How to make a success of your e-commerce website redesign.

We speak to a lot of business owners about e-commerce website redesign. And almost all come to the conversation with the same mix of excitement and anxiety.

The excitement, because a new e-commerce website could mean more sales, better rankings and a brand that finally looks the part.

The anxiety, because when you already have a live store generating sales, a redesign feels like a risky undertaking. There are rankings to protect, loyal customers to consider, investment to justify and a lot that could go wrong.

We get the concern. And we spend a lot of time reassuring clients that those risks are real — but manageable.

Because most redesign problems aren’t a case of bad luck. They’re the result of mistakes — mistakes you can avoid when you follow the right website redesign process.

This guide is essentially what we tell them. What a well-executed e-commerce redesign can do for your business, the pitfalls to watch out for and how to run a redesign that delivers the results you’re looking for.

What can an e-commerce redesign do for your business?

Every growing e-commerce business reaches a point where its current website starts holding it back. If you’re at that point right now, here’s what a well-planned redesign can achieve.

• More sales. Website improvements — like a better user experience, clearer product pages or a smoother checkout — help to boost your conversion rate. If you’re currently getting traffic but not enough sales, your site’s design and UX are often where the problem lies.
• Better SEO performance. A redesign is an opportunity to fix technical SEO issues, improve site speed, refine your content structure — and if it’s been a while — bring your site in line with what search engines (and AI engines) now expect from a modern, well-maintained website.
• Improved scalability. If your current platform is creaking under the weight of your product catalogue, your marketing ambitions or your traffic levels, a redesign is a chance to rebuild on foundations that can really support your growth.
• Stronger brand credibility. The average website lifespan varies. But most business websites start to feel dated after two to three years. If your online store looks like it hasn’t been touched in the last decade, you’re definitely not giving the best impression to potential customers. A fresh, modern redesign builds engagement and trust.

Why e-commerce website redesigns sometimes fail

When you revamp a website, there’s a lot to gain. But also a lot at risk. You can minimise that risk by learning from the mistakes business owners — and inexperienced web designers — commonly make.

When an e-commerce redesign goes wrong, it’s usually for one of the following reasons.

Redesign mistake #1: No clear goals

Redesigning because the site looks a bit tired, because a competitor has a new flashy website or because you want to keep up with the latest web design trends isn’t a good enough strategy.

Without specific, measurable goals, there’s no way of knowing whether the redesign has worked — and no north star guiding design and development decisions along the way.

Redesign mistake #2: Ignoring the data

Your current website, however imperfect, is a goldmine of information about how your customers behave. Which pages do they spend time on? Where do they drop off? What does your checkout abandonment rate look like?

Redesigning without this insight means you’re just guessing — and you risk rebuilding the same problems into the new site.

Redesign mistake #3: Neglecting SEO

This is one of the most common and painful redesign mistakes. Issues like a new URL structure, removed pages, or missing redirects can cause significant drops in organic traffic that can be hard to recover from. You need a clear plan for protecting SEO when redesigning your site.

Redesign mistake #4: Designing for aesthetics over conversion

There’s no point in a beautiful website that doesn’t actually sell. Design decisions need to be driven by what helps customers find products, trust your brand and complete purchases quickly — not just what looks good.

Redesign mistake #5: Rushing the launch

Going live before the site has been properly tested can leave broken links, payment issues and other customer experience problems unresolved — and this can actively damage your brand.

Research shows that nearly a quarter of customers will stop purchasing from a brand after only one bad experience.

How to run a successful e-commerce website redesign: step by step

So how do you enjoy the benefits of an e-commerce website redesign while avoiding the pitfalls?

You can make a success of your new and improved online store by following our tried-and-tested website redesign process.

Step 1. Start with clear business goals

Before designers get to work, be clear on what you’re trying to achieve. More sales? A higher average order value? Lower bounce rates? Better mobile performance? Reduced cart abandonment?

The more specific you can be, the better. “Improve conversions” is useful as a starting point. But you need to go further. “Increase our checkout completion rate from 58% to 70% within six months of launch” is something you can design towards — and measure against.

