This all depends on how much content you have. Every business website should have an 'About Us' page (or something similarly titled) to tell your visitors about your business. After that, it depends on what type of business you have. A good rule of thumb is to not overwhelm your audience with too much information on each page. Disperse the information and break it up into digestable pages and paragraphs. Long pages of text tend to overwhelm the reader. Break content up to truly get your audience's attention.
