Responsive design with fluid grids, tap targets at least 44×44px, font size at least 16px, no horizontal scroll, and test on actual phones — not just Chrome's mobile emulator.
Mobile-first is not optional in 2026: 60–70% of traffic to small business sites comes from phones, and Google indexes the mobile version of your site as the primary version (mobile-first indexing has been universal since 2023).
**The technical baseline:** - Single-column responsive layout that reflows below 768px - Tap targets minimum 44×44px (Apple's HIG standard) with at least 8px between adjacent targets - Body text minimum 16px (any smaller and iOS auto-zooms on form focus, breaking your layout) - No horizontal scroll — ever, on any breakpoint - Form inputs use the right keyboard via input type (type="tel", type="email", inputmode="numeric") - Click-to-call links on every page (tel: links wrapping all phone numbers) - Fixed bottom CTA bar on long pages — significantly improves mobile conversion
**The performance baseline (because mobile = slow networks + slow phones):** - Total page weight under 1.5MB ideally, 2MB max - Hero image under 200KB, served as WebP or AVIF - No more than 3 third-party scripts - Defer non-critical JavaScript
**Test on real devices, not Chrome's device toolbar.** Borrow a 4-year-old Android phone from someone — that's your real user. The Chrome emulator shows you the layout but not the performance reality.
**Common mobile failures:** hover-only navigation menus (mobile has no hover), modals that can't be dismissed, "click to load more" buttons that don't work with swipe, and 200KB+ JavaScript chat widgets that block interaction for 3+ seconds.
- **How much does a small business website cost in 2026?** — $1,500–$15,000 for most small businesses, depending on whether you go DIY, freelancer, or agency. - **Should I use WordPress, Webflow, or Shopify for my business website?** — Shopify if you sell products. Webflow if design matters most and you want a working CMS. WordPress if you need maximum flexibility or already have a team that knows it. - **What is Core Web Vitals and how do I fix it?** — Three Google performance metrics — LCP (load speed), INP (interactivity), and CLS (visual stability) — that affect your search rankings. - **How fast should my website load?** — Under 2.5 seconds for the main content (LCP) on mobile 4G. Anything slower and you lose roughly 7% of conversions for every additional second.
