Link equity, also known as link juice, is a term used to describe the value or authority passed from one page to another through a hyperlink. When one webpage links to another, it is essentially vouching for the quality and relevance of the linked page. The amount of link equity passed from the linking page to the linked page depends on various factors, such as the authority of the linking page, the relevance of the linking page to the linked page, and the number and quality of links on the linking page.
