Frequently Asked Questions
What is responsive web design?
One website that adapts to any screen using fluid layouts, flexible media, and media queries. We design mobile‑first, then progressively enhance. You get lower maintenance, consistent UX, stronger SEO (single URLs), and better conversions on phones.
How will this improve mobile conversions?
We remove friction: readable type, clear hierarchy, good spacing, fast media, and simplified forms. CTAs match mobile behaviour (click‑to‑call, WhatsApp, maps). Typical gains: 20–120% lift within weeks.
Does this help SEO?
Yes. Google indexes your mobile experience first. Responsive sites consolidate URLs, improve Core Web Vitals, and keep structured data consistent. Faster pages and better engagement drive visibility and revenue.
What performance targets do you hit?
Sub‑2‑second mobile render on 4G and green Core Web Vitals. We use critical CSS, responsive images (AVIF/WebP), caching, preconnect, script hygiene, and code splitting. You’ll see Lighthouse and field (CrUX) proof.
How do you ensure accessibility (WCAG 2.1 AA)?
Contrast, keyboard navigation, visible focus, semantic landmarks, alt text, labels, helpful errors. Tested with VoiceOver/TalkBack, light/dark, and at 400% zoom. You get an audit and compliance checklist.
Can you retrofit my existing site?
Often yes. We start with a responsive audit, then ship high‑impact fixes (viewport, fluid type, responsive images, spacing/tap targets, navigation). If technical debt is heavy, we suggest a phased rebuild.
How long does it take?
Landing page: 2–4 weeks. Corporate: 6–10 weeks. E‑commerce/PWA: 10–16+ weeks depending on integrations. We deliver a high‑impact MVP early, then iterate.
How do you test across devices?
Physical lab (iPhone/Android generations, tablets, foldables, TV) + BrowserStack + automation. We test orientation, low bandwidth, glare, and accessibility settings to reflect real UK use.
What about ongoing maintenance?
We monitor performance (Lighthouse/CrUX), fix issues, and update components. Optional plans include A/B testing, new templates, device updates, and accessibility reviews.
How do we start?
We’ll audit your current mobile experience, quantify lost conversions, and propose a plan with milestones, pricing, and performance guarantees. Then we move quickly on the highest‑impact pages.
