In case you hadn’t noticed, mobile traffic has officially overtaken desktop traffic. The shift to mobile-first design has become even more critical as people rely more heavily on their smartphones and other mobile devices to access the internet. Mobile has become the new normal, and it’s essential to have a mobile presence that delivers a seamless user experience (UX) to your customers. Long gone are the days when just having a website or app was enough. Considering 60% of all verified web traffic comes from mobile devices, it’s no wonder the current standard focuses on optimizing for mobile UX. If you want to remain relevant and competitive, prioritize mobile design. But designing for mobile first is more than just creating a mobile-friendly interface. It’s about understanding your customers’ needs and preferences and delivering a UX that caters to them. Form follows function in the design process by focusing on fast load times, easy navigation, and clear calls to action.

Designing for mobile first is not just an option; it’s crucial if you want the best traffic. It’ll most likely be essential if you want traffic at all in the future. It’s the critical first step in building a successful UX that delivers what your customers want and need. So, whether you’re a small business owner or a large corporation, now is the time to embrace mobile-first design.

Designing for mobile first is the critical first step to building a successful UX.

Designing for a mobile-first experience means that a business prioritizes a user-friendly mobile experience as the initial step in the design process. This approach ensures that a business’s website operates best for mobile devices like smartphones and tablets. As of April 2023, 82% of the US population owns a smartphone. It’s an understatement to say it might be important for businesses to create a seamless and enjoyable mobile user experience. One of the advantages of designing for a mobile-first experience is driving more traffic to a business’s website. Building a mobile-friendly website can attract more customers who prefer browsing the internet on their smartphones or tablets. Reasonably, this results in increased website engagement, more leads generated, and, ultimately, more revenue for the business. Creating a mobile-friendly website is about more than just creating a different version of the website for mobile devices. It’s about ensuring mobile experiences are as smooth and enjoyable as the desktop experience. The website’s design should be easy to read, with clear and concise information. People should be able to navigate the website seamlessly, regardless of their device. Creating responsive designs that adapt to different screens has become much easier with the materials and elements available today.

Best practices for a responsive, mobile-first design

Let’s explore some key principles of mobile-first design and get you some tips for optimizing your website for mobile.

The Differences Between Mobile-First Indexing and Design

Before we dive into the principles of mobile-first design, it’s vital to understand the difference between mobile-first web design and mobile-first indexing. While these two concepts are interconnected, they are not the same thing. Mobile-first web design involves designing a website for the smallest screen size and working your way up. On the other hand, mobile-first indexing is Google’s methodology of indexing websites based on their mobile-friendliness. While a mobile-friendly design does usually result in a better mobile-first indexing score, recognize that these are separate concepts.

Mobile First vs. Responsive Design

Another important distinction to make is between a mobile-first website and a responsive site. While many people use these terms interchangeably, there is a difference. Mobile-First. A mobile-first site is always responsive, but it prioritizes the mobile experience above all else. On the other hand, responsiveness refers to a design tactic that makes the site dimensions automatically adjust based on the user’s screen size, so for the moment, Responsive design is just that.

Ordering of Content on the Page

One of the most critical steps toward a better user experience is the visual hierarchy of content. Ensure headers, subheaders, paragraph text, call-to-action buttons, and sign-up forms lead visitors down the page and towards a desired action. When designing for mobile, be sure that main titles and featured images appear above the fold (the area of the screen a visitor sees before scrolling). Break up long chunks of paragraph text whenever possible to improve the quality of content and make it easier to read.

Sizing of Typography

Typography is another requisite consideration when designing for mobile. The text should be big enough to see but not so large that it becomes cluttered. The “line-height” metric is a designer’s best friend, allowing you to increase the spacing between lines of text while keeping the font size large enough to read.

Obvious CTAs

Call-to-action buttons are crucial for converting prospective customers into paid customers. To ensure that CTAs are eye-catching and attractive, use bold and saturated colors that contrast as much with each other as they do with your site’s main theme.

Loading Speed

Speed is essential when it comes to mobile web design. Ideally, it should take less than four seconds from the moment someone enters your domain to when the page is fully loaded. A slow website will lead to a higher bounce rate and a rankings demotion for lousy performance.

