The advantages of having a single site that conforms to the need of all devices are significant when compared to having two separate websites. One website costs less than two, and the savings can be substantial. Sites designed solely for mobile device traffic don’t offer the advanced navigational techniques found in traditional websites, and they also require the user to maintain two separate web addresses for your site. This is inconvenient for most people and can cause them to check out the competition’s website. Responsive web design enhances SEO efforts by having all your visitors directed to a single site no matter what they prefer to use as a device.
