What Is Link Equity?
Written byFlavio Amiel Founder, Roborank
Link equity is the ranking value that a hyperlink passes from the linking page to the page it points to. Often called link juice, it flows according to the linking page’s own authority, its relevance, and how many other links share the page. Equity moves through both external backlinks and internal links, and certain link attributes can stop it from passing.
- Link equity is the authority a link transmits; it descends directly from the PageRank idea that links pass value weighted by the linking page’s strength.
- A page splits its equity across all its outbound links, so one link from a page with few links passes more than one from a page stuffed with links.
- Internal links pass equity too, letting you route authority from strong pages to pages that need to rank — often the fastest lever you control.
- The rel=nofollow, rel=sponsored, and rel=ugc attributes signal that a link should not pass equity; since 2020 Google treats them as hints rather than strict directives.
How Link Equity Works
Link equity is the ranking value that travels along a hyperlink from the page giving the link to the page receiving it. The term is the professional successor to “link juice,” and both name the same idea: links are not just navigation, they are transfers of authority. When a strong page links to yours, some of its standing flows to you, and search engines factor that inherited authority into how they rank the receiving page.
The concept descends directly from PageRank, the algorithm that founded Google. PageRank modeled authority as something that flows through the web’s link structure — a page accumulates value from the pages linking to it and passes value along to the pages it links out to. Link equity is the practical, everyday name for that flow. You do not need the exact math to work with it; you need to understand the direction and the leaks.
Three factors govern how much equity a link carries. The authority of the linking page is the biggest: a link from a strong, widely-cited page passes far more than a link from an obscure one. Relevance matters — a link from a topically related page is worth more than one from an unrelated context. And the number of links on the source page dilutes the share, because a page divides its equity across every link it contains. A link that is one of five passes more than a link that is one of two hundred.
What Controls the Flow of Link Equity
Equity does not flow freely everywhere. Several mechanisms open, restrict, or block it:
- Follow vs nofollow. A standard followed link passes equity. A link marked
rel="nofollow",rel="sponsored", orrel="ugc"signals that it should not — used for paid links, user-generated content, and untrusted destinations. - Internal links. Links between pages on your own site pass equity just as external ones do, which is what lets you route authority from strong pages to weak ones through internal linking.
- Redirects. A 301 permanent redirect passes nearly all of a page’s equity to the new URL. Redirect chains and loops leak value at every hop.
- Broken and orphaned targets. Equity aimed at a 404 page is wasted, and an orphan page with no internal links receives none at all.
The practical takeaway is that link equity is a system you plumb, not just a total you accumulate. Where it pools and where it drains is often more actionable than how much you have.
Example of Link Equity
The clearest documented moment in how link equity is controlled is Google’s overhaul of the nofollow attribute. On September 10, 2019, Google published Evolving “nofollow” — new ways to identify the nature of links, the single best primary source on how equity is allowed or blocked from passing.
The change was concrete and dated. Google introduced two new attribute values alongside the original: rel="sponsored" to mark paid or advertising links, and rel="ugc" to mark links in user-generated content like comments and forum posts. rel="nofollow" remained for links you don’t want to vouch for at all. The deeper shift was philosophical: Google announced that from that point it would treat all three attributes as hints for ranking purposes rather than strict directives. As the post spelled out, nofollow began influencing crawling and indexing as a hint on March 1, 2020, while it started counting as a hint for ranking on the same date.
Why this is the perfect worked example: it shows that link equity is real enough that Google built explicit, evolving controls for it. The original nofollow existed precisely because links pass value and that value was being manipulated — think comment spam and paid links. The 2019 update refined the controls so publishers could describe why a link exists without necessarily throwing away all of its signal. When you place a followed link, you are choosing to pass equity; when you add sponsored or ugc, you are telling Google not to. That is link equity management in its most literal form, documented by the search engine itself.
The mechanism underneath all of it is still the 1998 PageRank model: authority flows across links, weighted by the source and split across the outbound set. Every attribute, redirect rule, and internal-linking decision is just a way of steering that flow.
The mistake I correct most often is teams treating every link as equal and every page as a sealed box. Neither is true. Link equity flows, and it flows unevenly — most sites concentrate their earned authority on a handful of pages (usually the homepage and a few hero posts) while the pages that actually need to rank sit starved at the edge of the site. Before I chase a single new backlink for a client, I look at where the equity they already have is pooling and whether it can reach the pages that matter through internal links. Redirect chains leak it, orphan pages never receive it, and a nofollowed link never sends it. You can often move rankings just by re-plumbing the flow you already own, no outreach required.

The Bottom Line
Link equity is the currency links carry: the authority a page hands to whatever it points at, scaled by its own strength and divided across its outbound links. It moves through external and internal links alike, gets blocked by nofollow-style attributes, and drains through sloppy redirects. Manage where it flows — not just how much you earn — and you control a lever most sites leave idle.
