Your website is the most important asset in your digital marketing ecosystem. It is where first impressions are formed, trust is built, and revenue is generated. Byter Digital is a specialist web design agency in London. We create websites that balance stunning visual design with technical performance. We add a strong SEO foundation and conversion optimisation that turn visitors into customers. Every site we build looks beautiful, loads fast, and drives measurable business results.
We work across all major platforms, including WordPress, Shopify, Wix, Squarespace, and HubSpot CMS. We also offer custom builds using Next.js and React for businesses that need maximum performance and flexibility. You might be a Mayfair restaurant needing an elegant brand showcase. You might want a high-converting Shopify store, or a lead-generating WordPress site. Whatever your goal, our London design team delivers solutions tailored to your commercial objectives.
What separates Byter from other web design agencies in London is our integrated approach. We do not just design websites. We build them with SEO architecture baked in from day one. We apply conversion rate optimisation principles to every page. We configure and test integrations with your CRM, booking systems, and marketing tools before launch. Our clients do not receive a pretty website that sits idle. They receive a commercial tool that actively drives their business forward.
We are based at 33 Cavendish Square in Mayfair, and we work closely with clients across London. We start with wireframes and design concepts created in Figma. We then move through development, content population, testing, and post-launch support. We believe the best websites are built through genuine collaboration. Our process keeps you involved at every stage, without burdening you with technical complexity.
UX Design and Conversion Architecture
Every website we build starts in Figma. Our UX designers map out user journeys, wireframe key pages, and prototype interactive elements. We do this before a single line of code is written. This design-first approach positions navigation, content hierarchy, and calls-to-action to guide visitors towards conversion. That might mean making a purchase, booking a table, submitting an enquiry, or calling your team.
We apply proven conversion rate optimisation principles to every page. These include clear value propositions above the fold and well-placed trust signals like testimonials, client logos, and accreditations. We also use friction-reducing form designs and mobile-first layouts that perform flawlessly on every device. For most London businesses, mobile traffic exceeds 65% of total visits. So our mobile-first approach is not optional. It is essential.
Our designers draw on data from over 200 website projects for London businesses. This informs every layout decision. We know which hero section formats drive the highest engagement for restaurants. We know which form designs generate the most leads for professional services. We know which product page layouts convert best for e-commerce. This experience-backed design process delivers results from day one.
Platform Expertise: WordPress, Shopify, and Beyond
Choosing the right platform is a critical decision. It affects your website's performance, scalability, and total cost of ownership. Our London team has deep expertise across WordPress, the world's most popular CMS, powering 43% of all websites. We also know Shopify, the leading e-commerce platform. For businesses needing maximum speed and flexibility, we use modern frameworks like Next.js.
For WordPress projects, we build custom themes using Elementor Pro, Gutenberg blocks, or fully bespoke theme development. The choice depends on your team's technical capability and content management needs. For Shopify, we create custom storefronts using Liquid templating. We integrate with payment processors and configure automated fulfilment workflows. For HubSpot CMS, we build marketing-integrated websites. These connect smoothly with your CRM, forms, and automation workflows.
We also offer Wix and Squarespace development for London businesses that need a cost-effective, easy-to-manage solution. Our developers customise these platforms far beyond their templates. We deliver unique, branded experiences that stand out from the crowd. Whatever the platform, every site we build is optimised for speed, SEO, and accessibility.
SEO-First Architecture
A beautiful website that cannot be found on Google is a beautiful waste of money. Every website we design and build in London includes SEO architecture as a foundational element, not an afterthought. This covers logical URL structures and optimised heading hierarchies. It includes schema markup (LocalBusiness, Organisation, BreadcrumbList, Product). It also covers fast page load times, proper image optimisation, and mobile-first responsive design.
We work closely with our SEO team from the very start of the design process. Keyword research informs site architecture, page titles, meta descriptions, heading tags, and content structure. For London businesses targeting local search, we configure Google Business Profile integration and local schema markup. We also build location-specific landing pages. These help you rank for searches like 'web design agency London' or 'restaurant near Mayfair'.
Post-launch, we run a thorough SEO audit using Screaming Frog and Google Search Console. We verify that every page is properly indexed and all technical SEO elements are correctly implemented. The site is then ready to start climbing search rankings immediately.
Performance, Security, and Ongoing Support
Page speed directly impacts conversion rates. Every additional second of load time reduces conversions by an average of 7%. Our London web development team builds sites that consistently score 90+ on Google PageSpeed Insights. We achieve this through lazy loading, image compression (WebP/AVIF formats), efficient code splitting, CDN configuration, and server-side caching.
Security is equally critical. We implement SSL certificates and configure security headers. We apply WordPress hardening or Shopify security best practices. We set up automated backups and monitor for vulnerabilities. Our managed hosting clients enjoy 99.9% uptime. This is backed by proactive server monitoring and rapid incident response.
We offer ongoing website support and maintenance packages for London businesses that want peace of mind. These cover plugin and theme updates, security monitoring, performance optimisation, content updates, and priority support for any issues that arise. Your website is a living asset. It needs ongoing attention to remain secure, fast, and effective.
Our Process
How We Work
Our proven process delivers consistent results for London businesses
Discovery and Requirements
We begin with an in-depth discovery session at our Mayfair office or via video call. We explore your business goals, target audience, competitor space, brand guidelines, technical requirements, and integration needs. This defines a clear project brief.
UX Wireframing and Architecture
Our UX designers create detailed wireframes in Figma. These cover site architecture, page layouts, navigation structure, and user flows. We map out the conversion journey and establish the information hierarchy before visual design begins.
Visual Design and Prototyping
We design high-fidelity mockups in Figma for all key page templates, including desktop and mobile views. Interactive prototypes let you experience the site before development begins. You can provide feedback on every detail.
Development and Integration
Our developers build the site on your chosen platform, whether WordPress, Shopify, HubSpot CMS, or custom. We use clean, performant code. We integrate your CRM, booking systems, payment processors, and marketing tools during this phase.
Content, Testing, and QA
We populate the site with your content and optimise all images and metadata for SEO. We then test thoroughly across devices, browsers, and screen sizes. We verify accessibility, performance, and functionality before launch.
Launch and Post-Launch Support
We manage the full launch process. This includes DNS configuration, SSL setup, analytics verification, and search engine submission. Post-launch, we provide 30 days of priority support, followed by optional ongoing maintenance packages.

