When a website is responsive, that means that it's designed in a way that responds, or adjusts, to whatever screen it is being viewed on. Designing a website to be responsive is a best practice to make sure your site is mobile-friendly. These days, with so many people searching and browsing on mobile devices, being responsive is important. It helps your customers have a better online experience with your firm. But beyond the experience, search engines like Google rank responsive websites higher in their search results than sites that aren't responsive.
