Mobile-first design means starting the design and development process with the smallest screen — typically a 375px smartphone — and progressively enhancing the layout for larger screens. This approach is superior because: it forces ruthless prioritization of content and features that matter most, it aligns with how Google indexes and evaluates your site, it results in leaner CSS code, and it ensures the experience is excellent on the device most of your visitors actually use. Traditional “desktop-first then shrink” approaches produce cramped, compromised mobile experiences.

We test across a comprehensive matrix of real devices and browsers. On mobile: iPhone SE, iPhone 14 Pro, Samsung Galaxy S23, Google Pixel 7, and various mid-range Android devices — on Safari, Chrome for iOS, Chrome for Android, Firefox for Android, and Samsung Internet. On tablet: iPad Air, iPad Pro, and Samsung Galaxy Tab. On desktop: Chrome, Firefox, Safari, Edge, and Opera at 1280px, 1440px, and 1920px. For Enterprise packages, we extend to 30+ combinations including older device simulation for maximum compatibility.

We do both. If you already have a desktop website that isn’t mobile-friendly, we can retrofit responsive design into your existing codebase — rewriting the CSS architecture, implementing media queries, refactoring layouts, and adding mobile-specific UX improvements without rebuilding the entire site. This is typically faster and more cost-effective than a full rebuild. We’ll audit your existing site first and provide a specific quote for the retrofit work required based on its complexity.

We deliver clean, standards-compliant HTML5, CSS3, and JavaScript files that can be integrated into any platform or CMS — including WordPress, Webflow, Shopify, or a custom backend. If you’re on WordPress, we can convert the responsive design into a custom theme. For Webflow projects, we design and build directly in Webflow. All source files, assets, fonts, and documentation are included. We also provide a handover call walking you through the codebase and how to make basic content updates yourself.

Yes — directly and measurably. Google has used mobile-first indexing since 2024, meaning your mobile site’s performance determines your search rankings across all devices. A mobile-unfriendly site receives a “Not mobile-friendly” signal that actively suppresses rankings. Beyond the binary pass/fail, Core Web Vitals scores (which our designs are engineered to pass) are confirmed ranking signals — better LCP, CLS, and FID scores correlate with higher positions. Our clients typically see measurable organic ranking improvements within 4–8 weeks of launching a properly optimized responsive design.

Revision rounds depend on your package: Starter includes 2 rounds, Professional includes 5, and Enterprise includes unlimited revisions. Each revision round involves you reviewing the current design, consolidating all feedback into one document, and us implementing all changes in a single round. We use Figma or a staging URL for design review, making it easy to leave precise comments on specific elements. We’ve found 2–3 focused revision rounds are sufficient for most projects when clients provide consolidated, clear feedback.
