Link equity (also known as link juice) is the value or authority that passes through a hyperlink from one site to another. When a site links to another site, it is casting a vote. The more authoritative and relevant the linking site is, the more link equity it passes on to the target site. Link equity is important because search engines have their own algorithms that consider link equity as validity and legitimacy in determining a website according to the results it presents for the search engine rankings. Thus, one should earn backlinks to build link equity and increase one’s SEO performance from good-quality sites.
