You probably know by now that mobile has taken off, and there’s no stopping it anytime soon. What you probably didn’t know is just how popular mobile really is. In fact, did you know that the number of mobile users has already overtaken the number of traditional, desktop users? It’s true! According to comScore, an Internet analytics company, this past March saw, for the first time ever, the number of mobile-only users surpassing desktop-only users, at least in the US. Let me put it another way: there are now more people accessing the web on their mobile phones than there are people doing it from the comfort of their homes, on their desktops. This has humongous implications for mobile UX design. Huge! This means that people are increasingly buying things or reading the news on their mobile phones while on the go. The failure to design with mobile in mind will be catastrophic for any e-commerce site or publication.

Keep your design minimalist

Keep your mobile design clean and simple. Go for practicality and usefulness over any fanciness in your design. Remember that you’re designing for a much smaller screen than if you would for desktop. With screen real estate being very precious, it’s also just common sense that you can’t do a complex design. Thus, minimalism is your best bet. This also helps the user experience. After all, when users are looking at an uncluttered interface in their iPhones or Android devices, they’re going to be able to find what they’re looking for on a site extremely quickly, which improves their user experience. What does minimalism on a mobile screen look like? Users should only see the content that they need to see to properly use the site—which will automatically prompt them to explore and navigate further. Also, buttons and menus should be intuitive, in keeping with the focus on simplicity. Look at Crate & Barrel’s mobile site. It’s a study in mobile minimalism because its hamburger menu is tucked away on the top-left of the screen, yet still noticeable, and you know immediately what site you’re on thanks to the word-mark logo on top. Also, the colors and fonts are both basic, which ensures users aren’t overwhelmed.

Be mindful of different devices and environments

Though you’re designing for mobile, not all mobile devices are created equally. This is key to successful mobile UX design today, but some designers forget that there are various platforms for which they have to design. Designing for mobile means designing for mobile apps and mobile sites. It’s imperative that you understand what devices your audience uses and what their mobile behavior is like. In other words, you shouldn’t design an app or a mobile site with the mistaken belief that iPhone and Android users will interact with your app or site in the same way. Research shows that iPhone users spend more on mobile ecommerce than do their Android counterparts. What’s particularly stunning about this stat is that there are fewer iPhone users than Android users, making iOS users’ spending power even more significant! Therefore, if you’re designing mobile apps and sites for an ecommerce business, you’ll want to focus first and more heavily on making a top-notch UX for iOS than you would for Android — simply because there’s more money to be made.

Use familiarity to create highly functional navigation

Though there are now more people surfing the Internet on mobile than desktop, many of those people obviously started out browsing websites on their desktops. This means that they’ve come to expect a certain standard in terms of site navigation and appearance from all their time using desktop. Therefore, when designing for mobile, don’t mess with expectations and conventions: make sure your client’s mobile site replicates the navigation standards of any desktop site with great UX. Here are some common features that you should carry over into your mobile navigation:

• Your most popular categories or site pages, based on analytics data
• Navigation menu in the form of a hamburger menu
• High-quality images
• Prominent search feature
• Clear, huge call-to-action buttons

We can see highly functional navigation on Lowe’s mobile site because it features all of the navigational conventions that we’re used to seeing on any good desktop site.

Make the checkout process as convenient as you possibly can

This is the most important tip on this page, by far. It’s so important that every other tip leading up to this is useless if you failed to design your client’s mobile site in such a way as to get the conversion at the end of the user’s mobile-site browsing. The last thing you want is that dreaded shopping cart abandonment to occur, especially when you’ve already gone through the trouble of recognizing and trying to design a completely mobile-friendly site. Unsurprisingly studies show that like on desktop, shopping cart abandonment occurs on mobile when the UX is bad. For a mobile shopper looking to buy something, the user experience is the worst it can be when they’re trying to place an order…so when something goes haywire, they get frustrated, and leave your site forever, never to come back, not even on the desktop! One of the most notorious ways that the mobile checkout process can suffer is when the call to action and checkout buttons fail to support the shopper’s expectations. For instance, the buttons could be too small to easily see or tap on, or they could just fail to appear as soon as items are added to the cart. For an inspiring example on doing this basic design feature right, we look to Cult Pens’ mobile product page for one of its Pental brand pens. Note the large “add to basket” button splashed across the entire bottom of the page.

Mobile design: different from desktop design

Some designers just don’t get it. Designing for mobile is an entirely different concept than designing for desktop. Sure, you’ll have similarities, but they only go so far. Of course you want to keep your mobile design as close to the conventions that users are used to from desktop browsing, but there are exceptions. Minimalism — doing more with less — should be the golden rule for mobile design since the screen’s much smaller. Designers also have to understand that the user behavior for iOS and Android isn’t the same, so it’s best to research what each user base does with their smartphones beforehand. Of course, you’ll also have to design different mobile and apps for different platforms. Finally, the big one to get right is to make the checkout process as smooth as possible. Never inhibit shoppers from buying on their smartphones! If you do, it’s like throwing money out the window. Follow all these mobile-design best practices, and you’ll have happier clients who’ll get more conversions. Images use mobile experience image via Shutterstock.
