The link graph is the search engines source for developing trust, authority, popularity and importance.

To begin, we need to understand the different domain levels. There are two levels:

  • Pay level domain – *, for example. This is that part you pay for.

  • Fully qualified domains – similar to a subdomain, all the levels under the pay level domain.

There are also many levels of link graph:

  • Internal link graph on the fully qualified domain

  • Link graph within the pay level domain

  • Link graph of the web

The link graph contributes to the following metrics:

  • Page rank

  • Domain-level page rank

  • Trust rank

  • Domain-level trust rank

  • Spam metric

  • Domain Juice
