Marketing our businesses has changed. Everyone has mobile devices and they are using them to find what they need and want. Customers are looking for your products and services online. They are researching your business online before they contact you.
In April 2015, Google changed their search rankings to include mobile friendly criteria. If you have a current website and it is NOT mobile friendly, the site will be penalized and show up lower in the search rankings.
