There are now more mobile devices in the world than humans. More than 7.2 billion mobile gadgets to be exact. Clearly, the future belongs to mobile devices.

Google understands this better than anyone and the company is now focusing on improving its search engine to provide a better experience to mobile users.

The mobile-friendly search algorithm, which Google rolled out in 2015, now punishes websites that aren't optimized for mobile devices. Needless to say, if your website isn't optimized for mobile devices, you will never be able to rank in the top search results pages due to Google mobile friendly guidelines.
