“These days, there are two predominate ways that users get to a web site. Either they type the URL into the address bar, bringing them to the site’s home page, or they come to the site through an aggregator or referral, such as Google, often taking them to a specific page within the site. For some sites, the home page is the most popular route, but increasingly, users link deep into the site.” (Jared Spool – User Interface Engineering)
