- PageRank rank: 12,539 of 236,237
- PageRank rank without footer-only links: 9,120 of 236,237

Definitions: in-degree and out-degree count links from and to other sites in the graph. PageRank weighs links by the rank of the sites they come from; every link counts the same, whatever its purpose. Without footer-only links, it leaves out links only ever seen in a page footer. Between registered names, it leaves out links between sites under one registered name, such as x.co.za and shop.x.co.za. Betweenness measures how often a site lies on the shortest paths between others. An island has no links to or from other sites in the graph; an unrecognised site links out but has no links in. A Louvain community is a group of sites more densely linked to each other than to the rest.
