Google updated their algorithm on 20th April 2015 to improve the ranking of websites that are a mobile friendly website. Conversely, websites that are not mobile friendly are demoted in the rankings.
If you have a website that is not responsive, and not mobile friendly, the only option may appear to be a complete website redesign. This is not necessarily the case as we have a mobile website builder. From only £60+VAT per year you can create a mobile version of your website with an easy-to-use interface that provides great results.
