A lot more people can find you
Having a website for your business increases the number of people, and therefore potential customers, who can find you. You are not limited geographically, and so anyone around the world can find your business. Another sale is literally a click away!
You are available 24/7
Your website is always active, meaning potential customers can find you any time of the day, any day of the week. You can make a sale on your website at any time! Perfect for customers who may not have time to come to your shop during the day.
People research products and services on the internet before purchasing them, so it's best that your business is there with information on your products and services, yet again increasing chances of a sale. Also you can interact with your customers more via blog posts and membership areas which builds a more loyal relationship!
