Creating responsive websites is more important than ever. Google has added mobile-friendliness as part of their search algorithm for mobile devices, and a growing number of people are accessing the Internet from an array of mobile devices, and the number of users keeps growing every year. With the escalation of this trend, it is no longer optional to support mobile responsive design when programming websites for customers. Sites that are not mobile responsive will be downgraded in Google's search engine. It is time to act and add mobile responsiveness to your repertoire.
