How to Design an Ecommerce Website: Best Practices

Two online stores can sell the same products at the same prices and still have very different results. One makes it easy to find the right item, understand it, trust the seller and pay in a minute. The other hides the search bar, shows blurry photos, surprises buyers with shipping costs at the last step and asks them to create an account before paying. The difference is design.

This guide explains how to design an ecommerce website that converts, whether you run a small brand or a large catalog. It covers homepage and navigation, search and filters, product pages, cart and checkout, mobile UX, trust signals, design systems, testing and real examples. It focuses on how the store looks and works for the buyer. If you need the list of features a store should have, read our separate online store features checklist. Both topics come together in our ecommerce development services, where design and functionality are planned as one product.

Why design drives ecommerce revenue

In ecommerce, design decisions show up directly in the numbers. Every friction point, from a confusing menu to an extra form field, removes a share of buyers from the funnel.

The metrics that design affects most:

• Conversion rate. The share of visitors who place an order. Clear navigation, strong product pages and a simple checkout move it the most.

• Cart abandonment rate. According to Baymard Institute, which has studied ecommerce usability for over a decade, the average documented cart abandonment rate is around 70 %. Part of this is unavoidable (people compare prices or save items for later), but Baymard’s research consistently shows that a significant share is caused by checkout design: extra costs that are too high (shipping, taxes, fees), forced account creation, long or complicated forms and lack of trust.

• Average order value. Related products, bundles, clear delivery thresholds and well-designed upsells raise it without pushing buyers away.

• Bounce rate. A homepage or category page that does not answer “Am I in the right place?” in a few seconds loses visitors before they see a single product.

This is why ecommerce conversion rate optimization (CRO) is mostly design work. It is a cycle of finding friction, fixing it and measuring the result. Many of the principles we use come from adjacent industries. For example, fintech products have strong patterns for trust and clarity, which we described in our article on UI and UX principles for ecommerce products.

Homepage and navigation best practices

The homepage has one job: help each visitor find their path into the catalog. It is not a brochure.

Clear value proposition. In the first screen, the visitor should understand what you sell, for whom and why buy here: free delivery, own production, wide range, expert advice. One sentence and a strong visual work better than a rotating carousel of five banners that nobody reads.

Information architecture. The category structure should follow how buyers think, not how your warehouse is organized. Test category names with real users, use their words, and avoid catalog depth beyond three levels where possible.

Mega menu for large catalogs. A well-designed mega menu shows the main categories and key subcategories in one view, with clear grouping. Avoid hover menus that disappear when the mouse moves slightly, and make sure the menu works with keyboard and touch.

Category pages. These are often the real landing pages from search and ads. They need a short description, visible filters, subcategory shortcuts and a product grid that shows the main information at a glance: photo, name, price, rating and key attributes.

Breadcrumbs. They show where the buyer is and help them move one level up without starting over. They also help search engines understand the structure.

Visible search. In stores with more than a few dozen products, search is the main navigation tool for a large share of visitors. Make the search bar a full field in the header, not a small icon.

These are the navigation basics. The homepage then adds the elements that help returning customers: recently viewed items, current offers, popular categories and quick access to the account and orders.

Seasonal and promo pages. Sales periods such as Black Friday or holidays need landing pages that load fast, show the offer clearly and lead directly to filtered products. Design a reusable template once, so marketing can launch a new campaign page in hours rather than asking for a new design each time.

Search and filtering UX

Good ecommerce UX helps the buyer find the right product in one or two steps. Search and filters do most of this work.

Autocomplete. Suggestions should appear after the first characters and include products, categories and popular queries, ideally with a thumbnail and price. This shortens the path and corrects vague queries.

Typo tolerance and synonyms. Buyers misspell brand names, use local terms and switch keyboard layouts. Search should understand “iphone” and “айфон”, “sneakers” and “trainers”, or a model number typed without the dash.

Faceted filters. Filters should match the category: size and color for clothing, power and dimensions for tools, compatibility for spare parts. Show the number of products for each filter value, keep selected filters visible and let buyers remove them with one tap.

Sorting. Price, popularity, rating and newest are standard. The default sort should reflect what buyers in this category usually want, not what the store wants to sell.

Zero-results page. “Nothing found” is a dead end. Suggest corrections, show related categories, popular products and a way to contact the store. Every zero-results query is also data about what buyers expect from your catalog.

Product page design best practices

The product page is where the decision happens. It has to answer every question a buyer would ask a salesperson in a physical shop. The practices below apply to most catalogs. You can see how we apply them on our retail and ecommerce page.

Product images and video

Before: one small photo on a white background, no zoom.

After: an image gallery with several angles, zoom on desktop and pinch-to-zoom on mobile, a photo of the product in use, a short video where the product needs demonstration, and a 360° view for items where shape and details matter.

User-generated content, such as customer photos in reviews, adds credibility that studio shots cannot. It shows how the product looks in real life, on real people, in real homes.

