Google is dropping the non-mobile friendly sites from their listings.
You can read about it on the BBC web site. http://www.bbc.co.uk/news/technology-32380223
The test is https://www.google.com/webmasters/tools/mobile-friendly - all you do is put a website URL into it.
Needless to say IntrepidDigital can address this problem so contact us now before you drop off the Google search result lists.
