- Tuesday marks what many are calling "mobilegeddon"—the day when Google changes its search algorithm to favor mobile-friendly sites.
- Some media outlets are reporting that as many as 40% of websites today are not mobile-friendly—meaning the change in mobile search results could be dramatic.
- To check if a site is mobile-friendly enough, Google has created a URL tool to help.
The algorithm changes will likely cause a big shift in how search results are displayed on mobile devices. That idea is concerning to a lot of marketers who are worried about losing SEO position that has taken time to build.
If a site isn't already optimized for mobile, being at the top of a mobile search list does little good because mobile users will be frustrated with slow load times and hard-to-read text. Mobilegeddon could light a fire under brands that need to move into mobile anyway to stay current.
Below is a timeline from marketing agency DPFOC charting the history of Google's previous algorithm updates and related news.
