Once a visitor gets to your web site, you want to make sure they can find what they are looking for quickly and easily, or they will just go elsewhere. Search engines should be able to navigate easily through your site. Making a site easy to read with consistent page design, and easy to navigate will make it easy to find information.
When people can find information, they are more likely to refer your site or link to it, which is exactly what you want to encourage. You will be on the way to building a readable and hopefully successful website that is loved by search engines if you follow these principals. By having a menu that is on every page of your site, users can move from each section from any other section, with out having to go back to a home page or menu page.
