Responsive Web Design and Development Services
Our responsive web design and development services build you a website that works on every device a visitor might open it on. Not a desktop website squeezed onto a phone, where half the content is unusable for the people most likely to be looking.
One website, one address, a layout that rearranges itself to fit whatever is in your customer's hand.
“It looks great on the desktop. On my phone it looks terrible.”
That sentence turns up on forum after forum, almost word for word. Entrepreneurs post it about their own websites, usually late at night, and usually after opening it on their own phone for the first time and realising that the design they loved on a laptop has fallen apart on a phone screen.
The complaints are almost always the same: the navigation bar is messed up, the text is cut off, buttons are impossible to tap, and parts of the website are practically unusable.
Here is what makes it expensive, and nobody tells you this. No customer will email you to say your booking button was hanging off the edge of their screen, or that they gave up because they had to pinch and drag just to read your prices. They simply leave. You will never know about the lead you never got. It will be just another quiet week. So the website, instead of bringing in more and more customers, keeps silently costing you without you knowing.
69.9%
of all website visits come from phones
2.0%
mobile conversion, against 3.4% on desktop
−32%
cost per customer after one rebuild
The numbers give this silent killer of conversions its shape. Contentsquare's 2026 benchmark covers 99 billion sessions across more than 6,500 websites. Phones account for 69.9% of all visits. Yet those visits convert at around 2.0%, compared with 3.4% on desktop. People browse on their phone and then buy somewhere else, or not at all.
Speed makes it worse, and phones are where speed hurts. Akamai measured 27.7 billion sessions and found that one hundred milliseconds of extra delay cut smartphone conversion by 7.1%. Mobile bounce nearly doubled between a page that loaded in 0.7 seconds and one that took 2.7. Deloitte, working with Google across 37 brands and 30 million sessions, found the reverse also holds: take a tenth of a second off mobile load time and retail conversion rises 8.4%.
We watched this play out with Grand Car Sale. They were paying 36,000 euros a year for a slow, bloated website that barely produced leads. We rebuilt it. Their cost per customer fell by 32%.
Two websites you can open on your phone right now
Voice Karaoke is a club in Limassol, Cyprus. Think about how somebody decides to go: it is Friday, they are already out, they are standing on a pavement with a phone in one hand. That decision never happens at a desk.
On mobile, the problem became impossible to ignore. Their old website was trying to squeeze a layout that had never been designed for a small screen into a phone-sized viewport. Body text disappeared beyond the right edge, sometimes cutting words in half. The reservation button, arguably the most important button on the entire website, sat partly off-screen.
The same club, the same phone, one year apart.
You do not have to take our word for it. The old website is still online. Open both on your phone and try to do the thing a customer would do: book a table for Friday.
The rebuilt website took its first bookings on day two after launch.
What our responsive web design services cover
Responsive is not a switch somebody flicks at the end of the build. It is a series of deliberate decisions made while the website is being designed and developed. Skip enough of them and you end up with the websites in the section above. Here is what we actually do.
Mobile-first layout
We design for the smallest screen first, then let the layout expand into tablet and desktop. When desktop comes first, mobile easily becomes an exercise in squeezing, hiding and rearranging whatever was already designed for a much larger screen. That is why so many websites look considered on a laptop and improvised on a phone.
Breakpoints that follow your content
A breakpoint is the width at which a layout rearranges itself. Instead of choosing three standard device sizes and hoping everything works between them, we put breakpoints where your content actually starts to strain, which is a different set of widths for a car catalogue than for a booking page. The result is a layout that never looks stretched or cramped at the sizes in between.
Fluid type and images
Text scales with the screen so it stays comfortable to read across different widths, rather than looking right at only a handful of preset sizes. Images are served at the size the device needs, so a phone on mobile data is not downloading a picture built for a 27-inch monitor on home wifi.
Touch targets and thumb reach
A cursor can hit something a few pixels wide. A thumb cannot. We size buttons and interactive elements for touch, leave enough space between them, and keep the important actions within easy reach on a small screen. On a booking button, a lead form or a checkout, those details are the difference between somebody completing the action and abandoning it halfway through.
Performance on a real phone
We test how the website behaves on a real phone on mobile data, where large images, unnecessary scripts and heavy animations stop being invisible. A website that feels instant on office wifi can feel like a different product entirely to somebody on one bar of signal in a car park.
Real-device testing
Every build is checked on physical iOS and Android devices before launch. Browser previews are useful, but they do not reproduce every behaviour of real hardware. Screen dimensions, browsers, operating systems, keyboards and touch interactions all expose problems that never appeared during desktop development.
