More than 60% of all web traffic comes from mobile devices — and for local businesses, it's even higher. If your website isn't mobile responsive, you're losing customers every single day without realizing it.
But what does "mobile-friendly" actually mean? It's more than just fitting on a small screen. Use this mobile-friendly website checklist to audit your own site and find out if you're really ready for mobile visitors.
Layout & Design
- Responsive design that adapts to any screen sizeYour site should look great on a 4-inch phone and a 13-inch tablet. No horizontal scrolling, no cut-off content, no overlapping elements. Test on at least 3 different screen sizes.
- Text is readable without zoomingBody text should be at least 16px on mobile. If visitors have to pinch-to-zoom to read your content, they'll leave. Headings should scale down proportionally.
- Buttons and links are tap-friendlyTouch targets should be at least 44×44 pixels with enough space between them. Fat fingers on tiny links = frustrated customers. Make buttons big, obvious, and spaced out.
- No horizontal scrollingEvery element should stay within the viewport width. Images, tables, and embedded content are common culprits. If anything causes side-scroll, fix it.
Speed & Performance
- Page loads in under 3 seconds on mobileTest with Google PageSpeed Insights on a mobile connection. Compress images, minify code, and use modern formats like WebP. Every second matters.
- Images are optimized and properly sizedDon't load a 4000×3000 image and scale it down with CSS. Serve appropriately sized images. Use lazy loading for images below the fold.
- No render-blocking resourcesLarge CSS and JavaScript files that block rendering make your site feel slow even if it loads quickly. Inline critical CSS and defer non-essential scripts.
- Minimal use of large libraries and frameworksjQuery, Bootstrap, and other frameworks add weight. If you're only using 5% of a library, you're making every visitor download the other 95% for nothing.
Navigation & Usability
- Mobile navigation is easy to useA hamburger menu or simplified nav that works with one thumb. No mega-menus that require precision tapping. The most important pages should be reachable in one tap.
- Phone number is clickableWhen someone finds your business on their phone, they should be able to tap your number and call immediately. Use
tel:links. This alone can double your mobile calls. - Forms are mobile-optimizedUse appropriate input types (email, tel, url) so the right keyboard appears. Keep forms short — every field you remove increases completion rates.
- No pop-ups that block the screenGoogle penalizes intrusive interstitials on mobile. Full-screen pop-ups that are hard to close will tank both your rankings and your conversion rate.
Content & SEO
- Viewport meta tag is set correctlyYour HTML must include
<meta name="viewport" content="width=device-width, initial-scale=1.0">. Without it, mobile browsers render the desktop version. - Content is scannableShort paragraphs, clear headings, bullet points. Mobile readers scan — they don't read long blocks of text. Break it up.
- CTA is visible without scrollingYour primary call-to-action should be above the fold on mobile. "Call Now," "Book Online," or "Get a Quote" — whatever your conversion action is, make it unmissable.
- Google Mobile-Friendly Test passesRun your URL through Google's Mobile-Friendly Test. If it doesn't pass, Google is penalizing your rankings. Fix whatever it flags.
