Your site’s most important pages might be starved of ranking power simply because nothing links to them - while throwaway pages soak up authority they’ll never use. That imbalance comes down to link equity: the ranking power that one page passes to another through a hyperlink. Some people still call it “link juice.” Whatever you call it, the concept is straightforward: when page A links to page B, page A is vouching for page B, and Google transfers a portion of page A’s authority along with that vote. The more authority the linking page has, the more link equity it passes.

This is one of the foundational mechanics of how Google ranks pages. PageRank - the original algorithm Larry Page built - was essentially a system for calculating and distributing link equity across the entire web. The algorithm has evolved dramatically since 1998, but the core principle hasn’t changed: links are votes, and votes from powerful pages count more.

Link equity flows in one direction: from the linking page to the linked page. Every outbound link on a page shares a portion of that page’s authority. The critical detail most people miss is that link equity gets divided among all outbound links on the page.

Say a page with strong authority has 5 outbound links. Each link receives roughly one-fifth of the available equity. Now imagine that same page has 200 outbound links. Each link gets a tiny sliver. This is why a link from a resource page with 15 carefully curated links is worth far more than a link from a directory page with 500 listings.

External links and internal links both pass link equity, but they work differently in practice.

External links bring new authority into your site from the outside. A link from a high-authority domain like Reuters or a respected industry blog injects equity you didn’t have before. This is why backlink acquisition is such a big deal in SEO - it’s the primary way to increase the total pool of link equity flowing through your site.

Internal links don’t create new equity. They redistribute what you already have. Think of your site’s total link equity as water in a system of pipes. External links are the faucets that bring water in. Internal links are the pipes that route it to specific rooms. If your most important pages aren’t connected to the rest of your site through internal links, the water never reaches them.

For a deeper breakdown of how different types of backlinks contribute varying levels of equity, that guide covers the spectrum from editorial links down to directory submissions.

Not every link passes equity. Several things can stop or reduce the flow.

Nofollow attributes. Adding rel="nofollow" to a link tells Google not to pass ranking equity through it. Google introduced this in 2005 to combat comment spam. Since 2019, Google treats nofollow as a “hint” rather than a directive - meaning they might still pass some equity through nofollow links - but in general, a nofollow link passes significantly less equity than a standard followed link. Sponsored links (rel="sponsored") and user-generated content links (rel="ugc") behave similarly.

Redirect chains. A single 301 redirect preserves most link equity. Google’s John Mueller has said 301s don’t lose PageRank. But stack three or four redirects in a chain and things get murky. Each hop introduces a chance of equity loss, and long chains can also slow crawl discovery. Clean up redirect chains so every URL resolves in one hop.

302 redirects. Historically, 302 (temporary) redirects didn’t pass equity the way 301s (permanent) did. Google has gotten better at handling this, but using a 302 when you mean 301 is still a needless risk. If the redirect is permanent, use 301.

Noindex pages. If a page is noindexed, Google will eventually stop passing equity through its outbound links. The page drops out of the index, and its links lose their power. This catches people off guard when they noindex thin category pages that happen to link to important product pages.

Broken links. A link pointing to a 404 page passes zero equity. That equity essentially evaporates. If high-authority pages are linking to URLs on your site that no longer exist, you’re leaking equity that should be boosting your rankings. Set up 301 redirects for any dead URLs that have backlinks.

HTTP to HTTPS issues. If your site migrated to HTTPS but some external links still point to HTTP URLs without proper redirects, you could be losing equity from those links. Make sure HTTP versions 301 to their HTTPS equivalents.

This is where you have the most control, and where most sites leave the most on the table.

Your homepage almost always has the highest page authority on your site because it receives the most external backlinks. Every page linked from your homepage gets a portion of that equity. Pages two clicks from the homepage get less. Pages buried four or five clicks deep get almost nothing.

The practical implication: your most important pages should have the most internal links pointing to them from the most authoritative pages on your site.

Here’s what good internal link equity distribution looks like:

Flat site architecture. Keep important pages within two or three clicks of the homepage. Deep nesting starves pages of equity. If your highest-revenue product page is five clicks deep behind two category filters and a pagination wall, it’s not getting the equity it needs to rank.

Hub-and-spoke linking. Build topic clusters where a central pillar page links to related supporting articles, and those articles link back to the pillar. This concentrates equity on the pillar page while keeping supporting content connected. It also signals topical relevance to Google, which reinforces the equity that flows through those links.

Strategic sidebar and footer links. Site-wide links in navigation, sidebars, and footers pass equity to every page they point to. Use these slots for pages you genuinely want to rank - your core product pages, top conversion pages, or cornerstone content. Don’t waste them on your privacy policy.

Contextual links within body content. Links placed naturally within article text pass more equity (and more relevance signals) than navigational links. When you mention a related topic in a blog post, link to it. This is also the best kind of link for readers, which makes it a double win.

Stop thinking about link equity as something abstract. Treat it as a resource you’re allocating.

Audit your internal link structure regularly. Use Screaming Frog or Sitebulb to crawl your site and identify orphan pages (no internal links pointing to them), pages with thin internal link profiles, and your most-linked pages. Make sure the pages receiving the most internal links are the pages you actually want to rank.

Fix broken backlinks. Export your backlink profile from Ahrefs or Search Console. Filter for links pointing to 404 URLs. Set up 301 redirects to the most relevant live pages. This is free equity recovery - the links already exist, you just need to catch the flow.

Be deliberate about outbound links. Every external link on your page shares a portion of your equity with someone else’s site. That’s fine when you’re citing sources or linking to genuinely useful resources. But don’t scatter external links carelessly. Fifty outbound links on a page dilute the equity flowing to each one.

Consolidate thin pages. If you have ten weak pages targeting similar keywords, consolidate them into one thorough page and redirect the old URLs. The combined equity from all inbound links - both internal and external - flows to the consolidated page, giving it a much better shot at ranking.

Use your keyword clustering tool to find consolidation opportunities. Grouping your keywords by semantic similarity reveals where you’ve spread content too thin across multiple pages that could be a single, stronger piece.

Prune noindex pages carefully. Before noindexing a page, check whether it has external backlinks. If it does, redirect it instead. Noindexing a page with backlinks destroys the equity those links were providing.

Here’s the part that people forget: your internal link equity is finite. When you add a new internal link to a page, you’re not creating equity from nothing. You’re redirecting it away from other links on that page. Adding fifty internal links to your homepage doesn’t create fifty new streams of equity - it splits the existing equity into fifty thinner streams.

This means every internal link should be intentional. Link to pages that matter. Remove or nofollow internal links to pages that don’t need to rank (login pages, thank-you pages, admin sections). The goal is to channel the maximum amount of equity toward the pages driving your organic traffic and conversions.

Link equity isn’t complicated once you stop treating it as a mystery. It’s authority flowing through links, divided among recipients, blocked by certain attributes, and shaped by your site’s architecture. You control more of it than you think - especially on the internal side, where every link is your decision to make.
