Link Juice

Link juice is an informal term for the ranking value or authority that passes through a hyperlink from one page to another. When a page links to another page, it transfers a portion of its own credibility and strength to the destination, and that transferable value is what practitioners nickname link juice. The metaphor pictures authority as a fluid that flows across links, filling up the pages that receive it and helping them rank more strongly in search results.

Mechanically, link juice reflects the underlying logic of link-based ranking. Search engines treat a link as a vote, and the more authoritative the linking page, the more valuable its vote. That value flows to the linked page and can, in turn, flow onward through the links on that page. Several factors affect how much passes: the authority of the source page, the number of links on it (since the value is effectively shared among them), the relevance of the link, and whether the link is set to pass value at all. Links marked with the nofollow attribute, for example, are designed not to pass this authority, while ordinary dofollow links do. Both external links from other sites and internal links within your own site carry link juice, which is why internal linking can be used deliberately to channel authority toward the pages that matter most.

The term arose in the early 2000s within the SEO community as a vivid shorthand for a concept that search engines never officially named this way. "Juice" was chosen to picture the ranking value squeezed through a link, an intuitive image for something that is really an abstract algorithmic weight. It grew popular because it made the flow of authority easy to talk about, even though it simplifies a more complex reality.

For a business, understanding link juice matters because it explains why some links help far more than others and how authority can be steered within a site. Earning links from strong, relevant pages brings more value into your site, lifting your ability to rank. Meanwhile, thoughtful internal linking lets you direct that incoming value toward high-priority pages, such as key product or service pages, rather than letting it pool on less important ones. Recognizing that value is shared among the links on a page also encourages cleaner, more purposeful linking rather than cluttering pages with dozens of competing links.

There are important nuances. Link juice is a simplified metaphor, and modern search ranking involves many signals beyond raw link value, so treating it as the whole story is a mistake. Obsessing over "sculpting" the flow by aggressively marking internal links as nofollow is generally counterproductive and outdated. Another error is assuming all links pass equal value; relevance, trust, and placement all matter, and a link buried in a footer differs from one embedded in relevant content. It helps to view link juice alongside related ideas such as link building, which brings value in, dofollow links, which pass it, and the internal links that distribute it. The practical takeaway is to earn authoritative, relevant links and then guide their value internally toward the pages you most want to succeed.
