Link Juice (Link Equity)
What Is Link Juice?
Link juice is an informal SEO term referring to the authority and ranking value that one web page passes to another through a hyperlink. When a page with established credibility links to another page, it transfers a portion of its authority, helping the linked page improve its standing in search engine results. The concept is rooted in how search engines evaluate the quality and relevance of web pages based on the volume and quality of links pointing to them.
The formal technical concept is link equity. Search engines treat links as votes of confidence from one page to another. A link from a highly authoritative, topically relevant page carries significantly more equity than a link from a low-authority or unrelated source.
How Link Equity Flows
Source Page Authority
Pages with high authority because they have accumulated strong inbound links themselves pass more equity. A link from a widely cited industry publication carries substantially more value than a link from a newly created website with no external references.
Relevance of the Linking Page
Topical relevance amplifies link equity. A link from a page covering a closely related subject signals contextual alignment to search engines, making the equity transfer more valuable than a link from an unrelated domain regardless of its authority level.
Number of Links on the Source Page
Link equity is distributed across all outbound links on a page. A page with two outbound links passes more equity per link than a page with 200 outbound links. Pages that link broadly dilute the equity available to any individual destination.
Link Attributes
Standard followed links to pass equity. Links marked with rel=’nofollow’, rel=’sponsored’, or rel=’ugc’ instruct search engines not to pass equity, though nofollowed links may still provide referral traffic and brand visibility. Links within the editorial body of content generally carry more weight than links in sidebars, footers, or navigation.
Internal Link Equity
Link equity flows between pages within the same website through internal links, not only through external backlinks. A well-structured internal linking strategy distributes authority from high-equity pages to priority pages that need ranking support. Cornerstone content pages consolidate the most authoritative content on a topic and should receive internal links from related supporting pages to concentrate on equity where it matters most.
Link Equity in Technical SEO
Technical issues can block or waste link equity. Pages returning redirect chains pass diminishing equity through each additional hop. Pages returning 404 errors waste any equity pointing to them. Canonical tags direct search engines to treat one page as the authoritative version when duplicate content exists across multiple URLs, consolidating equity rather than splitting it.
Key Takeaways
- Link juice describes the ranking authority and value that flows from one page to another through hyperlinks.
- Equity volume depends on the source page's authority, its topical relevance to the destination, the number of outbound links on the source page, and the link's attribute.
- Internal linking distributes equity across a website, making it a controllable lever for improving the rankings of priority pages.
- Technical issues such as redirect chains, broken links, and duplicate content without canonical tags waste link equity that could otherwise support search performance.
- High-quality, topically relevant backlinks from authoritative sources are the most valuable equity inputs for improving organic search rankings.
