Smartphones have officially taken control of the internet. People use them to search more often than they use desktop or laptop computers. Statistically speaking, it is more likely that a person browsing your site will use a phone to do it than any other device.
In response, Google has turned to mobile-first indexing. This puts a priority on sites that have been optimized for a mobile experience. Are you ready for the change? The way you respond can dramatically impact your page rank and your site's exposure moving forward. The change is here to stay, and odds are that the mobile numbers will only continue to increase.
