This past year wasn't a huge one for Google algorithm updates, as there were only two major, verified changes that occurred. However, even though the changes weren't significant, they have some big implications for the future of search engine optimization (SEO), and are definitely worth acknowledging.
Google Bets Big on Mobile
The first big algorithm update of 2016 happened in May, when Google put even more emphasis on the ever-expanding mobile market. According to Search Engine Land, Google's aim was to build on 2015's mobilegeddon update and boost up pages that either had responsive or mobile-friendly designs. Though this update doesn't punish websites without mobile versions, it does lay the groundwork for a more substantial mobile update in the future, which could arrive later this year. This why you should optimize your website for mobile now. In fact, Google even has a mobile-friendly test you can use to see where your page stands and learn about any improvements that should be made.
