In today's day and age, it is absolutely necessary for every business to have an awesome online presence. It's not enough these days to have one social media page. You really need to have an awesome website and incredible social media pages in order to make the most of every potential customer. Even if your business doesn't sell online, potential customers or current ones expect to find you online with 1 google search. If they can't it tells them a lot about the size and quality of your business and you could be missing out on sales.
Right now, if anybody wants more information about a business they're very likely to start online. They may be looking for your company after a friend mentioned you or they could be looking for anybody who offers your product or service. If you aren't online, how will they find you? You need to be quick and easy to find if you want to stand a chance against all your competition. A customer should be able to do one Google search and find all they need to know about your business, what you offer and how to contact you.
This is your chance to showcase 24/7 the products and services you can offer. You could share your work portfolio, client testimonials or pictures of your new product line. It makes it so easy for potential new customers to find what you offer and make a purchase or get in touch with you. You don't have to spend thousands outfitting a physical store when you can spend less and reach more people online. Your online presence is an extension of your business that has the potential to reach thousands around the world.
