Link Juice - Use 1

Link juice often refers to the link value a link is able to pass on to the target.

Many assume this would be only a metric defined by the link graph, e.g. the LRT Power, Ahrefs UR or in the page Google PageRank.

Other aspects, namely link trust, anchor text relevance, organic rankings in quanitity and quality are important to consider tough when talking about a generic concept like link juice.

Link Juice is often used as a simplification of an underlying system to evaluate links. In absence of knowledge or name for accurate metrics for a link SEOs often use it there to differentiate between weak and strong links.

This term link juice has been used since the early 2000s and stuck around in blogs, forums and social media.

Some people in the SEO industry mention they dislike the term "link juice", often because of the vague (no) definition of it.
