Not all websites are eCommerce websites – that is, websites that are designed so that people can buy products directly online. They might instead be brochure websites, where people can look up a business, find out more about them, see what services they offer, and then get in touch with the business. This is generally what people who own service based businesses will do, to attract new clients without having to rely on in-person marketing.
A brochure website is also something you can direct people towards if they want to know more about your business. For example, you can tell someone who is interested to go onto your website and see photos of your work, or to see your full price list. Then, when they are on your website, they can also find out more about you and will begin to understand your business better. This is a very good tactic for many businesses.
