In April 2015, Google changed their system so that it gives preference to websites that are mobile friendly and penalizes those that aren't. If you have an older website, you could experience a dip in your search rankings, especially if the search is conducted from a mobile device. Having a mobile friendly website is actually pretty huge these days. On average, 50% of our website traffic comes from phones and tablets.
And if your current website loads funny or doesn't load at all, or even just takes a bit of time to load on a phone, that customer is gonna go bye-bye. But don't worry, every website we make is automatically mobile friendly right from the start. Your site visitors will experience fast load times, and a clean design that automatically resizes the fonts and realigns the images on the fly so they look great no matter what type of device they're using. So even if you're reasonably happy with your old website, it's probably time to think about bringing it into the modern age.
