### Position in the link graph

The graph holds the active and blocked sites in the census and the links between them: 313,844 sites. Rank 1 is the highest.

- Links in (in-degree): 1 site in the graph link to it
- Links out (out-degree): it links to 5 sites in the graph
- PageRank rank: 118,751 of 313,844
- PageRank rank without footer-only links: 88,818 of 313,844
- PageRank rank between registered names: 259,215 of 313,844
- Betweenness rank: 45,690 of 313,844
- Sites reachable by following links: about 61,833 (estimated)
- Community: one of 5,762 sites in its Louvain community

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.

Every link of the site, with where on its pages it was seen: links in (1) https://palo.dirishwago.co.za/explore/sa3.ac.za/links-in.md, links out (10) https://palo.dirishwago.co.za/explore/sa3.ac.za/links-out.md

## About these figures

- A domain is a name registered under a .za zone, such as uct.ac.za, with the sites under it, such as lib.uct.ac.za. Its status is the best of its sites': active, then unavailable, then blocked, then dead.
- Only links between .za sites in the census are counted; links from outside .za, social media and search engines are not observed.
- Links added by scripts after a page loads may be missed, and pages Palo has not crawled are not seen.
