Over 50% of all web browsing is now done on a mobile device, whether it be a phone or tablet, and this figure is growing as more people browse whilst on the move, walking through town looking for a restaurant!
If you're not able to reach your audience through mobile search or display, or you're not providing a satisfactory mobile experience you will miss out compared to competitors who are.
Having a separate desktop and mobile site requires having separate SEO campaigns. Managing one site and one SEO campaign is far easier than managing two sites and two SEO campaigns. This is a key advantage a responsive website has over a separate mobile site. As content is managed in a single place, there is a huge time saving too.
With 67 percent search market share, when Google speaks, search marketers listen. Google states that responsive web design is its recommended mobile configuration, and even goes so far as to refer to responsive web design as the industry best practice.
This is because responsive design sites have one URL and the same HTML, regardless of device, which makes it easier and more efficient for Google to crawl, index, and organize content. Contrast this with a separate mobile site which has a different URL and different HTML than its desktop counterpart, requiring Google to crawl and index multiple versions of the same site.
One of the most appealing aspects of responsive web design is that a responsive website can provide a great user-experience across many devices and screen sizes. This is an important characteristic, since it is impossible to anticipate all the devices and screen sizes searchers will use to access your site. A site that works well regardless of these variables will provide a better and more consistent user-experience than a separate mobile site that is designed for a specific device and screen size.
