Some good advice here overall.
Until recently, web page footers had a great deal of inattention lavished upon them. They were more of an afterthought than an important element of the page structure and design. This may have been due to a comparison to print publications where footers are seldom more than a page number, or, by the erroneous assumptions related to content 'below the fold'.
However, a good footer adds symmetry to the page architecture and a sense of closure or completeness for the user.
