These days most people search on Google from a mobile device. Google has been ranking sites based on the desktop version of a site. However, Google is shifting focus to mobile versions of sites to reflect how people are now using their service. Google's analysis has shown that 70% of websites are mobile-ready. This leaves many sites unprepared for the shift in search results coming in September 2020.
Google uses the Googlebot crawler to index mobile sites. It uses a mobile browser to view sites for indexing. Sites without mobile optimization will be ranked poorly by Googlebot's crawler as it indexes a site. Google will eventually index the desktop version of a site once all mobile sites have been indexed. But until a desktop-only site is indexed by the desktop Googlebot, it will sink lower down the Google search results costing you valuable leads.
