There is no e-mail, telephone number or fax number. We've even been on pages where even the ownership of the page is not shown. By backing out of the page to the opening page of the site, such information is usually available but that extra step might be too cumbersome for some users. Sometimes the reason for this apparent oversight is an assumption that users always navigate the site from the home page onward. This is not a proper assumption.
Users can land on any page of any site.
Therefore every page on a web site should provide clear identification as to who the owner of the site is and how to make contact. A simple way of doing this is to provide concise contact information at the foot of each page. This is in addition to clear navigation to the rest of the site. In addition, there can be a page dedicated to more detailed contact information. A large organization might have several departments each with its own telephone numbers and e-mail addresses.
