Do you have a mobile-friendly or responsive website? If not, on April 21 you may find it harder to rank in Google’s mobile search results.
Google recently announced algorithm updates that will have a “significant impact” on mobile search results worldwide for mobile searchers. The update improves rankings for sites that provide a mobile-friendly experience to searchers on mobile devices, and, by association, demotes sites that do not.
Note that the mobile-friendly update only affects mobile search results — i.e., searches from smartphones and tablets — not searches conducted on a desktop or laptop computer.
