On Tuesday, April 21, Google is making a major update to its mobile search algorithm that will change the order in which websites are ranked when users search for something from their phone.
The algorithm will start favoring mobile-friendly websites (ones with large text, easy-to-click links, and that resize to fit whatever screen they're viewed on) and ranking them higher in search. Websites that aren't mobile-friendly will get demoted.
About 60% of online traffic now comes from mobile and Google wants users to have a good experience whenever they click on a mobile link.
The company announced its impending changes back in February, giving webmasters nearly two months and plenty of information to make the changes necessary to keep their sites from disappearing from mobile search results. But the update is still expected to cause a major ranking shake-up.
