Today's business websites have to function well on mobile phones, content needs to readable and navigation has to be simple and intuitive. More than 50% of websites are now viewed on mobile devices so it is no longer acceptable to have a non mobile friendly website. That is; a site that needs to be zoomed in to navigate, where content and images do not resize and adapt to the viewing window.
Fortunately, every Blue Web designed website is mobile friendly and has been for a number of years.
Google now checks every website for mobile friendliness and if the site is found to be unfriendly then it is marked down in Google ranking.
