What is Link Equity (Link Juice) in SEO?

Link equity is the ranking value passed from one page to another through hyperlinks. When a page links to another page, it shares a portion of its authority with that destination. This is sometimes called "link juice" or, more formally, PageRank. Search engines use it as one of the core signals for determining how much authority a page deserves in their rankings.

Understanding link equity is not just about building backlinks. It is about making sure the authority you earn externally is distributed correctly across your own site, and that none of it is being silently wasted through technical issues.

How does link equity flow through a site?

Link equity enters your site through external backlinks. When a high-authority external page links to one of your pages, it passes a portion of its authority to you. The more authoritative the linking page, and the fewer other outbound links it has, the more equity your page receives from that link.

Once equity is inside your site, internal links are the mechanism that distributes it. A page with strong external links pointing to it can pass equity through to deeper pages via internal links. This is why internal linking strategy matters: the pages you link to from your most-linked pages receive a share of that authority.

The key principle is that equity divides. If a page has 100 units of equity to pass and links to five pages, each destination receives roughly 20 units. A page that links to fifty destinations passes a much smaller share to each one. This is why linking from focused, relevant pages is more valuable than linking from pages with hundreds of outbound links.

What determines how much equity a link passes?

Several factors affect how much equity a link actually transfers:

Authority of the source page. A link from a page with many high-quality inbound links passes more equity than a link from a page with none. This is not about the domain as a whole, it is page-level. A homepage typically has more authority than a deep archive page on the same site.

Number of outgoing links on the source page. As above, equity divides across all outbound links. A page linking to three destinations passes more per link than a page linking to a hundred.

Followed vs nofollowed. A rel="nofollow" attribute on a link tells Google not to pass PageRank through it. Google's current guidance treats nofollow as a hint rather than a directive, but in practice, followed links reliably pass equity and nofollowed links do not. Sponsored and UGC attributes behave similarly.

Relevance of the linking page. Google uses topical relevance as a quality signal. A link from a relevant, topically related page is treated as more meaningful than a link from an unrelated one, even if the raw authority is similar.

Placement within the content. Links in the main body of a page carry more weight than links in footers, sidebars, or boilerplate navigation. Google has confirmed that placement is a factor in how it evaluates links.

How do redirects affect link equity?

Redirects are where link equity quietly leaks from many sites.

A 301 (permanent) redirect passes the majority of link equity from the old URL to the new one. Google's official position is that 301s pass full PageRank, though in practice there can be a small delay before the full equity is transferred.

A 302 (temporary) redirect is less reliable. Google may or may not consolidate equity through a 302, because technically the original URL is supposed to return. For permanent moves, always use a 301.

Redirect chains are the bigger problem. A chain is when URL A redirects to URL B, which redirects to URL C. Each hop in the chain reduces the equity that arrives at the final destination. A chain of three or four hops can lose a significant portion of the original equity. Chains also waste crawl budget and slow down page resolution for users.

How to fix redirect chains covers the process of collapsing these. For a primer on what 301s are and when to use them, see what is a 301 redirect.

How do you preserve link equity across a site?

The main ways equity gets wasted on technically well-intentioned sites:

Internal links pointing to redirected URLs. If your internal navigation links to /old-page/ which 301s to /new-page/, equity is flowing through that redirect on every crawl. Update the internal link to point directly to the final URL and you remove the unnecessary hop.

Broken internal links. A link to a 404 page passes no equity. Googlebot follows the link, hits a dead end, and moves on. These pages also create a poor user experience and waste crawl budget.

Redirect chains in internal links. These compound the problem. A chain in an external backlink is bad; a chain in an internal link is something you have direct control over and can fix today.

Pages that receive no internal links. A page that exists on your site but receives zero internal links is an "orphan page." Even if that page earns external backlinks, it contributes nothing to the rest of the site's link graph. These pages also tend to be crawled infrequently. Auditing internal links regularly surfaces these. The internal links audit guide explains how to do this systematically.

How do you build link equity?

Earning backlinks from high-authority, relevant external pages is the only way to increase the total amount of equity flowing into your site. The mechanisms are covered in what is link building, but the equity angle has some specific implications worth noting:

A single link from a page with genuine authority passes more equity than dozens of links from low-authority pages. Quality over quantity is not just an abstract principle: it is baked into how PageRank mathematics work.

The pages that earn external links are not always your most commercially important pages. A popular guide or research piece may attract many links while your product pages attract few. Internal linking from those high-equity guide pages to your commercial pages is how you route earned authority where you need it.

Domain authority is a third-party metric that approximates how much accumulated link equity a domain has. It is not a Google metric, but it is useful as a directional signal for evaluating potential link sources.

How do you audit link equity distribution?

The goal of a link equity audit is to find where authority is entering your site, confirm it is being distributed sensibly, and identify where it is leaking.

Check for redirect chains in internal links. A site crawler will flag internal links that resolve through one or more redirects. Update these to point to the final URL.

Identify orphan pages. Pages with no internal links are invisible to Googlebot from within your site. A crawler that maps your internal link graph will surface these. For a full methodology, see how to audit internal links.

Review your internal link distribution. Which pages receive the most internal links? Are your highest-priority pages also the ones receiving the most internal link equity? If your homepage and a handful of blog posts are the only well-linked pages, your product or service pages may be underserved.

Review your backlink profile. Understanding where equity is entering your site from external sources helps you decide which pages to build internal links from. A backlink audit is the starting point.

Check for nofollow on internal links. Internal nofollows are rarely intentional and they block equity from flowing to the linked page. They appear occasionally as a result of CMS templates or plugin defaults.

Link equity is not something you can see directly: you infer it through rankings, backlink data, and crawl analysis. The practical work is making sure equity earned from external backlinks reaches your most important pages through clean, direct internal links, and that nothing is silently leaking through redirect chains, broken links, or orphaned pages.

Download Crawly to audit your internal links. Crawly shows you which internal links pass through redirects so you can update them to point directly to final URLs, and identifies orphan pages that are cut off from your site's link equity flow.