Step 2. Audit your current website

Your existing site is full of useful information. So before starting an e-commerce redesign, audit what you have.

Dig into your analytics. Which pages get the most traffic? Which have the highest exit rates? Where do people drop off in the purchase journey? What’s your current conversion rate on key pages, and how does it compare to industry benchmarks?

Keep in mind: the goal isn’t just to spot problems. You also want to identify what’s working, so you don’t accidentally throw away the good stuff as part of your website revamp.

Step 3. Understand your customers

The best e-commerce websites are built (and redesigned) with a laser focus on the brand’s customers.

Who are they? How do they find you? What devices do they shop on? What questions do they have before buying? What puts them off? What makes them trust a new brand enough to hand over their payment details?

If you have the means to gather direct feedback — a short survey, customer focus groups, user testing on your current site, existing feedback or support tickets — this is the time to do it.

It’s also worth thinking carefully about how different you want the redesign to feel. If you have a loyal customer base, used to the current look and layout of your website, changing things dramatically can lead to confusion and frustration.

You may like to keep familiar flows intact, update rather than completely overhaul your website branding and — as you approach your launch date — communicate the reasons behind any changes to users.

Smaller, well-considered changes can still make a big impact without alienating the customers who already love your brand.

Step 4. Prioritise conversion-focused UX design

It doesn’t matter how good-looking your website is. If customers find it hard to use, they won’t buy. This is why user experience design should be at the centre of every design decision.

That means thinking carefully about:

• Navigation. Can customers find products quickly and intuitively? Clear, logical website navigation reduces friction and keeps people moving towards a conversion.
• Performance. Customers expect an e-commerce website to load within two seconds — and slow loading times cost sales as well as rankings.
• Responsive design. Nearly three-quarters of e-commerce site visits now come from mobile devices. Your redesign needs to work beautifully across all of them. Responsive web design is non-negotiable.
• Accessibility. The best e-commerce websites can be used by anyone. They provide extra functionality for users with additional needs by sticking to website accessibility guidelines.

Step 5. Optimise the most important website elements

Some website elements carry more weight than others. Follow e-commerce website best practices to ensure your hero section, product pages, calls to action and checkout all drive visitors towards a conversion.

Homepage hero section. Your website hero section is an opportunity to share your value proposition, a space to tell a story and sell your brand. But don’t pack it so full of heavy assets that it slows your site to a crawl.

Product pages. Clear imagery, honest descriptions, transparent pricing, prominent add-to-cart buttons and well-placed trust signals — like reviews, guarantees and returns policies — all give shoppers the confidence they need to buy.

Calls to action. Every page should have a clear next step. Effective and eye-catching CTAs tell customers exactly what to do, why it’s worth doing and what they can expect to happen next.

Checkout. Follow e-commerce checkout best practices to minimise abandonment. That means guest checkout, multiple payment options, minimal steps and clear progress indicators.

Step 6. Consider SEO carefully

A redesign can either strengthen or seriously damage your organic search performance. The difference comes down to how carefully SEO is handled throughout the process. At a minimum, you need to:

• Map all existing URLs and ensure every page with search visibility gets a proper 301 redirect to its new equivalent.
• Protect high-performing pages — don’t delete or significantly alter pages that currently rank well and drive website traffic.
• Plan your data migration carefully — accurately transfer products, categories, customer accounts, order history and reviews, keeping customer journeys intact.
• Preserve your existing metadata — things like page titles and meta descriptions — or improve them deliberately.
• Maintain your site structure — avoid restructuring your URL hierarchy unnecessarily, especially for high-performing pages.
• Update your sitemap — after changing the structure of your site or any URL slugs, update your sitemap and submit it to search engines.

Also, bear in mind that even if you handle SEO considerations well, a period of ranking volatility is not uncommon following an e-commerce redesign. Search engines have to recrawl and reindex the site, and this process can last anything from a couple of weeks to a couple of months.

