Most people don’t leave their house without their cell phone or some kind of mobile device. This is great in emergency situations, like when a car gets a flat tire. If someone is broken down on the side of the road they are going to call a towing service, but chances are they don’t have a towing service in their contact list.
Instead that person will open up their web browser (on their Smart Phone) and search for a local towing service. When they start looking through the search results they will look for a site that is easy to read on their phone. If your website is not optimized for mobile you are missing out on this opportunity. And just so you know, Google gives extra ranking power to sites that are mobile friendly.
So if you are a local towing service or tow truck company you need to get a mobile friendly website.
