Following are some prominent reasons why you should have responsive design for your website:
Flexible: Sites with responsive design are very flexible. The content, images and even videos, loaded in a site can easily adjust to small screens of mobiles and tablets. The images and the grids of such sites are fluid.
Audience Reach: According to a survey, 40% of online users prefer to browse sites on their tablets or mobiles. It means if your site is not mobile friendly, you are losing a percentage of audience. Reach them by having responsive web design. It enhances the site traffic rate by increasing its visibility.
Terrific Offline Browsing Experience: There is no cut in the screen size. It means all content is visible. The HTML5 offline browsing capability of responsive sites allows easy access with a single click.
No additional Mobile site: It saves your money that you might plan to spend on creating an additional mobile friendly website. It is an old trend to own two types of websites, one for system browsing and another for mobile browsing. Your one site is enough to operate on both the platforms, which is a great saving of money as well as time.
Effective SEO Campaign: Maintaining a mobile friendly site and a desktop friendly site, means duplicate content, which is a crime as per Google. Having one responsive site doesn't promote duplicate content. You can make your SEO campaign successful and effective with it.
