Do you have a mobile or responsive site? If not, on April 21 you may find it harder to rank in Google’s mobile search results.
Google 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.
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.
In addition, the algorithm is applied worldwide, page by page, on a real-time basis. “Worldwide” means that the algorithm update affects mobile searchers and search results in all countries at the same time, rather than just rolling out in the U.S. first.
