What do the advanced options do for network diagrams?
The link network can be changed to a co-link network. This is similar to a link network except that the links counted are not the total links between a pair of web sites/URLs A and B but instead the total number of pages linking to both A and B is counted. This is an indirect form of link counting. Pairs of web sites or URLs that are similar tend to have higher link counts, so colink networks tend to cluster similar sites together.
