Yes, it's important to optimize your website for mobile browsing. With the increasing use of smartphones and other mobile devices, a large number of people are accessing websites on the go.
A mobile-optimized website adjusts to small mobile screens and makes it easy for users to browse without any problems. This can include features such as a responsive design, larger text and buttons, and streamlined navigation.
Search engines like Google use mobile-friendliness to rank websites, so those not optimized for mobile may not rank high.
