On April 21, Google will rolled out an algorithm change. It was one of the largest algorithm changes ever made. The change is meant to help provide better results to people who search Google using mobile devices. If your site is not designed to be mobile-friendly, your rankings will likely decrease substantially if they have not already. You can test to see if your site is mobile using Google’s Mobile Friendly Test Tool.
We recommend a responsive website which will work on devices of all shapes and sizes. If your site is not mobile-friendly, your rankings will likely drop, but if you fix it they should recover. Please contact us if you would like to learn more.
