In your website you should link all of your important pages to all of your other important pages. This is a pretty straightforward idea but it's not always executed. Inter-linking your important pages is important for visitors so that they will be able to easily navigate the important pages on your website. Inter-linking is also important for the search engines who may enter your site on any given page. If this page links to your other important pages it will be easy for them to follow along, indexing these pages as they go.