For this reason, it’s wise to plan an e-commerce website redesign for a quieter trading period. You don’t want to go into peak season with a website that isn’t operating at its best.

Step 7. Build with scalability in mind

Your website shouldn’t just solve the problems you’re experiencing today. It should give your business room to grow.

Think about where you want your business to be in two or three years. More products? New markets? A loyalty programme or subscription service?

The architecture and platform choices you make now will determine how easy — or difficult — those expansions are.

Step 8. Test before you launch (and after)

Go live with broken functionality, payment errors or a checkout process that feels clunky on mobile, and you’ll likely lose customers and sales.

Before launch, you need to test everything: every page, form, product filter, payment method, email trigger — across every device and browser.

You should also run an SEO audit, looking for things like broken links, overly long title tags and missing alt text. Then, fix any issues you find.

Quality assurance in web design isn’t the most exciting part of the process. But it really does determine whether launch day is a time of celebration or of crisis.

After launch, keep a close eye on your analytics and error logs for the first few weeks and months. Anything that was missed in testing will surface once real customers start using the site, giving you another chance to rectify and improve.

Step 9. Measure success post-launch

You defined what e-commerce website redesign success would look like back in step one. Once your new website goes live, you can start tracking your progress towards those goals.

Measure over a realistic timeframe — some changes take weeks to show their full impact, particularly on the SEO side of things. And use what you find to keep improving the site after launch.

A redesign is a big step in the right direction. But the best e-commerce stores are always being analysed and optimised, to create a better experience for users and more sales for your business.

A few easy e-commerce wins if you’re not ready for a full redesign just yet

A full e-commerce website redesign isn’t always the best next step — particularly if budget or timing isn’t right. If you want to improve your e-commerce conversion rate in the short term, it’s worth making targeted improvements to the following website elements:

Product copy and imagery. Are your product descriptions and images giving customers the information they need to make a decision? If not, work to improve them.

Review and simplify your checkout. Work with a web developer to cut unnecessary steps, add guest checkout, add autofill functionality — anything that makes the process quicker and more convenient for customers.

Add or update trust signals. Incorporate reviews, guarantees, security badges or user-generated content to reassure customers that your brand is legit.

Check your site speed and fix any obvious issues. Use Google’s Core Web Vitals tool to find and fix any obvious page speed issues. Optimising images and deleting unnecessary plugins could make a big difference to load times.

Review and test your CTAs. Play around with CTA copy, colours and placement. Small tweaks here can make a big difference to click-through rates.

FAQs

How much does an e-commerce website redesign cost?

It depends on the size and complexity of your store, the platform you’re building on and the agency you work with.

The cost of a small e-commerce website redesign, including design and development, typically starts at around £10,000. A large, feature-rich store with complex integrations will cost considerably more. The more clearly you can define your requirements upfront, the more accurate a quote you’ll get.

Our recommendation? Be wary of very low quotes. A redesign that cuts corners on UX, performance or SEO will cost you more in lost sales than you saved on the build.

How long does an e-commerce redesign take?

It varies. A straightforward redesign of a small store might take six to eight weeks. A larger, more complex project could run to several months.

Some of this depends on the capacity of your web design and development team. But you, as the client, can help keep things running to plan by supplying website content, feedback and approvals as scheduled.

What’s the difference between an e-commerce website redesign and a website refresh?

A redesign typically involves rebuilding the site from the ground up — new design, new build, potentially a new platform or CMS.

A refresh is more limited in scope: updating the visual design, improving specific pages or adding new functionality without a full rebuild.

Refreshes are quicker, cheaper and lower risk. Redesigns allow for more fundamental improvements. Which is right for you depends on what’s actually holding your current site back.

Can I use AI to redesign my e-commerce website?

In short, no. Designing and building a high-performing e-commerce website requires strategic thinking, technical expertise, empathy for your customers and iterative testing that AI tools can’t replicate.

A site built on AI-generated design, SEO advice and content will almost certainly underperform one built by an experienced web design and development company.
