If you’re still making websites for desktop first and neglecting the mobile end, fix yourself. The year is 2025, mobile-first isn’t a trend, it is the foundation of good web design, SEO strategy, and user experience. Over 60% of your web traffic is coming from mobile devices now. Your website’s performance NEEDS to work on mobile devices. Don’t let people perceive your brand to be slow and sloppy because of your desktop website. Let’s take a look at the facts:

Why Mobile-First Matters Now More Than Ever

If your mobile experience is broken or missing key content, your visibility in search engines will suffer. Now not only are you showing up less on Google, but if a customer does click on your website, they’re going to struggle with your interface.

In less than a second they have decided that your brand is not one they want to do business with. In 2025, you need to have a responsive web design. Imagine giving your competitors customers just because your website isn’t up to date. Users expect fast, intuitive, and touch-friendly experiences. This is so important when a user clicks on your ad and it links to your site.

If your website is taking more than 2 seconds to load, they will leave, likely never to return. The bottom line is, to a customer your website is a reflection of your company.

What Does Mobile First Look like?

One of the biggest misconceptions about mobile-first designs is that you are just shrinking your content to fit on a smaller screen. The reality is you need to focus on what matters most. You need to streamline the user’s journey to where they need to go and optimize performance. Here are some of the factors when making a mobile-first design: speed, legibility, touch-friendly, one goal per screen, and scaling.
