Understandably, the vast majority of website readers devote most of their attention to the content and navigation elements that are present on any given web page as soon as it is loaded and displayed within a browser's window. If a web page's relevant content stretches down for several pages worth of space, a fraction of the audience will likely not bother to read all of it because the message and the substance of the content would not have been concisely collected and arranged near the top portion of the page where viewers typically land. Given this context, the content posted at the very bottom of a page is the least likely to be read intently by audiences; if this content is distinctly separated from that of the page's body, it is referred to as the page's footer.
Web designers who have supplied a website with its user interface tend to use the footer for technical information about the company owning the website, and it often contains a link pointing to a page featuring the company's contact information. Legal information such as copyright dates are also commonly found at the footer. This is often ignored by viewers as the "fine print" because it is expected to give none of the insightful content the website hopes to associate itself with as a whole.
However, since readers who take the time to read the full contents of a web page naturally end up in the vicinity of the footer, there are some niche purposes that web designers assign to the footer to subtly improve the website as a whole. It often features a compressed form of the navigation section that is usually seen near the top of a given page so that users do not have to scroll all the way back up to reach other pages, and it usually hosts external links to all of the company's social media profiles. Internal links can also be present to point viewers who had presumably read the content to related pages that might otherwise be too specific to include in the generic navigation sections.
