If you're talking about Pagerank, it has nothing to do with on page content. Pagerank is 100% links.
I want to emphasize this point loud and clear. Too many people around the web are spreading ideas that PageRank has something to do with keywords, or content, or relevance. It does not. PageRank is what Google calls a "query-independent" factor in the algorithm, just as trust is also query-independent.
No content involved in a PR calculation, no keywords either - just links, links and links.
Google has shifted the original formula around in ways we are not sure of - mostly bout when they do or don't count a link and how the split up a page's total PR vote. But the content parts of the overall algorithm, the "query-dependent" factors are completely separate from PageRank.
The idea behind PageRank was that people give you a link because they like your content. But to have a PageRank effect, the link has to be there, not just the part where "they like it". Google cannot directly measure something as hazily defined as "quality content."