Accessible foundations
Readable contrast. Text that can be enlarged without breaking the layout. Navigation that does not depend entirely on a mouse. Buttons with clear labels and enough space around them. These decisions make the website easier to use for people with accessibility needs, and they make it easier to use for everybody else at the same time.
Thought about from the beginning, all of this is simply how the website gets built. Retrofitted later, it becomes a project of its own.
How we build it
For most websites, it takes around three weeks from the first call to launch.
- 01
We talk. You tell us what the business needs and what the website is failing to do. We tell you honestly whether we are the right people for it.
- 02
We scope it. You get the approach, the deliverables and the price in writing before anybody starts work. Once the scope is agreed, the price does not increase halfway through the project.
- 03
We research and write. What your customers search for, what your competitors claim, what your pages have to say to beat them. The copy comes before the design, because a layout built around real words is a different thing from a layout that gets words poured into it.
- 04
We design and build. Phone first, then everything bigger.
- 05
We test. Real devices, real connection speeds, and every important form and user journey tested from beginning to end.
- 06
We launch and hand over. Analytics and conversion tracking are wired in from day one, so you can see what people actually do on the website instead of guessing.
Selected work
Two projects where getting mobile right changed the entire business performance.
Why work with us
You own everything
If you decide to leave, nothing is licensed back to you or hidden behind an agency account. From day one, the website is your asset.
No lock-in of any kind
If you want to host somewhere else, we move you off our hosting for free. We would rather keep clients because the work is good than because leaving is difficult.
One team, start to finish
Research, offer, copy, design, development, tracking and hosting, all in one place. No handing a copywriter's document to a designer who hands a file to a developer, and no four suppliers pointing at each other when something breaks. The same team that understands why the website is being built is the team that takes it live.
What we build with, and how we check it
Once a build is finished it gets measured, not eyeballed. We check every page against Google's Core Web Vitals: largest contentful paint under 2.5 seconds, interaction to next paint under 200 milliseconds, cumulative layout shift under 0.1. Those three numbers are used by Google's ranking systems, and more usefully they are a decent proxy for whether a website feels fast to somebody holding a phone on a patchy connection.
We run those checks in Lighthouse and PageSpeed Insights, then confirm the result on real hardware. Lab tests expose problems before launch, but they do not reproduce every part of a real visit. A page can score well in a controlled test and still feel slow in somebody's hand. That last test is the one your customer experiences.
Questions we get asked
One website whose layout adapts to whatever screen it is opened on, rather than a separate mobile website or a desktop design shrunk down to fit. Same address, same content, same website. The layout rearranges itself: columns stack, menus collapse, images resize, and text stays readable without anybody pinching or scrolling sideways.
Because most people see you on a phone before they see you anywhere else. If their first impression is cut-off text and a button they cannot reach, the visit ends there, and you never learn it happened. On phones, visitors already convert at roughly half the rate they do on desktop. A website that fights them on top of that makes the gap worse.
Two ways, both free. Open it on your phone and try to do the thing you want a customer to do: book, call, buy, submit a form. If you have to zoom or drag sideways at any point, you have your answer. You can also inspect the page source for a viewport tag using width=device-width. A responsive website will normally have one, but the tag alone does not prove the website is responsive. The layout still has to adapt properly around it.
Mobile-friendly only means a website is usable on a phone, which a shrunken desktop layout can technically claim while still being miserable to use. Responsive means the layout is genuinely rebuilt at each screen size. A separate mobile website on its own address, like m.yoursite.com, is a third option, and Google recommends against it because you then maintain two websites that drift apart.
Yes, although not as a standalone ranking bonus. Google indexes the mobile version of your website, so whatever is missing or broken on the phone version is what Google actually sees and ranks. Since July 5, 2024, Google has crawled websites for Search using its smartphone crawler. If your content cannot be accessed at all from a mobile device, Google says it cannot be indexed.
Sometimes it can be repaired. It depends on how the original was built: if the underlying layout uses fixed widths, patching it usually costs more than rebuilding and leaves you with a website that is still old. We look at what you already have first and tell you which situation you are in before you commit to anything.
Around three weeks from the first call to launch, for most websites. Larger builds, product catalogues, integrations and multilingual websites take longer. The timeline goes into the written scope before the project starts, rather than becoming something we discover halfway through.
It depends on the size of the website, the functionality it needs, and how much of the research, strategy and writing we handle. You get a fixed price in writing before any work starts. Once the scope is agreed, the number you agree to is the number you pay.
You do. The source code, website files, design files and domains belong to you. If you want to move it elsewhere later, we help you move and charge nothing for it.
Show us the website you have
Send us the address. We will open it on a phone, try to use it like a customer would, and tell you where it breaks down and what it would take to fix. The first look is on us.
