Google is dispatching mass scale warnings to non-mobile friendly websites, indicating that new mobile algorithm may be coming soon. As revealed by Search Engine Roundtable, the notifications are sent through email and webmaster tools warning sites that their incompatibility with mobiles will cause ranking issues for them.
The notifications have the subject “fix mobile usability issues found on…” They mention that the site has critical mobile usability errors on 100% of the pages, which will affect the display as well as rank for smartphone users. Sending notifications to non-mobile friendly websites is a step beyond the broken mobile site penalty Google had in 2013.
This drops hints about the new mobile ranking algorithm to be launched by the search engine giant. Google has been experimenting with it for a time. They also put up mobile-friendly labels in the search results, mobile friendly testing tool and mobile usability reports in Google Webmaster Tools.Google Sending Notifications to Non-mobile Friendly Websites to Fix Mobile Usability Issues,
