The use of mobile devices to surf the internet is growing at an rapid pace, but unfortunately many websites aren’t optimized for those devices. Mobile devices are limited by size and need a different layout for the website content.
Responsive web design changes the layout of a website according to the needs of the users and the devices they’re using. The layout is flexible based on the size and capabilities of the device. For example: with responsive web design users would see content shown in two or three columns on a laptop; whereas an iPhone might show the same content in one column.
A responsive website is much better than having a separate website for each mobile device because there is only one site to update as opposed to multiple sites. Also, having separate mobile websites will actually count as duplicate data. Google and other search engines may penalize you for this.
In January 2014, mobile devices accounted for 55% of Internet usage in the United States. The usage of PCs was at 45%. 55% of American adults had smartphones, while 42% owned tablets, according to the Pew Research Center.
So it is very important that your website is responsive. If your visitors can navigate through your pages with ease, they are more likely to become your clients!
