Are links in footers treated differently than paragraph links?
In the original PageRank paper, link value was allocated uniformly no matter where they were on the page whether at the top or the bottom or in a footer.
What we compute today is still called PageRank.
In general, our link analysis continues to get more and more sophisticated. It bears resemblance to the original PageRank.
We do reserve the right to treat links in footers a little bit differently. For example if someone has set up a footer with a link that is carried throughout the site, this would not be as important as a link within the text.
