Picture this: A potential customer is scrolling through their phone while waiting for coffee, searching for a local business just like yours. In a matter of seconds, they'll decide whether to explore your website or move on to a competitor. But, your website is taking too long to load. Or there’s a pop-up that gets in the way of their intended action.
Your customer exits your website.
Today, more than 60 percent of web traffic comes from mobile devices. And in 2023, mobile retail sales in the U.S. alone exceeded $491 billion. That figure is expected to grow almost two-fold by 2027. Having a mobile-first website is essential for business survival, even if you’re not an e-commerce site. Whether you’re designing your first site or updating your existing digital home, here’s how to make sure you’ve optimized for the way today’s customers browse.
Start with a mobile-first design
It used to be that websites were built for desktop computers and then scaled down for mobile devices. No more. Today's successful businesses take a mobile-first approach, designing for smartphones first and then scaling up for larger screens. This strategy ensures your core content and functionality work seamlessly where most of your customers are visiting you from—their phones.
Why mobile-first? Think of the approach like building a house from the foundation up, rather than trying to shrink a mansion into a tiny home. It’s much easier to build small and expand than build large and try to make things look good on a much smaller screen, where every interaction must be intuitive.
The essential elements of mobile optimization
So you’re convinced that mobile-first is the way to go. Great! Here are a few other things to keep in mind.
Speed matters
Mobile users are notoriously impatient. According to one study, more than 40 percent of mobile visitors will abandon a site that takes longer than three seconds to load. One Mississippi…two Mississippi…three Mississippi…
To keep your site running at peak performance and avoid a high bounce rate:
- Compress images to have your site look good without sacrificing quality
- Minimize code and remove unnecessary scripts
- Enable browser caching so your site loads even more quickly for repeat visitors
- Consider using accelerated mobile pages, or AMP, for critical content
Consider size and spacing
Remember, your users are navigating with their fingers, not a precise mouse cursor. Minimize frustration by designing with touch in mind:
- Make buttons and links at least 44x44 pixels so they’re easy to click
- Space clickable elements far enough apart to prevent accidental clicks
- Use larger font sizes (minimum 16px for body text)
- Ensure any forms or input fields are easy to tap and fill out
Make it easy to navigate
Without the luxury of a large screen, navigation needs to be simple and intuitive for mobile visitors. Consider implementing:
- A clear, compact menu, like a hamburger menu
- A prominent search function
- A sticky header with essential elements
- A simple path back to your homepage
- Easy access to contact information and key site areas, like FAQs or About Us sections
Creating content that works on smaller screens
Viewing big blocks of text is a surefire way to drive people away from your site. Content needs to be concise and scannable on mobile devices:
- Use short paragraphs of 2-3 sentences at a time
- Incorporate clear headings and subheadings
- Place crucial information at the top of blog posts or include a table of contents so people can easily click to relevant information
- Use bullet points and white space effectively
- Ensure images scale properly and maintain their meaning on small screens
What about pop-ups?
Ahh, the ubiquitous pop-up. While they can be effective for desktop users to drive actions like filling out a form or asking a question, pop-ups often create frustration on mobile devices. If you must use them:
- Make them easy to dismiss
- Ensure they don't cover the entire screen
- Delay them until users have engaged with your content
- Consider using bottom banners instead
- Make sure they're truly mobile-responsive
Forget set and forget
Your mobile website isn't a set and forget project. In fact, you’ll want to have ongoing testing and optimization to ensure it’s performing as best it can or to make tweaks based on visitor behavior. To help do this:
- Use a mobile-friendly test tool to see how your site performs
- Test on various devices and browsers; what works on one may not work on all
- Monitor mobile-specific analytics
- Gather feedback periodically from your visitors
- Conduct regular speed testing and optimization, particularly after any major website updates
Your website is often the first—and most frequent—way customers interact with your business. As mobile technology evolves, your site needs to be flexible enough to adapt to new devices, screen sizes, and user expectations. Small businesses that embrace mobile-first design create experiences that make it easy for customers to connect and convert, whether they're shopping online or heading to a physical location. And isn’t that what it’s all about?