How long does it take to design and build a website?

Our project managers keep everything on track with weekly updates and clear milestones.
Which platform do you recommend: WordPress, Shopify, or something else?
It depends entirely on your business needs. WordPress is our default recommendation for content-heavy sites, blogs, and businesses that need maximum flexibility. Shopify is the clear winner for e-commerce. HubSpot CMS is ideal for B2B companies already using HubSpot for marketing and sales. Wix and Squarespace suit smaller businesses with limited budgets. For maximum performance and scalability, we recommend Next.js. We assess your requirements during discovery and recommend the best fit for you.
Will our new website be SEO-friendly?
Every website we build includes full SEO architecture as standard. This covers optimised URL structures, heading hierarchies, meta titles and descriptions, and schema markup. It also covers image alt text, XML sitemaps, robots.txt configuration, Core Web Vitals optimisation, and mobile responsiveness. We also set up Google Search Console and submit your sitemap for indexing. For businesses wanting ongoing SEO work post-launch, we offer dedicated SEO retainers.
Can you redesign our existing website without losing our Google rankings?
Yes, this is something we handle regularly for London businesses. We implement a careful migration plan. It includes URL mapping, so we keep all existing URLs or set up proper 301 redirects. We preserve all meta data and maintain content quality. We then submit the updated sitemap to Google Search Console. Our SEO team monitors rankings throughout the migration and addresses any fluctuations quickly. Most clients see rankings improve post-migration thanks to better technical performance.
Do you provide website hosting and ongoing maintenance?
Yes. We offer managed hosting packages starting from £75 per month. These include high-performance hosting with 99.9% uptime and daily automated backups.

Integration is included in our standard development process. We configure and test everything before launch.
Will we be able to update the website ourselves after launch?
Yes. Every site we build includes a user-friendly content management system, whether WordPress, Shopify, or your chosen platform.
