Is your website responsive?
A responsive website automatically adjusts to every screen width, so it’s easy to read and use whether you’re using a laptop or an iPhone. For example, a three-column layout might become a 1-column layout on an iPhone.
Google has announced that the mobile search results are about to change completely. If your website isn’t responsive by April 21st, it may rank lower or even disappear in Google’s search results. Read more about the changes here.
