This is a brief introduction to graph theory as it applies to both internal and external link building. The concepts here will be re-used in future posts, and I’ll refer back regularly.
It’s my guess that Google has hired numerous employees with PhDs in Mathematics for a variety of reasons, one being that their PR (PageRank) algorithm requires a graph theoretic approach to analyzing links, to determine whether or not they are “natural” and “organically grown”. Before getting too deep into analysis, which I’m leaving for later posts, let’s have a look at a few types of simple link structures for any collection of sites. For convenience, I’m referring to each collection here as a “network”, thought that does not mean the same person owns all the sites.