When in Doubt, Simplify

The takeaway for thinking mobile first is simplicity. Avoid cluttering pages with excess images, text, and other elements that could be distracting on mobile and hinder your load times. Consider reducing the number of pages on your website, focusing on hyper-targeted pages rather than a more extensive collection.

Where to start? A checklist for mobile-first strategy.

Mobile-first principles are critical for creating a great user experience. It’s an indispensable advantage for a site to perform well regardless of the device’s screen. The following are some best practices for mobile-first:

  1. Design for the smallest screen size and work your way up in size through your media query breakpoints.
  2. Optimize for mobile by considering the visual hierarchy of content, the sizing of typography, obvious CTAs, loading speed, and simplicity.
  3. Ensure that main titles appear above the fold and that the featured image is visible.
  4. Break up long paragraph text chunks to clarify the content and improve its quality.
  5. Use the “line-height” metric to increase the spacing between lines of text while keeping the font size large enough to read.
  6. Make the CTAs bright and bold using contrast and color.
  7. Ensure your website loads quickly and takes less than four seconds for the page to load.
  8. Declutter your pages by reducing the links in your navigation menu, providing only the most relevant pages for users to access.
  9. Give your website an app-like feel. Use a similar UI to apps, and keep the structure and visibility principles in mind.

By following these principles, you can create a seamless user experience for all screens and get the traffic your content deserves.

So, What’s the future of web design look like, and how can you get ready for it?

I don’t have a crystal ball. Much as I’d like to say I can predict what’s next, I can only provide an educated opinion. That said, here’s my take on what the future holds. Businesses will continue to adapt or die, especially if they keep up with where people spend their time online. As the responsive and mobile web slowly becomes the immersive web, a user interface will be a feature of devices and appliances that have never had one before. The first few generations of smart devices create unique challenges for developers. Mobile first principles and responsive design establish a foundation for how we rise to the opportunity to compete. I’d urge you to watch for trends in these specific areas:


Minimalist web design

As virtual and augmented reality trends become relevant in the marketplace, elegant visual representation of data that works with those immersive environments will become more enticing and compelling. Look for UX trends to include a reduction of lengthy text or numerous buttons or links.

Voice control

The rise of a new generation of Artificial Intelligence is producing autonomous agents surfing the web all by themselves. Interfaces without a screen are already pretty popular for the home. We will be talking and listening to devices more in the near future.


Smart Watches, AR glasses, VR rigs, and headsets are already usable and ubiquitous depending on what activities you enjoy or what kind of work you do. These devices will continue to evolve as our technology needs change, and it’s anybody’s guess what directions they will evolve in. Of course, the areas of innovation aren’t limited to these. They will come from niches that spark the most interest and activity through novelty and utility alike. No matter how our personal technology evolves, our design choices should always lean toward accessibility over aesthetics. We will continue to have the anchors of metadata and content needing a container. What that container is, how it appears to the consumer, and how it integrates into the business process are the metrics of every significant design challenge in content delivery since the days of newspapers and radio. We will endure, but somewhere around 20% of us will adapt, and a rough 10% of those folks will thrive; those with a creative spirit and a desire to meet the everyday user’s needs.

Conclusion: Whether Android or iOS, mobile-first design isn’t going away.

More people are accessing the internet through their mobile devices than any other way, period. This makes it absolutely necessary for businesses to prioritize mobile devices and content to ensure that their websites are accessible and easy to use for all users, regardless of the device they are using. By adopting a mobile-first approach, businesses can enhance the user experience and improve their website’s visibility on search engines. Google has made it clear that mobile responsiveness is a significant factor in their search ranking algorithm, making it more fundamental to ensure that your website is mobile-friendly. To sum up, a mobile-first approach to design and content is essential for businesses that want to catch up to the curve and deliver an accessible user experience to their customers. By prioritizing mobile screens during the design process, anybody can create a great-looking website that works well on any device, improving engagement, conversions, and, ultimately, customer satisfaction and loyalty.
