Even in the past couple years, the desktop traffic continues to dip, & mobile continues to spike. Thanks to high speed mobile networks that have enabled people to search and gain any information in seconds.

According to CNBC, almost three-quarters (72.6 percent) of internet users will access the web solely via their smartphones by 2025, equivalent to nearly 3.7 billion people, making it absolutely crucial to optimize your website for responsive web design.

Earlier, we published an article which talks about the importance of mobile-first design in 2021 and how businesses are already taking progressive steps towards optimizing their mobile website experience. But what needs to be the focal point is having a clear responsive web design checklist in place in place to ensure a seamless user experience. A critical part of that experience is speed.

Do you know you’ll lose out a lot on traffic and sales if your site loads slowly? According to Google, even a 1-second delay in mobile load time can impact conversions up to 20%. Making it crucial for your business success, and in some cases survival, that your website loads faster on mobile.

When testing your mobile website speed, you have to keep in mind that monitoring your website performance on a high-speed internet connection will not provide you accurate results. Why? Because mobile is a different story – it’s not like a desktop on which people usually access the internet on a high-speed connection.

In fact, on mobiles, slow phone data and internet speed are common, especially when people are on the go. This makes it extremely important for you to monitor and test your websites on different network conditions to analyze your website performance. Testing on variable speeds helps you analyze and provide a good user experience on mobile. It will also help you improve your search engine rankings – as search engines prefer websites that load quickly.
