Rebuild for the 70% of visitors who never see desktop.
Mobile-first redesign with desktop as progressive enhancement. Thumb-zone forms, tight performance budgets, measurable conversion lift.
Who this is for
B2C or DTC founder whose site sees 70%+ mobile traffic but was designed desktop-first — mobile bounce over 65%, mobile conversion under 1%, and forms nobody can fill on a phone.
The pain today
- Bounce over 65% on mobile despite decent desktop numbers
- Forms designed for desktop that break on a phone keyboard
- Hero images 4–5 MB that never render before the scroll
- Navigation that requires zooming or both thumbs
- Design system built around desktop grid, never stress-tested on mobile
The outcome you get
- Mobile bounce cut substantially, mobile conversion lifted
- LCP under 2 seconds on 4G mobile networks
- Thumb-zone-safe forms, CTAs, and navigation
- Desktop experience that feels intentional, not like a scaled-down mobile
- Performance budgets and component guidelines the team can maintain
Mobile-first ≠ responsive — the real difference
Responsive design makes a desktop site survive on mobile. Mobile-first design treats mobile as the primary experience and enhances for desktop. In practice: you start with 375px viewport in Figma, not 1440px. You write the CSS smallest-first, not largest-first. You assume 4G network and mid-range Android, not fiber and a MacBook. Hero images are 100KB, not 4MB. Forms are thumb-reachable. Navigation fits in one hand. When you design this way, desktop gets the upgrade automatically — more space, more detail, more parallel content — and nothing breaks. The other direction (desktop-first, then shrunk) always produces mobile experiences that feel like compromises.
Touch targets, thumb zones, and form patterns
Apple's Human Interface Guidelines specify 44px minimum touch target. Material Design says 48dp. In practice I use 48–56px for primary CTAs. Thumb zones matter: the bottom third of the screen is easy reach, the top third is stretch, the upper corners are hard. Primary CTAs belong in the easy-reach zone, which is why mobile bottom navigation survived while hamburger menus are increasingly a penalty. For forms: one field per line, generous spacing, inputmode attribute so mobile keyboards show the right keys, no dropdowns where a native picker works better, no placeholder-as-label, and inline validation that appears on blur, not on every keystroke. Autofill-friendly name attributes cut completion time dramatically.
Performance budgets for mobile networks
A mobile visitor on a subway is on 3G or worse, half the time, globally. Budget accordingly. Total page weight under 300KB for the hero render. JavaScript under 100KB after compression. A single hero image under 100KB (AVIF or WebP with srcset). Web fonts: one family, two weights max, subset to Latin if your market allows. Third-party scripts deferred or server-side. I set these as budgets enforced in CI — the build fails if a PR pushes the bundle over threshold. This is the difference between a site that's fast on launch day and a site that's fast a year later when every team has added something.
Case study: LAK mobile-first manufacturing B2B
LAK Embalagens is a B2B manufacturer where buyers increasingly browse on mobile during on-site factory visits or between client meetings. The old site was desktop-first, huge product galleries, unreadable on a phone. I rebuilt mobile-first — thumb-friendly nav, compressed product galleries with lazy loading, quote-request form designed for a phone keyboard. Bounce rate dropped 45%. Search Console impressions tripled. Top 3 Google rankings in its categories. The win wasn't dramatic graphics — it was removing friction for the buyer who's holding a phone with one hand in a warehouse.
Pricing and warranty
Mobile-first redesigns fit the Websites Business or Redesign tier, starting at $4,000 for a focused rebuild and $5,000+ for larger sites. Typical timeline 3 weeks. 14-day money-back guarantee, 1-year bug warranty, Work Made for Hire. I also include a mobile QA checklist and real-device testing (not just Chrome DevTools simulation) — iPhone and Android, 4G network throttling, multiple screen sizes. If the site regresses after launch because a new team member shipped something, the warranty covers fixes for anything I originally built.
Desktop as progressive enhancement
A common fear with mobile-first is that desktop will look worse. The opposite happens when it's done right. Desktop layouts get space the mobile layout can't use — side-by-side content, hover states, larger imagery, multi-column navigation. The primary flows stay consistent (same CTAs, same form, same copy), but the layout takes advantage of the viewport. Container queries, introduced in 2023, make this especially clean — components respond to their own space, not the viewport — so a card can look different when it's 300px wide vs 800px wide without media query spaghetti. The result is a desktop experience that feels considered, not like a stretched mobile page.

Frequently asked questions
The questions prospects ask before they book.
- How do I know if my site actually needs a mobile-first redesign?
- Two signals: mobile traffic is over 50% of sessions, and mobile conversion is meaningfully lower than desktop (often 3–5x lower on a desktop-first site). If both are true, you're losing the majority of revenue opportunity. GA4 device breakdown tells you in 10 minutes.
- Will the desktop version look worse?
- Done right, no. Desktop gets more space — side-by-side content, hover interactions, larger imagery, multi-column nav. The flows stay consistent but the layout takes advantage of the viewport. If you have a current desktop design you love, I preserve its voice while making mobile primary.
- Do you test on real devices?
- Yes. Chrome DevTools simulation catches maybe 70% of mobile issues. The rest — touch latency, scroll jank, font rendering, tap target collisions, iOS-specific quirks like viewport issues with the keyboard — only show up on real devices. I test on iPhone and Android as part of every mobile engagement.
- What about native apps vs a mobile-first website?
- For most marketing sites and many commerce sites, a great mobile web experience outperforms a native app — no install friction, easier SEO, cheaper to maintain. I'll tell you honestly if a native app is actually the right call for your use case (usually repeat-use transactional apps) vs a mobile-first web rebuild.
- Can you also improve performance during the redesign?
- Yes, and usually I do it in the same pass. Mobile-first and performance share most of the same levers — smaller images, less JavaScript, faster server response. Redesigning mobile-first without fixing performance would waste half the work. Core Web Vitals pass is part of every mobile-first engagement.
