Link Equity Explained: How Authority Flows Through Your Website

Link equity explained simply: it's the authority that passes from one page to another every time a hyperlink connects them, and it's still the mechanism deciding which of your pages Google trusts enough to rank. The concept traces back to Google's original PageRank algorithm, published by Larry Page and Sergey Brin in 1998, and the core idea hasn't changed since.

Picture a page as a jug of water. Every link on that page pours out a portion of what it holds. The more links crowded onto the page, the smaller each individual pour becomes. DomCop's explainer uses that exact analogy for how this authority distributes, and it explains a surprising number of ranking mysteries once you actually see it.

Link equity flows through both external backlinks and internal links, but most site owners only think about the external half. Internal linking is where you actually control the flow, and poor internal structure can waste authority that expensive backlinks worked hard to earn.

This guide breaks down how link equity moves through a site, what determines how much of it a given link passes, and the specific leaks that quietly waste authority most sites never notice.

01What Link Equity Actually Is

Rhino Rank's 2026 guide defines it precisely: link equity is the authority, trust, and ranking power that passes from one page to another through a hyperlink. When Page A links to Page B, a portion of Page A's accumulated value transfers to Page B, and search engines treat that as a vote of confidence.

The informal term "link juice" showed up as SEO shorthand in the early 2000s, and it stuck because it describes the mechanism well, authority flows through links the way liquid flows through pipes. Link equity is the cleaner, more technical term most SEO teams use for the same idea today.

02How Link Equity Flows Through Internal Links

SEOShouts' breakdown of internal flow patterns lays out the dilution principle clearly: equity divides among all dofollow outgoing links on a source page. A page with 5 outgoing links gives each destination roughly 20% of its equity. A page with 50 outgoing links gives each destination roughly 2%.

That single mechanic explains why a Zyppy study of 23 million links found traffic peaking at 45 to 50 links per page, SEOShouts' analysis notes. Beyond that threshold, each individual link passes so little equity it barely registers for the destination page.

03What Determines How Much Equity a Link Passes

Pielab's guide identifies the factor most people overlook first: not all links pass value the same way. Links from authoritative, topically relevant websites typically transfer more equity than links from low-quality or unrelated sources.

Link type matters just as much as source quality. Dofollow links pass equity normally, the standard type used in backlink building. Nofollow links, by contrast, instruct search engines not to consider them for ranking purposes, so they don't pass meaningful equity even when they still drive referral traffic, a distinction LinksThatRank's guide emphasizes when auditing which backlinks are actually worth pursuing.

04The Reasonable Surfer Model: Why Placement Matters

SEOShouts' analysis, referenced above, points to a refinement Google made to the original PageRank concept: the Reasonable Surfer model assigns more weight to links users are actually likely to click. A contextual link sitting in the first paragraph of body content passes more equity than an identical link buried in a footer.

ClickRank's PageRank guide reinforces the same principle from a different angle: links placed prominently within main content usually carry more weight than links hidden in sidebars or navigation, since editorial context signals genuine relevance rather than a boilerplate placement.

06Common Link Equity Leaks Worth Fixing

SEOShouts' guide, referenced above, calls these equity leaks: pages or links that waste authority instead of routing it productively. Every site has them, and finding the leaks is often faster than building new backlinks to compensate.

Broken internal links are the most common leak. Semrush's analysis of 10 million pages found the average website carries 5 to 15 broken internal links, and each one sends equity into a dead end. The source page still spends one of its link slots on that broken link, reducing what flows to working destinations, while the broken page itself receives nothing useful.

07How 301 Redirects Pass Link Equity

Practical Ecommerce's technical SEO reference traces the history of this specific question: in 2013, Google's then-webspam lead Matt Cutts confirmed 301 redirects pass most PageRank to a destination page, though not necessarily all of it. In 2016, Google's Gary Illyes clarified that 301 and 302 redirects retain all PageRank.

The same reference adds an important caveat worth remembering: Google has repeatedly stated that 301 redirects may pass little to no link equity for anything other than genuine 1:1 URL replacements, like a redesign or a platform migration, rather than arbitrary redirect chains.

08Link Types and How They Handle Equity

Different link mechanisms handle equity in genuinely different ways, which matters when auditing a site's overall structure.

09Finding and Fixing Broken Internal Links

Here's a practical command-line approach to surfacing broken internal links, plus the correct redirect pattern to recover the lost equity.

# Crawl a site and export all internal links returning 4xx/5xx
screamingfrogseospider --crawl https://example.com \
  --headless --save-crawl \
  --export-tabs "Internal:All" \
  --output-folder ./audit

# Then filter the export for Status Code >= 400
# Each broken URL found is a link equity leak

# Redirect a broken/removed page to its closest live equivalent
Redirect 301 /old-broken-page/ https://example.com/closest-live-page/

# Avoid redirect chains: point directly to the FINAL destination,
# not to another redirect. Each hop in a chain can dilute equity.