Product descriptions and specifications

Before: a block of marketing text copied from the manufacturer, with key specs hidden in the middle of a paragraph.

After: scannable copy that starts with the main benefits, followed by a specification table with consistent fields across the category. For clothing and footwear, size guides with real measurements and fit notes. For technical products, compatibility information and downloadable documentation.

Write descriptions for the questions buyers actually ask. Support tickets, reviews and search queries are the best source for them.

Price, stock and delivery information

Before: price visible, but stock status unclear and delivery cost only shown at checkout.

After: price transparency, including any discounts and what the final price includes, a clear stock availability status, and a delivery estimate near the add-to-cart button: “In stock, delivery tomorrow” or “Ships in 3–5 days”. If delivery is free above a certain amount, say so here.

Surprises at checkout are one of the main reasons people abandon carts. The product page is the place to remove them.

Reviews and social proof

Before: no reviews, or reviews buried at the bottom of a long page.

After: an average rating with the number of reviews near the product name, a distribution of ratings, filters by rating and attributes such as size or use case, and customer photos. Q&A sections help buyers ask specific questions and see answers from the store or other customers.

Mark up ratings with Review schema so search engines can show them in results. Never hide negative reviews. A product with only perfect ratings looks less credible than one with a realistic mix.

Add-to-cart button and sticky CTA

Before: a small add-to-cart button that looks the same as “Add to wishlist” and “Compare”.

After: a clear CTA hierarchy: the add-to-cart button is the most visible element in the buy box, secondary actions are visually quieter. On long pages and on mobile, a sticky add-to-cart bar keeps the main action available while the buyer reads reviews or specifications.

After adding to cart, confirm the action clearly and offer two paths: continue shopping or go to checkout.

Variants and out-of-stock items. Size, color and configuration selectors are where many product pages fail. Show available options clearly, cross out or hide unavailable ones instead of letting buyers pick them and see an error, and update the price and photo when a variant changes. When an item is out of stock, do not leave a dead end: offer a “notify me when available” option, show similar products and, if you know it, the expected restock date.

Cart and checkout design

Checkout is where the most money is lost. Each extra field, step or surprise gives the buyer a reason to stop.

Guest checkout. Let people buy without creating an account. Offer account creation after the order, when it is just a password away from the details they already entered. Forced registration is one of the reasons for abandonment that Baymard regularly highlights.

Fewer form fields. Ask only for what is needed to deliver and charge. Combine first and last name where possible, hide the second address line behind a link, and do not ask for the same information twice.

Address autocomplete. Suggesting addresses as the buyer types reduces typing and delivery errors. For markets with pickup points or parcel lockers, show a map or searchable list.

Progress indicator. On multi-step checkouts, show where the buyer is and how many steps remain. Uncertainty about how long it will take is a reason to leave.

Shipping cost transparency. Show shipping costs in the cart, before checkout, or at least an estimate. In Baymard’s research, extra costs that are too high (shipping, taxes, fees) are consistently the top reason for abandonment, and seeing them only at the last step makes it worse.

Express payments. Apple Pay, Google Pay and Shop Pay let buyers skip most of the form by using saved details. On mobile they can turn a two-minute form into a few seconds.

So how many steps should checkout have? There is no fixed number. What matters is the number of fields and decisions. A well-designed one-page checkout and a clear three-step checkout can both perform well, as long as each step is short and the buyer always knows what comes next.

After the payment. The order confirmation page and email are part of the design too. They should confirm what was ordered, the total, the delivery method and expected date, and what happens next. This is also the best moment to offer account creation with one click, a referral or a relevant accessory. A clear confirmation reduces “did my order go through?” calls and builds trust for the next purchase.

Mobile ecommerce design

In most markets, the majority of ecommerce traffic comes from smartphones, and the share of mobile orders keeps growing. Designing for mobile is not about shrinking the desktop version. It is about rethinking the store for a small screen, one thumb and short attention spans. This is the core of mobile-first design, which we explain in a separate article.

Key practices for mobile stores:

• Thumb-friendly navigation. Main actions in the lower part of the screen, tap targets large enough for a finger, enough spacing between links.

• Fast pages. Mobile connections vary. Compress images, load below-the-fold content lazily and keep scripts light.

• Sticky add-to-cart. The main action should always be one tap away on product pages.

• Filters that work on mobile. A full-screen filter panel with clear “Apply” and “Reset” buttons, and the number of results visible before applying.

• Mobile checkout. Correct keyboard types for each field (numeric for phone, email keyboard for email), autofill support, express payments and no tiny checkboxes.

Test on real phones, not only in browser emulators. Many mobile issues, like a keyboard covering the “Continue” button, only appear on actual devices.

Trust signals and accessibility

Buyers hand over money and personal data to a store they may have found five minutes ago. Trust has to be earned on every page.

Trust signals:

• Clear return policy. Visible on product pages and in the cart, not only in the footer.

• Contact details. Phone, email, chat and a physical address show that there are real people behind the store.

