Your eCommerce store’s design is not just about looking good. It is a conversion engine that either helps or hinders every visitor’s journey from browsing to buying. Small design changes can have an outsized impact on revenue, and the most successful online stores treat design as a strategic tool for driving sales, not just a visual exercise.
In this guide, we share four proven design tips to increase eCommerce sales. These are practical, tested strategies that Australian online retailers can implement to improve product page performance, streamline checkout, build trust, and ultimately turn more visitors into paying customers.
Why eCommerce Design Directly Impacts Revenue
The relationship between design and eCommerce revenue is well documented. Research by the Baymard Institute shows that the average cart abandonment rate across all industries is nearly 70%. That means seven out of ten shoppers who add a product to their cart leave without completing the purchase. While some abandonment is inevitable (comparison shopping, for instance), a significant portion is caused by poor design, confusing checkout flows, and a lack of trust signals.
Even modest improvements in conversion rate deliver substantial revenue gains. If your store does $500,000 in annual revenue with a 2% conversion rate, increasing that to 2.5% would generate an additional $125,000 in sales without spending a single extra dollar on advertising. Design is one of the most cost-effective levers you have for growing eCommerce revenue.
Tip 1: Optimise Your Product Pages for Decision-Making
Product pages are where buying decisions are made or abandoned. Every element on these pages should help the customer answer two questions: “Is this the right product for me?” and “Can I trust this store enough to buy?” Here is how to design product pages that answer both questions convincingly.
Product Images That Sell
Images are the most influential element on any product page. Online shoppers cannot touch, hold, or try your products, so your photography needs to bridge that gap.
- Use multiple high-quality images. Show the product from every relevant angle. Include close-ups of materials, textures, and details. Five to eight images per product is a good target for most categories.
- Include lifestyle images. Show the product in use or in context. A piece of furniture photographed in a styled room communicates scale, colour accuracy, and lifestyle appeal far better than a white-background studio shot alone.
- Enable zoom functionality. Let users zoom in to examine details closely. This replicates the in-store experience of picking up a product and inspecting it.
- Add video where possible. Product videos can increase purchase likelihood by up to 85%. A 30-second video showing the product from all angles, demonstrating functionality, or showing it in use is tremendously effective.
- Maintain consistency. Use consistent backgrounds, lighting, and styling across all product photos. Inconsistent imagery makes your store look unprofessional and erodes trust.
- Optimise for speed. High-quality does not mean high file size. Compress images using modern formats like WebP or AVIF, and implement responsive images so mobile users are not downloading desktop-sized files.
Product Descriptions That Convert
Your product descriptions should do more than list specifications. They need to help the customer envision owning and using the product.
- Lead with benefits, then provide features. Tell customers what the product will do for them before listing technical specifications. “Stay cool and comfortable on the hottest summer days” is more compelling than “100% breathable cotton, 180 GSM.”
- Address objections proactively. Think about why someone might hesitate to buy, then address those concerns in the description. If sizing is a common concern, include detailed sizing guidance. If durability matters, talk about materials and construction quality.
- Use scannable formatting. Use bullet points for key features, short paragraphs for benefit statements, and clearly labelled sections for specifications, materials, and care instructions.
- Include social proof in context. Weave in mentions of customer satisfaction where relevant: “Our most popular seller” or “Rated 4.8 stars by over 500 customers.”

Visual Hierarchy and Layout
The layout of your product page should guide the eye naturally from the product image to key information to the add-to-cart button.
- Place the add-to-cart button above the fold. The primary call to action should be visible without scrolling on both desktop and mobile.
- Show price prominently. Do not make customers hunt for the price. Display it clearly near the product title and add-to-cart button.
- Highlight sale prices effectively. Show the original price crossed out next to the sale price, and indicate the percentage saved. Use colour (typically red) to draw attention to the discount.
- Display stock availability. Showing “Only 3 left in stock” creates urgency without being dishonest. If an item is out of stock, offer a notification option so customers can be alerted when it returns.
- Use sticky add-to-cart on mobile. As mobile users scroll through product details, keep the add-to-cart button visible with a sticky bar at the bottom of the screen.
Tip 2: Streamline the Checkout Process
Checkout is where the highest-value abandonment happens. A customer who has found a product, decided to buy it, and added it to their cart is highly motivated. If they abandon at checkout, the design of your checkout process is likely at fault.
Reduce Checkout Steps
Every additional step in your checkout flow is an opportunity for the customer to reconsider or get frustrated. Aim to minimise the number of pages and fields between “Add to Cart” and “Order Confirmed.”
- Offer guest checkout. Forcing account creation before purchase is one of the top reasons for checkout abandonment. Let customers buy first and offer account creation on the confirmation page. You already have their email and shipping details; creating an account can be as simple as setting a password.
- Use single-page checkout where possible. Consolidating shipping, payment, and order review onto a single page reduces friction. If you must use multi-step checkout, show a progress indicator so customers know how many steps remain.
- Only ask for essential information. Every field you add increases abandonment. Do you really need a phone number? A company name? Eliminate everything that is not strictly necessary to process the order.
- Auto-detect where possible. Use postcode lookup to auto-fill city and state fields. Use the shipping address as the billing address by default with an option to change it. Pre-select the most popular shipping option.
Payment and Shipping Transparency
Unexpected costs at checkout are the number one reason for cart abandonment globally. Address this head-on:
- Show shipping costs early. Display estimated shipping costs on the product page or in the cart, not as a surprise at the final checkout step. Better yet, offer free shipping with a minimum order value and promote this prominently.
- Offer multiple payment options. Accept credit cards, PayPal, Apple Pay, Google Pay, and buy-now-pay-later services like Afterpay or Zip. Australian consumers increasingly expect BNPL options, particularly for purchases over $100.
- Display order totals clearly. Show an itemised breakdown of product costs, shipping, taxes, and any discounts at every stage of checkout. No surprises means no abandonment from sticker shock.

