checkout process into several pages. 

A major benefit of one-page checkout is its accessibility and convenience, as everything customers need to make the final purchasing steps is there. However, it also leads to an overwhelming of information packed in only one page, which might make customers find it sophisticated to complete all needed elements at once.

Therefore, eCommerce businesses might benefit more from a multi-page checkouts design option. Break down the checkout process into two to three screens can minimize the probability of the customer making a mistake or skipping some information.

There are several feature-wise elements that should be included in the Checkout Screen to motivate customers to finish their orders:

  • Multiple payment options
  • Money-back guarantee policy
  • “Add to wishlist” button

5. Mobile responsive design

In 2021, mobile traffic was responsible for 53.9% of all total global e-commerce traffic, meaning that more than half of store online traffic came from smart devices. Therefore, mobile responsive design has become the top priority of any online retail business for the last few years. 

For a practical mobile responsive design, UI designers need to conduct detailed research on which devices, screen sizes, and web browsers are most prevalent today before making a final design plan. Keep in mind that responsive design isn’t simply about making your web page fit any user device, it’s about optimizing the design to match capabilities of the device hardware as well as the device resolution.