• Trust badges. Payment provider logos and security indicators near the payment form. Use only those that are real and relevant.

• Reviews. Both on products and on the store itself.

• Professional design. Consistent visuals, no broken images or obvious errors. Buyers notice details.

Accessibility:

An accessible store works for more people and often converts better for everyone. WCAG 2.2 is the current reference standard. In the EU, the European Accessibility Act has applied to ecommerce services since June 2025, with an exemption for microenterprises. Key points:

• Sufficient color contrast for text and buttons

• Alt text for product images that describes what matters

• Full keyboard navigation, including menus, filters and checkout

• Clear form labels and error messages that explain how to fix the problem

• Focus states that show where the user is on the page

Consistent visual design system

As a store grows, new pages, banners and features appear every month. Without a system, the interface slowly becomes a patchwork of different button styles, font sizes and spacing.

A design system solves this. It is a shared set of rules and components:

• UI kit. Buttons, inputs, product cards, badges, filters, modals and other components in all their states.

• Typography. A limited set of text styles for headings, body text, prices and labels.

• Color palette. Brand colors plus functional colors for sale prices, stock status, errors and success messages.

• Component consistency. The same product card looks and behaves the same in the catalog, search results, recommendations and the cart.

For buyers, consistency means they learn the interface once and then move through it without thinking. For the business, it means new pages are faster to design and build, and A/B test results are easier to apply across the store. A UI built on a system also makes accessibility easier to maintain. Our UI/UX design services include creating and documenting design systems for stores and digital products.

How to test and improve your store design

Even the best practices are a starting point, not a final answer. Every store has its own audience, products and friction points. The way to find them is data.

Analytics. GA4 funnel exploration shows where buyers drop off between product page, cart, checkout steps and purchase. Start with the biggest drop.

Heatmaps and session recordings. Tools such as Hotjar and Microsoft Clarity show where people click, how far they scroll and what they do just before leaving. They often reveal problems that analytics cannot, like a promo code field that sends people off to search for coupons.

Usability testing. Watching five to eight real users try to complete tasks in your store reveals most of the major usability problems. It is fast, inexpensive and often eye-opening for the team.

Search analytics. Internal search queries show what buyers are looking for in their own words. Queries with zero results, frequent reformulations and searches for products you already stock but name differently are direct input for category names, synonyms and new filters.

Customer feedback. Support tickets, chat logs, return reasons and reviews tell you where the store fails to answer questions. If many buyers ask about sizing, the size guide is not working. If returns often say “looked different in the photo”, the images need work.

A/B testing. Once you have a hypothesis, test it. Change one meaningful thing, such as the checkout layout or product page structure, and compare results on enough traffic to reach statistical significance. Small cosmetic tests rarely produce reliable results in stores with modest traffic.

The cycle is simple: measure, find the biggest friction point, fix it, measure again. A practical way to keep it going is a short list of design practices adapted to your store, reviewed every quarter: which ones you already follow, which ones you tested, and which ones are next in line. Stores that run this cycle consistently improve conversions every quarter, while stores that redesign everything at once every few years often lose what was already working.

What to improve first. If you have a long list of possible changes, prioritize by where money is lost. Start with checkout and cart, because problems there affect buyers who have already decided. Then product pages for your best-selling categories, then search and filters, then the homepage. A single fix in checkout often matters more than a full homepage redesign.

Ecommerce website design examples

Looking at strong stores is useful, as long as you look for patterns rather than copying visuals. Most lists of examples focus on how stores look. We prefer to look at what they solve. Here are several B2C and B2B stores and what each does well.

Amazon: product detail page and reviews. Few people would call Amazon beautiful, but its product detail page is a reference for completeness. Buy box with price, delivery date and stock status, extensive reviews with photos and filters, and customer questions and answers. Every element answers a buyer’s question.

IKEA: navigation and inspiration. IKEA combines a clear category structure with room-based inspiration. Buyers can shop by product type or by room, and products in inspiration images lead directly to product pages. It is a good example of serving both buyers who know what they want and those who are still exploring.

Apple: product storytelling. Apple product pages explain complex products through visual storytelling, then move to a clean, step-by-step configuration and checkout. The pattern works for any store with configurable or high-consideration products.

Zalando: filters and sizes. For fashion, Zalando shows how detailed faceted filters, size information and clear return conditions reduce uncertainty when buyers cannot try items on.

Grainger: B2B catalog. Grainger, a large US industrial supplier, is a strong B2B example: detailed specification tables, precise filters for technical attributes and fast ordering for buyers who know part numbers. B2B stores need efficiency more than inspiration.

Buddha Pizza: brand and ordering from our portfolio. For Buddha Pizza, a pizzeria brand from Odesa, we designed and built an ordering experience where a strong brand character goes together with a fast path to the order. The project received design awards and was widely shared in local social media, which shows that a store can be both distinctive and practical.

When collecting inspiration, keep a simple log: what the pattern is, which problem it solves and whether that problem exists in your store. That turns inspiration into a backlog of design patterns you can test.
