Mobile conversion optimization: improving conversions on small screens

Home / Everything About / Everything About Analytics / Mobile conversion optimization: improving conversions on small screens

Your mobile conversion rate is one percent. Your desktop conversion rate is five percent. Mobile visitors see the same offer as desktop visitors. The same product. The same benefits. Same everything. But mobile converts at a fraction of desktop. The difference is not the offer. The difference is friction. Mobile has more friction. Screens are smaller. Typing is slower. Forms are awkward on touchscreens. Images take time to load over mobile networks. Checkout requires scrolling endlessly. Every step feels harder on mobile. This friction kills conversions. A visitor on desktop fills a form in two minutes. The same form on mobile takes seven minutes. By minute three they have abandoned. Mobile conversion optimization removes this friction. It simplifies forms. It speeds up pages. It redesigns for touch. It removes unnecessary steps. The goal is not to make mobile conversion equal to desktop. It is to remove the artificial friction that kills mobile conversions. This article explains mobile conversion optimization and how to improve conversions on small screens.

Why mobile conversions are lower

Mobile conversions are lower for legitimate reasons. Mobile users are distracted. They are in coffee shops and on trains. They are interrupted. Mobile devices are slower. Networks are slower. Devices have less processing power. Mobile experiences take more effort. Typing is harder. Scrolling is required. Tapping small targets is hard. These are real constraints. Mobile optimization cannot remove these constraints. But it can minimize their impact.

Form optimization for mobile

Forms are the biggest friction point on mobile. A ten-field form on desktop is manageable. On mobile it requires endless scrolling. Simplify forms for mobile. Reduce fields from ten to three. Ask for only essential information. Ask for optional information after conversion. Use auto-fill and pre-fill when possible. Let mobile browsers fill in email and address automatically. Use input types that bring up appropriate keyboards. A phone number field should bring up a number keyboard. An email field should bring up an email keyboard. These small changes reduce friction.

Speed optimization for mobile

Mobile networks are slower than desktop networks. Slow pages cause abandonment. Optimize images. Compress them. Serve appropriately sized images for mobile screens. Do not serve a four-megabyte desktop image to a mobile phone. Minify code. Remove unnecessary JavaScript. Defer loading non-critical JavaScript until after the page loads. Cache aggressively. Store static assets on the device so they do not need to be downloaded again. Test your page speed on mobile. Google PageSpeed Insights shows you what to fix.

Button and touch optimization

Buttons need to be larger on mobile. Fingers are less precise than mice. A button that is easy to click on desktop might be impossible on mobile. Make buttons at least forty-four by forty-four pixels. This is about the size of a human finger. Space buttons apart so they cannot be accidentally tapped. Do not put two buttons right next to each other. Remove hover effects. Hovering does not exist on mobile. Hover effects confuse mobile users. Replace them with active states that show what happens when you tap.

Checkout optimization for mobile

Checkout is where mobile abandonment is highest. Simplify checkout. One-page checkout is better than multi-page on mobile. Reduce form fields. Pre-fill what you know. Show progress clearly. Let users know how many steps remain. Offer guest checkout. Do not force account creation before purchase. Offer multiple payment methods. Some users have Apple Pay. Some have Google Pay. Some use credit cards. Supporting all reduces friction.

Testing mobile optimization

A/B test mobile changes. A simplified three-field form against a ten-field form. A larger button against a smaller button. A one-page checkout against a multi-page checkout. Measure which converts better. Implement what works. Mobile is different enough that changes that work on desktop might not work on mobile. Test on actual mobile devices. Testing in a browser on desktop is not the same as testing on a phone.
