Building Websites That Respond Across Multiple Devices

All web developers should be building responsive websites using a simple line of code in the head. When developing a website, you want the browser to render the website's screen-width to match that of the user's desktop or mobile device. You can use the viewport meta tag (meta name=“viewport” content=“width=device-width, initial-scale=1.0) to accomplish this. Initial-scale=1.0 sets the zoom level; one CSS pixel equals one viewport pixel. Without viewport meta information, mobile users would see a shrunken version of your website that provides a poor user experience.
As new devices hit the market, a responsive website will help you keep up with the changes by future-proofing your website. Your site will support users with new devices with unique screen sizes on smartwatches, game consoles and more.
Using the viewport meta tag and making your website responsive is better than offering a mobile-only approach with a separate mobile-optimized site. When visitors using a mobile device visit your website, they may see reduced content and functionally on the mobile version of your site. This can lead to confusion and frustration if the person's first visit was on a desktop. Additionally, two websites are twice as expensive to develop and twice as time-consuming to update and maintain.
As you can see, if you are hiring a web developer, make sure they are building you an easy to maintain, a future-proof website that adjusts to the user's screen size.
Finally, Google rewards sites with multi-device support; how a site is built can be an important factor in SEO. People hit the back button right away if a site doesn't render correctly as well, which increases your bounce rate. Bounce rates are also one of Google's ranking factors. While the whole idea of building a responsive website is to provide a better user experience, an added SEO boost can't hurt.
