Link graph
The network of all pages as nodes and hyperlinks as edges, over which link-based ranking algorithms such as PageRank are computed.
In full
Search engines maintain their own view of this graph, which no third party can replicate — commercial link indexes crawl a subset and model the rest. Analysing the graph reveals clusters, hubs, authorities and artificial structures such as link networks whose interlinking patterns are statistically unlike organic ones. Internally, a site's own link graph determines crawl efficiency and equity distribution.
Example
A backlink tool shows 40 referring domains that all link to each other and to the same 12 clients — a recognisable network pattern.