Mobile Checkout Optimisation
With the majority of eCommerce traffic coming from mobile devices, your checkout must work flawlessly on small screens:
- Use large, tap-friendly input fields and buttons
- Trigger the correct mobile keyboard for each input type (numeric for phone and card numbers, email for email fields)
- Implement mobile payment methods (Apple Pay, Google Pay) that bypass manual form entry entirely
- Keep the checkout layout single-column on mobile for easy top-to-bottom flow
- Make error messages specific and display them next to the relevant field

Tip 3: Build Trust Through Design
Trust is the invisible currency of eCommerce. Shoppers need to believe that your products are as described, that their payment information is secure, and that you will deliver on your promises. Design plays a critical role in establishing this trust.
Social Proof Elements
Social proof is the most powerful trust builder in eCommerce. When potential customers see that others have bought and been satisfied, their purchase confidence increases dramatically.
- Customer reviews and ratings: Display star ratings prominently on product pages and in product listings. Show the total number of reviews alongside the average rating. Allow customers to filter reviews by rating, relevance, and recency. Include reviews with photos for maximum credibility.
- User-generated content: Feature customer photos and videos of your products in use. A gallery of real customers wearing your clothing or using your products is more persuasive than any marketing copy.
- Purchase notifications: Subtle notifications showing recent purchases (“Sarah from Melbourne purchased this item 2 hours ago”) create a sense of activity and social validation. Use these sparingly and honestly.
- Testimonials and case studies: For higher-value products, detailed testimonials or case studies that describe the customer’s experience and results are powerful conversion tools.
Security and Payment Trust Signals
- SSL certificate: This is non-negotiable. Your entire site should run on HTTPS, and the padlock icon should be visible in the browser bar. Customers who see “Not Secure” warnings will not complete purchases.
- Payment security badges: Display recognisable security badges from your payment providers (Visa, Mastercard, PayPal, Afterpay). Place them near the payment form and in the footer.
- Clear privacy policy: Link to your privacy policy near form fields and checkout, reassuring customers that their data is protected.
- Money-back guarantee: If you offer a satisfaction guarantee or return policy, display it prominently on product pages and during checkout. “30-Day Money-Back Guarantee” removes a major barrier to purchase.
Professional Design Quality

The overall quality of your design communicates professionalism and legitimacy:
- Consistent branding across all pages (colours, fonts, tone of voice)
- Professional, high-quality imagery throughout
- No broken links, missing images, or formatting errors
- Clear contact information including a physical address and phone number
- Professional “About Us” page with real team photos and your business story
- Active and linked social media profiles

Tip 4: Master Visual Hierarchy and CTA Placement
Visual hierarchy is the arrangement of design elements to guide the user’s eye toward the most important actions. In eCommerce, the most important action is almost always “Add to Cart” or “Buy Now.” Every design decision should support this primary conversion goal.
Designing Effective Calls to Action
Your CTA buttons are the most critical interactive elements on your eCommerce site. Here is how to design them for maximum impact:
- Use contrasting colours. Your primary CTA should be the most visually prominent element in its area. Use a colour that contrasts strongly with its surroundings. If your site uses a blue colour scheme, an orange or green CTA will stand out. The specific colour matters less than the contrast.
- Make CTAs large enough. Particularly on mobile, CTA buttons should be large, prominent, and easy to tap. A minimum height of 44 pixels is recommended, but larger is better for primary actions.
- Use action-oriented text. “Add to Cart” is clear and direct. “Buy Now” creates urgency. “Get Yours Today” adds personality. Avoid vague labels like “Submit” or “Continue.”
- Create visual breathing room. Surround your CTA with whitespace so it stands out from surrounding elements. A button crammed between other content elements loses its visual impact.
- Maintain one primary CTA per view. If you present multiple equally weighted actions, you create decision paralysis. Have one primary CTA (add to cart) and make secondary actions (add to wishlist, compare) visually subordinate.
Homepage and Category Page Hierarchy
Beyond product pages, your homepage and category pages need strong visual hierarchy to guide shoppers toward products:
- Hero section: Lead with your strongest offer, bestselling collection, or current promotion. Use a compelling image and a clear CTA that takes users directly to the relevant products.
- Category navigation: Make product categories visually prominent and easy to browse. Image-based category cards are more engaging than text-only lists.
- Featured products: Showcase bestsellers, new arrivals, or hand-picked recommendations on the homepage. These curated selections reduce choice overload and guide shoppers toward popular items.
- Sale and promotional banners: Use visual prominence (size, colour, position) to highlight time-sensitive offers without overwhelming the page. One strong promotion is more effective than five competing ones.
Mobile-Specific Hierarchy
On mobile devices, visual hierarchy becomes even more critical because screen space is limited:
- Prioritise product images and key information (name, price, rating) above the fold
- Use sticky add-to-cart bars that remain visible as users scroll through product details
- Implement bottom-sheet patterns for variant selection (size, colour) instead of dropdown menus, which are harder to use on touch screens
- Show the most important trust signals (returns policy, star rating) near the CTA, not buried further down the page
Bonus: Quick Wins for Immediate Impact
Beyond the four main tips, here are additional design improvements you can implement quickly for measurable results:
- Add a search bar with autocomplete. Make it prominent and include product suggestions, images, and prices in the autocomplete dropdown. On-site search users convert at two to three times the rate of non-searchers.
- Implement product recommendations. “Customers also bought,” “You might also like,” and “Complete the look” sections increase average order value and help customers discover relevant products.
- Simplify returns messaging. A clearly communicated, hassle-free returns policy reduces purchase anxiety. Display it on product pages, in the cart, and during checkout.
- Add urgency tactfully. Countdown timers for genuine sales, low-stock indicators, and free shipping thresholds can motivate faster purchase decisions without resorting to dark patterns.
- Optimise your site speed. A one-second delay in load time can reduce conversions by 7%. Compress images, minimise scripts, and use a CDN with Australian edge servers.

