Responsive website design is very important in presenting a consistent brand image across all devices, it’s not just about mobile search ranking.
What responsive web design means, is the ability of your websites’ layout to adopt to every size of screens, regardless being large or small.
In many cases, mobile-friendliness gets overlooked, in some other cases is just a requirement and for others just another feature. The bottom line is that responsive design has a huge impact on the overall performance of not only your website but also your marketing strategies.
