Mobile-First Website Design: What Every Business Owner Should Know

Let’s do a quick test first.

Pull out your phone and visit a few business websites belonging to your industry.

You’ll notice some are very intuitive and effortless to use, while others require you to fight the whole way. 

Why does this happen? It mainly comes down to whether the site was designed mobile-first or for desktop. 

Mobile-first website design is now a must since Google ranking sites based on their mobile version. 

We created this guide to help you understand all aspects of mobile-first design for your website. You’ll learn how this approach affects user behavior, your conversions rates and search rankings, and what you can do to improve your site right away.

What the Term “Mobile-First” Means for Website Design

The first thing to know is that “responsive design” and “mobile-first design” aren’t the same thing. So many people use them interchangeably that we need to clear this up first. 

Responsive design means your website adapts its layout to fit different screen sizes. 

That sounds good, but the design process starts with a desktop design and then shrinks it down to fit a phone screen. 

The problem is that the mobile version looks like a compressed, scaled-down version of something built for a bigger screen. You can’t really call that “mobile-friendly”. 

On the other hand, mobile-first design works the other way around. 

You design for the smallest screen first and then expand outward to the tablet and desktop versions. 

What’s the benefit here? 

Since space is tight, you’re forced to prioritize. As a result, the mobile experience feels natural rather than squeezed, while the desktop experience looks cleaner. 

Here’s another way to think about it: in responsive design, you ask “how do we fit the website design on a phone?” But in mobile-first design, you ask “what does this need to be on a phone?”

Why Mobile-First Is So Important Now

With a poor mobile experience, you risk disappointing your audience while lowering your search visibility at the same time. 

Here are the reasons you should ensure a mobile-first design for your website: 

Mobile Users Are the Majority

Around 60% of web traffic is now mobile users. In South Asia, that number is even higher. 

And for many local businesses, especially services that people search for on the go, that number is closer to 70 or 80%. 

Google Ranks by Mobile

Did you know Google uses mobile-first indexing? That means Google’s bots look at the mobile version of your website to decide your rankings. So, a broken mobile experience is bound to hurt your visibility everywhere online. 

Mobile Intent Is Usually Urgent

By that, I mean someone searching on a phone is usually ready to act now find a restaurant, book an appointment, or request an Uber ride. You don’t want to lose these highest-intent visitors because they directly impact your sales. 

Patience Is Shorter on Mobile

We’re so used to endlessly scrolling on our phones that our attention spans have shrunk. You can be sure your mobile users won’t bother to leave your site immediately if they have too many frictions on the user journey. 

Common Mobile UX Mistakes 

This is important for you to know because if you’re not happy with your mobile experience, you might be making one or more of these mistakes: 

Too Small Text Size to Read 

There’s already friction if the visitor has to zoom in to read your content. Remember, the body text should be at least 16 pixels so it’s comfortable to read on a phone without having to pinch. 

Too Small or Too Close Tap Targets 

Fingers are not mouse pointers. Tiny buttons and links cause mis-taps and then frustration. 

Keep your tap targets at least 44 pixels tall with enough spacing that a thumb can hit the right one without zooming. 

Important Content Hidden Below the Fold 

What the visitor sees first is always precious, especially on a small screen. So, you should lead with what matters. 

We’ve seen many clients have a high bounce rate because their primary message and the main CTA require scrolling past a big hero image. 

Pop-Ups Covering the Whole Screen 

Users usually find pop-ups annoying. Now, think about a mobile pop-up that covers the whole screen with a close button too small to tap!

Guess what? Google also penalizes intrusive mobile interstitials.

We recommend that you save pop-ups for moments when the visitor has shown some interest in your product or service. 

Painful Forms to Fill Out 

Filling out a form on a phone is usually harder than on a desktop. Stay away from long forms, fields that don’t trigger the right keyboard, and tiny input boxes at all costs. 

Horizontal Scrolling & Broken Layouts 

One of the worst mobile experiences you can give is having to scroll sideways to see content, or elements that overlap and break. These are the obvious hallmarks of a desktop design forced onto a screen it was never meant for. 

What Makes a Great Mobile-First Design 

Now, let’s talk about the best practices for mobile-first design. If you’re redesigning your website or building it from scratch, try to incorporate all of them for a remarkable user experience. 

Design for the Thumb 

We usually hold our smartphones in one hand and tap with our thumbs. That means the easiest area to reach is the bottom and center of the screen. 

So, place the primary actions where our thumbs naturally land. You’ll get better results if you place a sticky button at the bottom compared to one stuck at the top. 

Prioritize Ruthlessly 

As said before, small screens force you to make hard choices. Decide what the single most important thing on every screen is and only then design around it.

The rule is simple: what doesn’t earn its place gets cut or pushed down, which helps make your web design powerful. 

Make Loading Speed a Priority 

Nobody tolerates a slow loading site today. Some of the ways to ensure a top speed is using compressed images, minimized scripts, browser caching, content delivery networks (CDNs), efficient code, and a good hosting service.  

Keep the Navigation Simple 

The hamburger menu hides your navigation behind a tap. It’s okay for secondary links but risky for your most important ones. Consider keeping your single most important action visible at all times.

Use Real Devices to Test 

Try to complete the main task one-handed while you’re a little distracted (the way real visitors do). The problems might become obvious fast when you test the way people browse in real-life scenarios. 

How to Know if Your Web Design Needs an Upgrade

Yes, there’s no place for guesswork in business. These quick checks will help you better understand your current situation: 

• Compare your mobile and desktop conversion rates in Google analytics. If your mobile performance is only half as good as your desktop performance, your mobile UX needs immediate attention for sure. 
• Run your site through Google’s PageSpeed Insights on mobile. 
• Look at your mobile bounce rate. If it’s much higher than desktop users, there might be friction in the design. 
• Watch your mobile session recordings as well. You will see exactly where people’s thumbs miss, where they zoom, and where they give up. 
• Find someone unfamiliar with your site and ask them to complete your main action on their phone. Take note of where and how they struggle. 

If these checks reveal a struggling mobile experience, some patch work won’t do any good. You need to invest in website redesign services to get the desired ROI. 

Mobile-First Website Design Is Just Good Business 

As you can see, mobile-first website design isn’t about chasing a trend. If you can nail it, your site will work for everyone. 

It’s obvious, if your site succeeds under the tight constraints of a small screen, it’ll work beautifully when there’s more room.