Measuring the Impact of Design Changes
Design improvements should be data-driven, not based on hunches. Use these approaches to measure the impact of your changes:
- A/B testing: Test one design change at a time (button colour, product page layout, checkout flow) and measure the impact on conversion rate. Tools like Google Optimize, VWO, or Optimizely make this straightforward.
- Heatmaps and session recordings: Use tools like Hotjar or Microsoft Clarity to see where users click, how far they scroll, and where they encounter friction.
- Funnel analysis: Track the drop-off rates at each step of your purchase funnel in Google Analytics 4. Identify the steps where you lose the most customers and focus your design improvements there.
- Revenue per visitor: This metric combines conversion rate and average order value into a single number, giving you a holistic view of how design changes affect overall revenue performance.

Putting It All Together
Effective eCommerce design is not about following every trend or adding every feature. It is about understanding your customers’ needs and removing every barrier between their interest and their purchase. By optimising your product pages, streamlining checkout, building trust through design, and mastering visual hierarchy, you create a shopping experience that feels effortless and trustworthy.
Start with the area that has the most room for improvement in your store. If your product pages have low add-to-cart rates, focus there first. If your checkout abandonment rate is high, tackle that. Measure the impact of each change, learn from the data, and keep iterating. The best eCommerce stores are never finished; they are constantly evolving based on customer behaviour and data.

What is the most important design element on an eCommerce product page?
Product images are the most influential design element on eCommerce product pages. Since online shoppers cannot physically interact with products, high-quality photos from multiple angles, lifestyle shots, zoom capability, and product videos are essential for helping customers make confident purchase decisions. After images, a clear add-to-cart button, visible pricing, and customer reviews are the next most important elements.
How can I reduce cart abandonment on my eCommerce store?
Reduce cart abandonment by offering guest checkout, showing shipping costs early (or offering free shipping), minimising the number of form fields, displaying security badges and trust signals, offering multiple payment options including buy-now-pay-later, and optimising the mobile checkout experience. The most common reason for abandonment is unexpected costs at checkout, so transparency about total costs from the start is critical.
What colour should my add-to-cart button be?
The specific colour of your add-to-cart button matters less than the contrast it creates with its surroundings. The button should be the most visually prominent element in its area of the page. Choose a colour that contrasts strongly with your site’s colour scheme. Green, orange, and red are common choices, but what matters most is that the button stands out and is easy to find.
Do customer reviews really increase eCommerce sales?
Yes. Research consistently shows that customer reviews significantly increase conversion rates. Products with reviews see conversion rate increases of 10-30% compared to products without them. Reviews provide social proof that reduces purchase anxiety, and even negative reviews can increase trust by showing that the reviews are genuine. Display star ratings, total review counts, and allow filtering by rating for maximum impact.
How does page speed affect eCommerce conversions?
Page speed has a direct impact on eCommerce conversions. Research shows that a one-second delay in page load time can reduce conversions by approximately 7%. Google recommends that the main content should load within 2.5 seconds. For eCommerce sites, optimise images, minimise scripts, use modern image formats like WebP, implement lazy loading, and use a CDN with servers in Australia for the best performance.
Should I offer guest checkout on my eCommerce store?
Yes, offering guest checkout is strongly recommended. Forcing account creation before purchase is one of the top reasons for checkout abandonment, with studies showing it causes approximately 24% of abandonments. Let customers buy without creating an account, then offer account creation on the order confirmation page. You already have their details from the purchase, so creating an account can be as simple as setting a password.
