Benefits of User Experience in Your Company's Ecommerce

The benefits of user experience (UX) in e-commerce are measurable: customers find what they need faster, complete more purchases, return more often and cost less to serve. UX is the discipline that studies how people behave on a digital channel and designs it so that buying feels obvious, which is why it influences revenue, retention and efficiency at once.

Consider the quarterly review at a distributor of industrial supplies that launched an online store a year ago. The chief executive had approved the investment because customers kept asking for 24-hour ordering. The store works. Orders arrive on weekends, the catalog is complete and the technology team reports no incidents. Yet the commercial director has a number that nobody likes to discuss: most visitors who add a product to the cart never finish the purchase, and the sales representatives still receive the same phone calls asking where to find a part and what the real delivery date is. The platform was delivered, but the experience was never designed. The business paid for a store and received a catalog with a payment button.

That scenario is common in retail, consumer goods, financial services and B2B distribution, and it explains why the conversation about e-commerce has shifted. Having a store online is no longer a differentiator. What differentiates is how easily a person, whether a household buyer or a purchasing manager at a company, can complete a task. This article explains what UX means in the context of e-commerce, why a well-built store changes the economics of the business, which benefits a company can expect and how to keep them over time.

What is user experience (UX) in e-commerce?

User experience is a strategy that analyzes how people behave inside a website or application in order to understand their satisfaction, their perception and their emotions while using it. Its output is a set of guidelines so that the visitor has an intuitive, pleasant and memorable experience with the brand. In e-commerce the discipline has a very concrete job: to remove the reasons why a motivated person does not buy.

It helps to separate UX from appearance. A handsome store can still be difficult to use, and a plain one can convert extremely well. Good usability tends to rest on a few observable qualities. Information is presented in an order that balances novelty with the user's mental model, meaning what people are accustomed to seeing in a store. Pages load quickly. The site is responsive, the home page states what the company offers and every button and link does what it promises. And usability can be tested, with as few as five users in a moderated session or with specialized tools that score the page.

Speed deserves emphasis because it is the quality executives most often treat as a technical detail. A study commissioned by Google and carried out by 55 and Deloitte, covering 37 European and American brand sites and more than 30 million user sessions, found that a 0.1-second improvement in mobile site speed was associated with an 8.4% increase in retail conversion rates and a 10.1% increase in travel conversions, as described in the Milliseconds Make Millions case study. A tenth of a second is invisible to a manager reviewing the site on the office network, yet it is visible in the revenue line.

Why does a company need e-commerce, and in which industries does it make sense?

Digitalization has turned the website into the storefront of the company, the place where the most important aspects of the business are on display. People search for products online and expect to buy from home, from the office or from wherever they happen to be. For a physical retailer this means a digital complement becomes essential. For a company that is already digital, it means that service and features must be good enough to stand out among alternatives that are one click away.

The commercial advantages of an online store are well known, and they are worth restating in terms an executive team can weigh. The store sells every day of the week at any hour, so demand is not constrained by opening times. It extends the reach of the company by country or region without opening premises. Its operating costs are lower than those of a physical store, since it does not require a location, furniture or on-site service. It produces customer information from every person who buys or creates an account. And it allows the company to study behavior, from the products that attract attention to the ones people actually purchase, which is the raw material of better merchandising decisions.

E-commerce is recommended for large and small companies across models such as B2B, B2C and C2C. The B2B case in particular is often underestimated. A distributor whose customers reorder the same items every month benefits from a store that remembers their catalog, prices and shipping addresses, which is a different problem from the one a fashion retailer faces. ICX has examined the economics of that model in its article on the characteristics of a B2B e-commerce that reduces costs, and its service on B2B digital commerce describes how those stores are designed.

What characteristics should every e-commerce have?

An online store can take many forms, but three characteristics should always be present. The first is updated databases, both of customers and, in the case of retail, of products. A store that shows items which are out of stock, or prices that differ from those in the warehouse, destroys trust faster than any design flaw. The second is the design and development of the operating systems that sustain the store, from payments to inventory to order management. The third is that the whole is optimized for the customer experience, and it is precisely at this point that UX enters the picture.

Many companies invest heavily in the first two and treat the third as decoration to be added at the end. The consequence is a store that is technically sound and commercially mediocre. UX should be present from the beginning, when the team decides how the catalog is organized, how the customer searches, what information appears next to a product and how many steps separate the cart from the payment confirmation. For a deeper discussion of the discipline, see ICX's explanation of what user experience design is.

What benefits does UX bring to e-commerce?

The most direct benefit is conversion. Baymard Institute, which has benchmarked the checkout experience of 344 top-earning e-commerce sites in the United States and Europe, estimates that the average large-scale site could raise its conversion rate by 35% through better checkout design, and finds that 65% of those sites rate mediocre or worse on checkout usability, according to its checkout usability research. In other words, the opportunity does not lie in obscure details. It sits in the basic flow that most companies believe they have already solved.

A second benefit is knowledge of the customer. A good UX analysis provides data on who visits the store, what they like, where they come from and which tasks they attempt. By observing the tasks a user can perform and the difficulty with which they perform them, the company identifies which elements work and which are obstacles. Combined with analytics, it shows whether traffic arrives from other countries, other websites or social networks, and that information allows marketing to build strategies on evidence rather than intuition.

A third benefit is better commercial decisions about the assortment. When the company can see which elements of the store are most viewed and which ones people interact with, it can adjust inventory accordingly, increasing the depth of what attracts attention and reducing what does not. A grocery distributor or an apparel retailer that learns from the behavior of its visitors purchases more accurately and carries less dead stock, which is an effect on working capital, not just on the website.

