With an ideal design, you can bring about easy navigation, page access, and also access while on the move. A fast download time, flexible compatibility, greater conversion, and better sales is possible. You can even see direct sales from the mobile users. Users can be lured to the site even if they are offline. This is because the responsive design uses HTML 5, which enables users to easily subscribe to the newsletters and contents that they can view during the move without any hassles.

We'll review and compare the differences between a separate mobile site vs. responsive design… and why Responsive Design is better.
What Is a Mobile Site: In a nutshell, a mobile website is a copy of your website where the server does the work to deliver the page that is smaller and easier to navigate.
You usually create a different domain; i.e. "m.company.com"

What Is Responsive Design: Responsive design is one site that adapts to the viewer's device whether it is a laptop, Smartphone, or tablet. Responsive is a design technique that automatically resizes and adjusts the website on various device screen sizes and orientations. Content for all devices is thus served from the same domain.

Maintenance (Time is Money): A separate mobile site needs TLC too! Creating a mobile site means having a separate mobile domain. Consider not only the cost of maintaining a second site; chances are you will have to update your mobile site every time you update your desktop version! And of course, with a mobile site, you have to update it in accordance to new phones, tablets, mobile browsers etc… Time is money!

Responsive design means one site for multiple devices, so maintenance is easy… one website is cheaper than two.

The Responsive Website Concept: Responsive website design (RWD) is a user-friendly design that enables your site to resize or adapt itself dynamically on whatever device it is viewed on irrespective of the screen size. In other words, you can view your site easily both in a small screen like your mobile, and a big screen like desktop the same way. The panning and scrolling is diminished greatly with this technique. The design boosts user experience, improves conversion rates, and brings better exposure for your site.

Mobile Site vs. Responsive: Many people would wonder why go for a responsive design, when there are mobile apps! Mobile apps are used for a certain specific purpose only. They are used in brands that have a loyal customer base. Google Prefers Responsive: Responsive design has one URL and the same HTML, regardless of device. This means that it is easier for Google to crawl, index, and organize content. Don't take our word for it, check out "why responsive design" from Google.

The apps help to find store locations, access your account, and find about special offers. But as the name implies, the site responds optimally to any medium it is present on. For instance, a site can have three columns and a single sidebar when viewed from a desktop, whereas from a mobile or tablet a simplified version with less columns and simple navigation is present.
