matter – not all links are valued the same. Keep in mind that PageRank is but a single (albeit important) factor used in ranking

Sites that are highly optimized for on-page factors can outrank sites that are less
optimized but have higher PageRank.

PageRank value is assigned after comparing every page in the Google index against
one another. This is billions and billions of web pages.

Note that PageRank does NOT factor in keywords or phrases used on your site.
