Responsive & mobile optimisation

Ensuring your website looks and works perfectly on smartphones, tablets and all screen sizes

Mobile devices account for more than half of all web browsing — and a website that doesn't work well on a phone or tablet is a website that's failing more than half its visitors. Responsive design isn't a nice-to-have. It's fundamental. Responsive and mobile optimisation ensures your website delivers the same quality of experience regardless of the device someone uses to access it. Layout adjustments, touch-friendly navigation, appropriately sized typography and images, and performance tuning for mobile connections — so every visitor gets an experience worth staying for.

What Is Our Responsive & mobile optimisation Service

Responsive and mobile optimisation is the process of ensuring a website functions and looks correct across all screen sizes and device types, from desktop monitors to smartphones. It involves reviewing how layouts, typography, images, navigation and interactive elements adapt at different breakpoints, making the technical and design adjustments needed to deliver a high-quality, usable experience on every device — including optimising loading performance for mobile network conditions.

Why Choose Our Responsive & mobile optimisation Service

You need this when you want to know whether a particular design decision, call to action or layout will perform before you commit to it, when two approaches seem equally valid and you want evidence rather than opinion to decide between them, or when your website is performing reasonably and you want a systematic way of improving results incrementally without a full redesign. A/B testing is the discipline of continuous, evidence-based improvement.

What's Included In Our Responsive & mobile optimisation Service

This service includes the design of two or more variants of a specified page element, technical setup of the A/B test, running the test to statistical significance and analysis of results. Delivered as an A/B test report with a clear recommendation and implementation of the winning variant.

More than half of web traffic arrives on a mobile device. A website that doesn't deliver a properly considered mobile experience isn't just a usability issue — it's a commercial one. The businesses that get mobile right don't lose the majority of their audience before they've had a chance to be persuaded.

Why We’re Different

Most marketing companies focus on channels and tactics.
We focus on reaction.

Before selecting platforms, formats, or media spend, we define how your audience thinks, feels, and decides. We use behavioural psychology to understand what will capture attention, build trust, and motivate action — then choose the channels that best support that outcome.

Every channel we use has a clear purpose, a defined role, and a measurable objective. Nothing is done “because it’s popular” or “because it’s expected”.

The result is marketing that feels natural to engage with, works across multiple channels, and is designed to deliver meaningful, long-term results.

The design and technical process of ensuring a website functions correctly, displays appropriately and provides a high-quality user experience across all screen sizes and devices — from desktop monitors to laptops, tablets and smartphones — adapting layout, typography, navigation and interactive elements to suit each context.
Google uses mobile-first indexing — ranking websites based primarily on their mobile version. More than 60% of UK internet traffic comes from mobile devices. A website that performs poorly on mobile loses both search engine rankings and a majority of its potential audience. Mobile quality is now a fundamental commercial requirement.
Responsive design uses fluid grids and CSS media queries so a single codebase adapts fluidly to any screen width. Adaptive design serves distinctly different layouts at specific breakpoints, sometimes with separate mobile templates. Responsive design is the current standard — it is more maintainable and better supported by Google.
Google’s performance metrics assessed specifically on mobile: Largest Contentful Paint (LCP — how quickly the main content loads), Interaction to Next Paint (INP — how quickly the site responds to interaction) and Cumulative Layout Shift (CLS — whether the layout jumps as the page loads). Poor mobile Core Web Vitals directly affect Google rankings.
Tap targets that are too small (buttons and links under 48px touch area), text too small to read without zooming, content wider than the screen (horizontal scrolling), intrusive pop-ups that cover most of the mobile screen, slow loading on mobile network conditions and navigation menus that don’t work correctly on touch.
Google Search Console’s Mobile Usability report (identifying pages with specific mobile issues), Google PageSpeed Insights (mobile-specific performance scores), manual testing on real devices across iOS and Android, Chrome DevTools device emulation for responsive layout checking and Google’s Lighthouse audit for comprehensive mobile quality assessment.
Mobile-first design starts with the mobile layout and progressively enhances for larger screens. Retrofitting mobile means designing for desktop first and then attempting to squeeze the design onto smaller screens. Mobile-first produces better mobile experiences because every design decision is made with the smallest screen constraints in mind from the outset.
Touch requires larger interactive targets (minimum 44–48px), cannot rely on hover states (touch has no hover equivalent), swipe gestures replace scroll and navigation behaviours, and tap precision is lower than cursor precision. Mobile design must ensure all interactive elements are reachable with a thumb and respond visibly to touch.
An HTML tag in the page head that instructs the browser how to control the page’s dimensions and scaling on mobile devices. Without it, mobile browsers render the page at desktop width and scale it down, making text tiny and requiring pinch-zoom to read. Every page must include a correctly configured viewport meta tag.
Images are typically the largest page elements and the primary contributor to slow mobile load times. Mobile optimisation requires: serving appropriately sized images for each screen width (using srcset), using modern formats (WebP, AVIF), lazy loading images below the fold and avoiding layout shifts caused by images loading without defined dimensions.
