Australians spent $82.6 billion online in 2025, around 24 percent of all retail spending, according to Australia Post’s eCommerce Report. A growing share of that money goes to stores that make buying feel simple. Good ecommerce website design is what creates that feeling, and it has far more to do with clear product information and a smooth checkout than with how striking the homepage looks.
At a glance
An online store has to help people find a product, decide it is right for them and pay without friction. This article covers how ecommerce design differs from a service website, product pages, navigation, checkout, speed and measurement. It is written for owners planning a new store or improving one that is not converting as well as it should.
The principles below apply whether you sell a handful of products or several thousand.
How an online store differs from a service website
A service website usually aims to start a conversation, so its job ends when someone calls or fills in a form. An online store has to complete the whole sale on its own. The visitor needs to understand the product, trust the business, choose options, add to cart and pay, often without speaking to anyone. Every one of those steps is a point where a sale can be won or lost.
Many of the foundations are still shared. Clear structure, genuine proof and a fast, accessible experience matter just as much, and our small business website design guide explains them in detail. The difference is mainly in where the effort goes. In a store, most of it belongs on product pages and the checkout, and the marketing behaves differently too, as our comparison of lead generation and ecommerce campaigns shows.
Product pages that answer the buying questions
Because there is no salesperson, the product page has to answer the questions a shopper would otherwise ask. What exactly is it, will it suit me, what does it cost to have it delivered, and what happens if it is not right? Pages that answer these clearly tend to sell better than pages that rely on a single photo and a line of copy.
Good photography does much of this work, showing the item from several angles and in use. Descriptions should then cover the details people need to decide, such as sizes, materials, compatibility or care, written in plain language rather than manufacturer jargon. Reviews from real customers add the reassurance that only other buyers can give.
Help Google understand your products
Product pages can also carry structured data that describes the price, availability and reviews in a form search engines can read. Google’s documentation on product structured data explains how this can make your listings eligible for richer results in search. Most modern ecommerce platforms add the basics automatically, but it is worth checking that the information is complete and accurate.
Navigation and search that help people find products
Before a product page can sell, the shopper has to find it. Categories should follow the way customers think about your range, using the words they would use, rather than your internal product codes or supplier groupings. For a small range, a simple menu may be enough. As the range grows, filters for size, price, colour or other relevant attributes become essential.
On-site search deserves particular care, because people who search usually know what they want. A search that handles misspellings and common synonyms, and shows useful results instead of an empty page, keeps those ready buyers on the site.
Checkout: where ecommerce website design wins or loses sales
Even a well designed store loses many shoppers between the cart and the confirmation page. Baymard Institute’s average of 50 studies puts the documented cart abandonment rate at about 70 percent. Some of that is simply people browsing or comparing prices, and Baymard notes it is largely unavoidable. The rest is where design can help.
Baymard’s research with US shoppers found that, setting aside those who were just browsing, the most common reason for abandoning a cart was extra costs such as shipping being too high, cited by 40 percent. Eighteen percent left because the site wanted them to create an account, and 17 percent because the checkout was too long or complicated. The practical lessons follow directly. Show delivery costs early, offer guest checkout, ask only for the information you need, and give people the payment options they expect.
Speed and the mobile experience
Many shoppers browse and buy on their phones, so the store has to work smoothly on a small screen. Large product images are the usual cause of slow pages, and they can be compressed and sized properly without losing quality. Google’s Core Web Vitals give useful targets, including loading the main content within 2.5 seconds.
Apps and plugins are the other common drag on speed, so it pays to review them regularly and remove any that are not earning their place.
Measuring and improving what the store produces
Ecommerce has a real advantage here, because every sale can be tracked back to the visit that produced it. That only works if purchases and their values are recorded accurately, which is why conversion tracking should be set up and tested before launch.
With reliable data in place, you can see where shoppers drop out and test changes to fix it. That steady process of conversion rate optimisation often adds more revenue than a full redesign, because it builds on what customers are already doing. It also helps to grow your own customer list alongside any marketplace sales, a point we explore in why your own customer list matters.
Common ecommerce design mistakes
The most common mistake is designing the store around the homepage. Shoppers often land directly on a product or category page from search or an ad, so those pages need the most attention. A second is hiding costs until the final step, which surprises shoppers at the moment they are about to commit. A third is launching without tested tracking, which leaves you guessing about what is working.
Building an online store that sells
Successful ecommerce website design comes down to removing doubt and friction at each step. Clear product information, simple navigation, a short and honest checkout and fast mobile pages do more for sales than any visual trend. When comparing ecommerce website design services, ask how a provider approaches these elements and how they will measure results, whether you are briefing a team for an ecommerce website in Perth or elsewhere in Australia. You can read how we approach this on our website design page.
