Link equity (or “link juice”) is a way to describe the value that one page passes to another through hyperlinks. It is not an official Google metric, but an interpretive model inspired by PageRank: it represents the extent to which a page’s authority and relevance are transferred to other pages through links. Search engines treat links as a trust signal: the more authoritative a page is, the more value it can pass on.
The concept is central to SEO because it helps explain why some pages rank better than others even when their content is similar. Understanding how link equity is distributed lets you design a more effective internal and external linking structure, connecting important pages well. It is not a metric you can see in tools, but an interpretive model used to guide optimization strategies.
How authority passes from one page to another
When page A adds a link to page B, part of A’s value is transferred to B. This transfer is never total: in the PageRank model a damping factor reduces the value passed along the chain of links. This phenomenon is known as dissipation or decay of value, and it means that a direct link is generally worth more than a link that goes through several intermediate steps.
The value passed also depends on the topical relevance between the two pages, the position of the link within the content, and the total number of links on the source page. A page with many outbound links spreads its authority across more destinations, reducing the share assigned to each one.
The weight of internal links in distribution
Internal links, meaning those pointing to other pages on the same site, are a direct tool for distributing link equity within a domain. A clear navigation structure and a coherent link hierarchy help concentrate authority on the pages you want to rank. The most important pages should receive links from multiple points on the site and from pages that are themselves authoritative.
The contribution of external backlinks
Links from other sites, called backlinks, are the main source of external link equity. The quality of the source domain, its relevance to the topic and its overall reliability influence the value passed. A single link from an authoritative source can be worth more than many links from low-quality sites.
What determines the value of a link
Not all links pass the same value. Several elements contribute to determining how much authority passes from one page to another, and their combination produces very different effects on SEO performance.
| Factor | Effect on link equity |
|---|---|
| Authority of the source domain | A more authoritative domain can pass more value |
| Topical relevance | Links from pages related to the topic are generally more meaningful |
| Number of links on the source page | The more links present, the smaller the share for each one |
| Nature of the link (no attributes, nofollow, sponsored, ugc) | Google treats nofollow, sponsored and ugc as hints: it may not pass value, but it may also use them |
The combination of these factors explains why two apparently similar links can have very different impacts. A deliberate strategy seeks links from authoritative and relevant sources, placed naturally within quality content.
Nofollow, sponsored, ugc and value transfer
When a link has the nofollow attribute, the publisher is asking search engines not to give it credit. Since 2019-2020 Google treats it as a hint: it may not pass value, but it may also use it. The sponsored and ugc attributes signal commercial or user-generated links and are also hints. For details, see nofollow link.
There are also attributes designed to indicate the nature of the link, such as those for sponsored content or user contributions. Applying them correctly is important to follow search engine guidelines and avoid possible penalties. Improper use of these attributes can alter the distribution of authority and compromise results.
301 redirects and canonical: consolidating value
When a page changes address, a 301 redirect to the new URL consolidates signals on the destination: Google has confirmed that redirects do not lose PageRank. The rel=canonical attribute also indicates which version of duplicate or very similar pages should receive the signals. Orphan pages, with no internal links, remain outside the site’s value distribution.
Practices to better distribute authority across pages
Careful management of link equity requires action on both the site’s internal structure and external relationships. Below are the most common practices for improving the distribution of value across pages.
- Define a clear page hierarchy, with main pages easily reachable from the home page.
- Add relevant internal links within the body of content, not just in navigation menus.
- Do not use nofollow on internal links to concentrate value: it hasn’t worked since 2009. To exclude a page from results, use noindex.
- Correctly mark sponsored and user-generated links with the appropriate attributes.
- Fix or remove internal links that point to non-existent pages or server errors.
- Acquire backlinks from authoritative sources relevant to your industry, prioritizing quality over quantity.
- Periodically monitor your inbound link profile to identify toxic or harmful links.
- Update your most authoritative content to maintain its relevance and attract new spontaneous links.
Applying these practices consistently helps strengthen strategic pages and improve the site’s overall visibility in search results.
Frequently asked questions about link equity
What exactly is link equity?
It is the value or authority that one page passes to another through a hyperlink. Search engines use it as one of the signals to assess the importance of a page.
Is link equity a measurable metric?
There is no official tool that measures it directly. It is a conceptual model that helps interpret search engine behavior and guide optimization choices.
Does a nofollowed link pass link equity?
For Google, nofollow, sponsored and ugc are hints: the link may not pass value, but it may also be used as a signal. It is not correct to say that a nofollow link never counts.
Why are internal links important for link equity?
Because they allow you to distribute authority within the site without depending on external sources. A good internal structure concentrates value on the pages you want to rank.
Do many links on a page reduce the value passed?
Yes, when a page contains many links, the available authority is divided among all destinations. Each individual link therefore receives a smaller share of the total value.
Does topical relevance affect the value of a link?
Yes, a link from a page related by topic tends to pass more value than one from an unrelated context. Topical consistency is therefore a relevant factor.
