eCommerce usability: the ultimate guide

Usability is an integral part of holistic SEO. It influences factors such as bounce rate, time on page and conversion rate, to name a few, and many of these metrics affect your website’s SEO. Optimizing usability is essential for all sites, but even more so for eCommerce sites.

User testing is one way to optimize your eCommerce shop, but a lot can be done just by looking at best practice, comparing that with your site and making improvements. This ultimate guide to eCommerce websites takes you through that testing process and looks at everything you need to address to give your visitors the best experience possible.

In short, this usability guide for online shops will tell you all about:

That’ll cover most if not all of your visitors’ on-site shopping experience. Let’s get started!

Online store homepage usability 101

Have you ever looked closely at the homepage of your online shop? Chances are you just went with the WooCommerce theme that your designer presented and implemented the available options. While most of these themes are nicely designed and set up with the user in mind, that might not be best for your particular target audience.

Focus on your target audience

Before setting up a design, you need to understand the needs of your target audience. Are these people looking for the best price, or do they want to read a dozen reviews before buying? Are there cultural differences you need to take into account? These things determine the setup and layout of your shop’s homepage. Do you need to highlight sale items? Are you addressing a particular niche? If so, you’ll need to make that clear from the start.

If one of the pillars of your mission is to provide the best price possible, the sale banner should probably be the most prominent item on your homepage. But, if you are selling high-quality products that people are willing to pay a bit more for, sentiment and emotion should be your focus. You could use larger images and focus on core product features and benefits.

Homepage call-to-action

The job of your homepage is to guide the visitor to your products. The homepage of your online store shouldn’t necessarily be set up with SEO in mind but should focus on the user instead. That also means you’ll have to create a killer call-to-action on that homepage. Here are some useful tips for setting up that call-to-action:

After welcoming the visitor to your website, you can guide them to where you make your money: the product pages. Before we address these, let’s look at how to optimize internal search, and category/landing pages.

Internal search is the most important navigational option for your online shop, and you should optimize it to the max. You’ll have noticed that the larger brands and online shops all focus a lot on their internal search. The reason is simple: if you can find the product you are looking for, you can buy it!

As well as optimizing that internal search option, you need to make sure that your search result pages look focused and give a great overview. You need to show the price and even an ‘Add to Cart’ button next to the product’s name and image, and a comparison option will come in handy if, for example, you have a shop selling Bluetooth speakers.

Filter options

After the search query, online clothing shops will allow for filtering by size, gender, color – the lot. Filtering options like these, or sorting by price or availability, will help your visitor to find the product they want as quickly as possible. To read more about this and see some examples, I recommend my post Enhance online shopping with eCommerce filters.

Category page optimization

Your category pages could be even more important than your product pages because they give the visitor the option to choose and compare, much like your internal search result pages. Your shop category page should be considered a regular page for SEO, but is so much more important when it comes to usability.

Here are some of the things you need to keep in mind:

You should also optimize your landing pages.

Landing page optimization

A landing page is a page where your visitors end up when they follow a link from outside the site, for example search engines or social media. Landing pages on your online shop should be optimized to evoke a particular reaction from the visitor, such as buying a specific product.

Focus on one product or product bundle and optimize that page to guide your visitor to the purchase – in other words, welcome them. Make sure the visitor feels safe paying you by setting up SSL on your site and maybe adding trust signals. Add social proof in the form of testimonials, so your visitor will understand why your product is so good, and why they need it.

We strongly recommend using headings and images to deliver your message as these help a lot, particularly for buyers scanning your landing page. Make sure these deliver the right message to your visitors.

And so, on to product pages.

Product page optimization

 Generally speaking, make your product page as usable as possible. Product pages need to be optimized for SEO, by using schema.org data and perhaps OpenGraph text. Read more about that in our article on product page SEO. But when your visitor arrives on that page, you need to convince them to buy.

Best practices

Let’s go over some best practices for product pages:


Just like your homepage, your product page needs a strong call-to-action. In most cases that will be the Add to Cart button. Limit all distractions, make the text actionable, and use the right color. And if possible, add a review somewhere near that button. There’s more on calls-to-action here, and more on button design here.

After your product page, customers proceed to your shopping cart, which is part of your checkout process.

Checkout page optimization

You are about to close the deal: the customer wants to buy your product, so let’s gently guide them to our payment page. The first thing we need is to tell them where we are in the checkout process, so be sure to add a progress bar.

At the start of the checkout process, we give the customer an overview of the products they want to buy. This is, of course, the same as the cart overview. There are a couple of elements that are required here:

Guest purchase

You should also make sure a guest purchase is possible. Having to register for a one-time sale is a deal-breaker for me.

Short forms

If you need to ask for more than just an email address, make sure to make the form as short as possible. Think about useful things like a checkbox to confirm that the delivery and invoice address are the same, instead of making customers fill in their details twice.


Make payment easy by choosing a trusted payment provider and offering convenient payment options. These will vary depending on the shop and its customer base.

Finally, after that optimized shopping process, a happy customer will leave your online shop. Now make sure you keep that customer happy. There are some extra things you can do to make that happen and you’ll find more tips in our article on checkout page UX!

Conclusion: eCommerce usability is a trade of its own

Don’t trust your theme or eCommerce platform to fill in the blanks for you. Put some real effort into optimizing the usability of your eCommerce website. You’ll find that a better user experience will bring the SEO and conversion of your online store to the next level.
