UX
Over 60% of web traffic is mobile, and Google uses mobile-first indexing — meaning your mobile site determines your rankings. Yet most websites are still designed desktop-first and adapted for mobile as an afterthought. This checklist covers the specific mobile issues that hurt your SEO, conversions, and user experience.
Audit my mobile siteGoogle's mobile-first indexing means the mobile version of your site is what Google uses to index and rank your pages. If your mobile site has less content, broken layouts, or missing structured data compared to your desktop site, you're losing rankings. Mobile-first isn't a design preference — it's the default way the web is consumed and indexed.
Buttons and links that are too small or too close together are frustrating on mobile — users tap the wrong thing or can't tap at all. Google recommends a minimum 48x48 pixel tap target with at least 8 pixels of spacing between targets. Check your navigation menu, your CTA buttons, your form submit buttons, and any icon links. If they're smaller than 48px, they're failing on most mobile devices.
Text that's readable on a 27-inch monitor isn't necessarily readable on a 5-inch phone. Check: is your body text at least 16px on mobile? Is your line height at least 1.5? Do your headings scale down appropriately? Is there enough contrast between text and background? Long paragraphs that look fine on desktop become walls of text on mobile — break them up.
Is your mobile site costing you rankings and conversions?

Mobile users are on slower networks and less powerful devices. A page that loads in 2 seconds on desktop fibre might take 6 seconds on mobile 4G. Google's Core Web Vitals thresholds are stricter for mobile. Compress images, defer JavaScript, use a CDN, and minimise redirects. Velrix's audit shows your real mobile Lighthouse score and the specific resources slowing your mobile site down.
Nothing frustrates mobile users more than content jumping around as the page loads — they tap the wrong button because the layout shifted at the last moment. This is measured by Cumulative Layout Shift (CLS), one of Google's Core Web Vitals. Common causes: images without dimensions, ads without reserved space, fonts that load late and push text, and dynamically injected content above the fold. Set dimensions on every visual element.
Desktop navigation menus don't work on mobile — they're too wide, too small, and require hover states that don't exist on touch screens. Your mobile navigation should be a hamburger menu that's easy to reach (bottom-right for right-handed users), opens quickly, and shows the most important links first. Don't bury your main pages 3 levels deep in a mobile menu.
Mobile forms need to be simpler than desktop forms. Each additional field is more friction on a small screen with a touch keyboard. Use the correct input types (email, tel, number) so the right keyboard appears. Use autofill where possible. Make form fields large enough to tap easily. Show clear error messages inline — don't make users scroll up to find what went wrong.
If you're still designing for desktop and adapting for mobile, you're building for the minority of your visitors. Velrix's audit engine checks your mobile site specifically — mobile page speed, mobile readability, tap targets, and mobile-specific conversion issues.