A fourth benefit is the memory the brand leaves. The easier a page is to use, the more memorable the company becomes, and satisfied users recommend it and expand its network of customers. The purchase process also becomes faster, which benefits both parties, because the customer values his time and the company values a completed order. Finally, a store that is revised periodically stays optimized, as the habits of users and the conventions of web design continue to change.

These benefits point toward a more profound change in how a company relates to its customers. A store designed with UX does not only sell; it reduces calls to the sales team and the service center, because the answers are already on the page. A bank that places its card application behind a simple, well-explained digital process spends less on branch time and phone support. An insurer that lets a policyholder check coverage and file a claim online reduces its cost per interaction while improving the sense of control the customer feels. The efficiency and the experience improve together, and that is the combination executives are looking for.

What does a failing experience look like in practice?

Most poor experiences are not catastrophic; they are quietly expensive. Imagine a regional apparel retailer whose mobile visitors outnumber desktop visitors, yet whose size guide opens in a separate window that is difficult to close on a phone. Shoppers who are uncertain about size leave to compare with a competitor, and returns for incorrect sizes eat into the margin of those who do buy. Nothing in the dashboard signals a failure, because traffic is healthy. The loss is only visible when someone studies the behavior of the people who did not buy.

Now imagine a B2B distributor in the manufacturing sector. Its customers know exactly what part they need, but the search function expects the internal product code and returns nothing when a buyer types the manufacturer's reference. The buyer calls the sales representative, who looks up the part in the system and places the order by phone. The store exists, the representative's time is consumed and the cost to serve is no lower than before. Observing five real buyers attempt to find five real parts would reveal the problem in an afternoon.

The common thread is that the cause lies in the distance between how the company organizes information and how the customer thinks about it. UX research closes that distance. It starts with observation, continues with design decisions based on what was observed and ends with testing to confirm that the decision improved the outcome. That sequence is what separates a store that is merely online from one that is commercially effective.

How do you maintain UX over time?

User experience is an iterative process, not a project with a closing date. People's expectations, motivations and the problems they are trying to solve change, and so do trends in web design and the behavior of the devices people use. A UX analysis conducted once, at launch, begins to age the day after. The sensible approach is to establish a regular cadence, for example a quarterly review of the main journeys, supplemented by a deeper study whenever the company introduces a new product line, payment method or market.

Maintaining UX also means reviewing the functionality of every element of the store. A promotional banner that links to an expired offer, a filter that no longer works after a catalog update or a form that rejects valid phone numbers from a new country are small failures that accumulate. ICX's article on inbound marketing and UX design for a great customer experience shows how content and design should be reviewed together, and the piece on how to improve UX through omnichannel explains why the store must be consistent with the other channels the customer uses.

What does this mean for the C-level?

For a chief executive, the lesson is that UX is a commercial investment with a return, not a design expense. The question to ask the e-commerce team is not whether the site is attractive, but how long it takes a first-time customer to complete the three most important tasks and what share of them succeed. Those two numbers connect the quality of the interface to revenue, and they can be tracked every month.

For the finance and operations leaders, the relevant effect is on cost to serve. Every task that customers can complete without help reduces calls, emails and manual order entries, and the savings compound as volume grows. For marketing and sales, the benefit is conversion and loyalty: traffic that was expensive to acquire has a better chance of becoming a customer, and customers who find the experience easy are more likely to return and to recommend the brand. The best-run companies treat these effects as a single agenda and assign one executive to the end-to-end journey rather than leaving it divided among design, technology and sales.

Proof that this approach works is available from many organizations. ICX has collected examples in its article on the best success stories of companies with UX/UI strategies, which illustrate how companies of different sizes translated research into measurable results.

How to start on Monday morning

A seasoned consultant would not begin with a redesign. He would begin by watching. Ask five customers, ideally a mix of new and loyal ones, to complete three typical tasks on your store while you observe without helping: find a specific product, add it to the cart and pay. Note where they hesitate, what they misread and which questions they ask aloud. Five sessions are usually enough to reveal the most serious obstacles, and they cost an afternoon rather than a budget line.

Then compare what you saw with your numbers. Look at where in the funnel visitors leave, which searches return no results, how long the main pages take to load on a mobile phone and which questions reach your service team about information that should already be on the site. Choose the two or three obstacles that appear in both the observation and the data, fix them and measure again after a few weeks. Repeat the cycle every quarter. Companies that make this a habit rarely need a dramatic overhaul, because they correct small problems before they become expensive ones.

Frequently asked questions

What is the difference between UX and UI in an online store?

UI refers to the visual elements of the interface, such as colors, typography and buttons. UX covers the whole experience, including how easy it is to find a product, how clear the information is, how fast pages load and how smooth the payment is. A store can have an attractive UI and a poor UX, which is why companies should evaluate both together.

How many users are needed to test the usability of an e-commerce site?

For a first diagnosis, sessions with about five representative users are usually enough to uncover the most serious usability problems. Automated tools can complement this by scoring the page and tracking behavior at scale. The test should be repeated after each major change, and whenever analytics show a sudden drop in conversion.

How often should an e-commerce UX analysis be repeated?

UX is not a one-time task. A quarterly review of the main journeys is a reasonable cadence for most companies, with additional studies when they launch new products, payment methods or markets. User expectations and design conventions keep changing, so a store that was optimized two years ago may now be creating friction.

Does UX matter for B2B e-commerce as much as for B2C?

Yes, and sometimes more. Business buyers reorder frequently, work with specific references and expect prices, credit terms and delivery details tied to their account. A store that reflects those needs reduces calls to sales teams and speeds up repeat orders, which directly lowers the cost to serve.

A store that is easy to use makes a business easier to choose, and in a market where the next competitor is one click away that quality carries real commercial weight.
