“Google has not only added mobile-friendly tags next to sites in the search results, but also hinted at penalizing a site’s Google rank for not being responsive [meaning the website automatically adjusts for people viewing on mobile devices],” says digital marketing expert Ken Wisnefski.
“Google wants to remain the number-one search engine, so if more people are utilizing mobile than desktop, it is going to push the sites that are mobile to the top of search results. Companies that don’t implement mobile design changes will be invisible on search.”
