Go mobile: 2 websites in 1
Adaptive plus Responsive design
The responsive nature of your main site works across all platforms, but sometimes, strategically, it makes sense to change the emphasis for your mobile user. For instance, many clients decide that providing a mobile user with location and quick phone access is more imporant than business content.
Often the content on the main site is too verbose for mobile when a shortened version would work better. Perhaps you just don't want to overwhelm the mobile user. YWD can restrict pages and even right down to the content block on a page from displaying on mobile. It's your choice.
Easy to design, deploy & maintain
The same intuitive system used to create business websites without programming is used for mobile.
