The site reponds to the device it's viewed on
Responsive designed sites work on a fluid system that will resize and reorganize content to provide the perfect viewing of your content
no matter the device it is viewed on.
Superior User Experience
Without a great user experience, you are unlikely to have your site visitor view the content of your site. Responsive web design is all about an optimal user experience irrespective of whether they use a desktop computer, a smartphone, a tablet or a smart-TV. Responsive web design allows your site to fit into anyone’s lifestyle and gives them the opportunity to view your site without scrolling or resizing. Your site is perfectly presented for any visitor from their favorite device.
Google Values Responsive Design
Google has stated that responsive web design is its recommended mobile configuration. Google has also referred to mobile friendly web design as the industry best practice.
One reason for this is because it is easier and more efficient for Google to crawl, index, and organize content of a single responsive
site. Compare that to a separate mobile site which has a different web address to its desktop counterpart, requiring Google to crawl
and index multiple versions of the same site. Then add in a tablet and a smart tv version, you can quickly see why google prefers
Its all about the money
Having multiple versions of a site designed will cost substantially more than a single responsive design.
Imagine a client asked you for your website address and you had to first find out what device they will be viewing it on. It would
probably not create the best impression and would possibly provide your competition’s site with a visitor instead. It will also cost
more for SEO on multiple sites as opposed to a single site that receives all of your web traffic.
