A company website is any website dedicated to the portrayal of a particular business. It should be marketed as a company (same logo and positioning) and convey the types of goods and/or services provided by the business.
By now, any company out there is expected to have a site. This is a popular anticipation. Any latent customer you meet can just presume that if your company is searched by Google for more material, they can find a website. And if they’re not, it makes the company seem less competent or legitimate.
E-commerce websites are business websites, but it is also possible to have business websites that do not sell something directly, but rather allow people to get in touch for more details (lead generation website) or to go to the storefront if they are interested in becoming customers.
