The standard shop site is a homepage, an about page, a list of services and a gallery. It describes the business. The person landing on it is standing next to a damaged car, on a phone, with an insurance claim open, and they will give your site well under a minute before calling somebody.
What they need to know is whether you work with their insurer, whether they have to use the shop the insurer named, how the car gets to you if it does not drive, and whether you have fixed their kind of car before. A site that answers those four things on the first screen gets the call. A site that answers them on page three loses it to the shop that did not make them look.
We know which questions matter because we take the calls. The site we built for our own shop is organised around them, and so is every shop site we build.
