If you don’t have a responsive website, then Google will force your ranking lower
Yet again we’re having to bow to the universal god that is Google, but it makes sense, whatever message you have on your website, will not only get seen on desktops, but also on a whole multitude of devices from tablets to smartphones. A responsive website is one that resizes itself into a wide variety of devices, seamlessly.
So the answer is yes, your website now needs to be responsive, if it isn’t, then you will undoubtedly be missing out on a massive sector of the public, many of whom see their smartphone as the device of choice for browsing the internet, particularly when out and about.
If you’re considering revising or renewing your website, your first port of call should be WordPress, which is a content management driven system, allowing your many advantages. Most of their ‘themes’ are configured to be responsive, so you know it’ll work straight out of the box – metaphorically speaking.
