As smartphone and tablet use rapidly increase so does the importance of having a mobile-friendly website.
Because it is impossible to anticipate all the devices and screen sizes visitors to your website will use, it is important to have a website that is responsive. A responsive website provides a greater user-experience across the many screen sizes of today's devices.
If high natural search engine rankings are a goal for your web business, it is equally important to take into consideration Google's recommended configurations. Google has said that responsive website design is its recommended mobile configuration. This is because responsive websites have the same content and domain so it is easier for Google to index and organize the content of the site.
Another appealing aspect of responsive website design is being able to update and maintain one website.
