One thing a lot of smart businesses, small and large, are understanding is that their brand is communicated through the way users interact with their online content. If that interaction turns out to be a bad user experience, then it will be completely reflected on the brand and vice versa.
If your site is optimized for mobile you are able to positively communicate your brand to this fast growing crowd of mobile internet users. On the other hand, businesses who are not keeping their eyes on the numbers and trends will be left behind faster than they can imagine.
