Link equity
The ranking value passed through a hyperlink, influenced by the linking page's own authority, its relevance, its number of outbound links and the link's attributes.
In full
Equity is diluted across a page's outbound links, which is why site-wide footer link blocks pass little and a contextual link from a well-linked article passes more. It is lost or reduced by nofollow-class attributes, by redirect chains and by linking to noindexed or 404 pages. Internally, equity is a resource you allocate deliberately through navigation, hub pages and contextual links.
Example
Adding links from three heavily-linked guides to a new commercial page moves it from position 18 to page one within a month.
