Depending on how much you are connected with the web world, you may have heard the terms “responsive design” and “mobile-friendly.” You may have also heard that a major algorithm update is coming to Google on April 21, 2015 that may affect your online presence.

It boils down to this: sites that are not mobile-friendly will perform worse in mobile search rankings than their mobile-friendly counterparts. That means you may miss out on web traffic – or worse, leads – from potential customers or clients.

So why is Google putting so much emphasis on mobile? Because the amount of people using smartphones and tablets to access the internet now surpasses desktop computers. In fact, 60 percent of digital media time in the U.S. is now spent on mobile devices!

While there are several ways to make your website mobile-friendly, responsive design is Google’s preferred configuration. Responsive websites are optimized for viewing across various platforms, including smartphones and tablets.

You can also check if your website is responsive by adjusting the size of the web browser window on your desktop. Does the layout of the website change as you make the screen smaller? If so, you’re safe. Congrats! If you lose sight of the content as you shrink your window, then it’s probably time to redo your website.
