Author: Bill Ross | Reading Time: 3 minutes | Published: November 7, 2025 | Updated: March 6, 2026 Launch Date: April 21, 2015 By the spring of 2015, mobile search had been happening for a while. But many sites had neglected to optimize their sites for mobile use, without consequence. Google decided that it was time to put sites with no or poor mobile usability at lower ranks than sites with excellent mobile design. Before this change, they were frustrating their users and providing a terrible search experience, especially since much of Google’s search happened—and continues to happen—on mobile devices. The Mobile update put a stop to that. The Mobile update is all about creating the best experience for users on mobile devices. For this reason, the huge triggers for this algorithm update are poor mobile usability. If a site doesn’t have a mobile version, or if a site does have a mobile version, but it’s hardly usable, your rankings will feel it. The dangers associated with the Mobile update are significant for poorly optimized sites. If your website design ignores mobile users, has poor navigation, unreadable text, slow load times, and difficult-to-use features, it increases the risk of being downranked. Google’s web crawlers will detect these issues and can demote your site in search results. At this point, you know the goal of the Mobile update: cater to mobile users. Mobile is the way of the future, and really, of the present. There are a few things you can do to ensure your site serves mobile users and ranks high on Google’s SERPs. The Mobile update works in real time: once your site is mobile-friendly, Google’s crawlers can reprocess your pages, potentially improving rankings quickly. You can request a recrawl to speed up the process. The most efficient approach to mobile optimization is to engage SEO experts for a comprehensive audit. A thorough evaluation of your site will identify key areas for improvement to ensure an optimal mobile experience. Achieving mobile compatibility enhances visibility and maximizes audience reach.
