Not all links are equal. A single link from a respected industry publication can move rankings more than a hundred links from forgotten directories, and a link from your own homepage helps a new page far more than one buried in a footer. SEOs use the term “link equity” (or, less formally, “link juice”) to describe that difference: the value or authority a link passes from one page to another.
Link equity is not a number you can look up in Search Console. It is a mental model based on how Google’s original PageRank algorithm worked and on what Google still says about links today. Understanding it helps you make better decisions about internal linking, redirects, nofollow attributes and which backlinks are worth pursuing.
In this guide you will learn where the concept comes from, which factors influence how much value a link passes, how to preserve equity during site changes and how to direct it to the pages that matter most.
Key Takeaways
- Link equity is the SEO term for the ranking value a link passes from one page to another; it grew out of Google’s original PageRank algorithm.
- Relevance, the linking page’s own strength, link placement and link attributes all affect how much a link is likely to help.
- Internal links are the equity you fully control: use them to push value towards important pages.
- Permanent redirects consolidate signals on the new URL; broken links and long redirect chains waste them.
- Links that are paid or manipulative may be nullified by Google, so they pass no lasting equity.
Where link equity comes from: PageRank
Google’s founders described PageRank in their 1998 paper “The Anatomy of a Large-Scale Hypertextual Web Search Engine”. The idea was that a link is a kind of vote, and votes from important pages count for more. They explained it with an intuitive model:
“PageRank can be thought of as a model of user behavior. We assume there is a “random surfer” who is given a web page at random and keeps clicking on links”
— Sergey Brin and Lawrence Page, The Anatomy of a Large-Scale Hypertextual Web Search Engine
In the formula, each page shares its PageRank across the links going out of it, and a damping factor (which the authors “usually set” to 0.85) models the chance that the surfer keeps clicking rather than jumping to a random page. Two ideas from that paper still shape how SEOs think about equity:
- Strong pages pass more value. A link from a page that itself has many good links is worth more.
- Value is shared among outbound links. A page with a few links gives each one a bigger share than a page with hundreds.
Modern Google is far more complex. Its ranking systems guide says PageRank was “one of our core ranking systems used when Google first launched” and has evolved a lot since. So treat the original formula as a helpful model, not a precise description of today’s systems.
Factors that influence link equity
Google does not publish weights, but its documentation and decades of industry testing point to these factors:
| Factor | Likely effect | Practical takeaway |
|---|---|---|
| Strength of the linking page | Pages with strong link profiles pass more value | Prioritise links from pages that are themselves linked to and visited |
| Topical relevance | Links from related content help Google understand what your page is about | A relevant niche site often beats an unrelated high-score site |
| Link placement | Editorial links in main content are generally treated as more meaningful than boilerplate links | Aim for in-content links, not footer or sidebar placements |
| Number of outbound links | Value is spread across links on the page | A link on a focused article usually beats one on a page listing hundreds |
| Link attributes | nofollow, sponsored and ugc are hints that a link should not pass the usual credit | Expect qualified links to pass little or no ranking credit |
| Anchor text | Describes the target page to users and Google | Use descriptive, natural anchors; see our anchor text guide |
| Link quality and intent | Manipulative links can be nullified | Do not rely on paid or scheme links for equity |
Nofollow, sponsored and ugc
Google asks site owners to qualify outbound links: rel="sponsored" for paid placements, rel="ugc" for user-generated content and rel="nofollow" for other links you do not want to vouch for. Since 2019 Google has treated these attributes as hints rather than strict directives, but you should still assume qualified links pass little ranking credit. Google’s own advice keeps the attribute in perspective:
“Use nofollow only when you don’t trust the source, and not for every external link on your site.”

Our guide to dofollow vs nofollow links explains when each value applies.
Internal links: the equity you control
Most sites have far more internal links than backlinks, and you decide where every one of them points. That makes internal linking the most direct way to manage equity.
- Link from strong pages to important pages. Your homepage and most-linked articles are your best sources of internal equity.
- Keep important pages shallow. Pages reachable in a few clicks from the homepage tend to be crawled and valued more. Our site architecture guide shows how to plan this.
- Fix orphan pages. Google notes that every page you care about should have a link from at least one other page on your site. See how to find and fix orphan pages.
- Use contextual links in body content with descriptive anchors, as covered in our internal linking guide.
How to preserve link equity: a step-by-step process
- Find your most-linked pages. Use Search Console’s Links report and a backlink tool to list the URLs that attract external links.
- Check their status. Any linked URL returning a 404 is wasting equity. Restore the page or redirect it to the closest relevant replacement.
- Use permanent redirects for moved content. Google says permanent redirects are used as a signal that the target should be canonical (Redirects and Google Search). Our comparison of 301 vs 302 redirects explains when to use each.
- Remove redirect chains. Point internal links and redirects straight to the final URL.
- Consolidate duplicates. Use canonical tags or merges so signals are not split between near-identical URLs.
- Reclaim lost links. When a site removes or breaks a link to you, ask for it to be fixed. Our link reclamation guide has templates.
- Pass equity onward with internal links from your most-linked pages to the commercial pages you want to rank.
How to earn more link equity
The sustainable way to grow equity is to create pages other people want to cite. Linkable assets such as original research, tools and in-depth guides attract editorial links over time. Third-party metrics like Domain Authority can help you prioritise prospects, but relevance and real readership matter more.
Shortcuts tend to backfire. Google’s spam updates documentation says that when its systems nullify spammy links, any ranking benefit they generated is lost. That is the core risk with paid niche edits and private blog networks: the equity you pay for may never count, or may disappear later.
| Situation | Equity outcome |
|---|---|
| Editorial link in a relevant article | Best case: likely passes meaningful value |
| Link to a URL that now returns 404 | Wasted until restored or redirected |
| Link through a permanent redirect | Signals consolidated on the target URL |
| Link with rel="sponsored" or "nofollow" | Treated as a hint; expect little ranking credit |
| Paid link without qualification | Violates spam policy; may be nullified or lead to action |
Common mistakes
- Nofollowing internal links to “sculpt” PageRank. This old tactic does not concentrate value the way people hoped; fix your architecture instead.
- Deleting linked pages without redirects. This throws away equity you earned.
- Redirecting everything to the homepage. Irrelevant redirects may be treated like soft 404s; redirect to the closest equivalent.
- Burying key pages. Commercial pages several clicks deep receive little internal equity.
- Chasing equity from irrelevant sites. Relevance matters as much as strength.
- Buying “high-equity” links. Paid links that pass ranking credit break Google’s rules and may be nullified.

Frequently Asked Questions
Is link equity the same as link juice?
Yes. Both terms describe the ranking value a link passes from one page to another. Link equity is simply the more professional-sounding name.
Do nofollow links pass link equity?
Google treats nofollow, sponsored and ugc as hints, so it may use them in some cases, but you should assume they pass little or no ranking credit.
Do 301 redirects pass link equity?
Google uses permanent redirects as a strong signal that the target URL should be canonical, which consolidates signals there. Redirect to the most relevant equivalent page.
Does linking out to other sites leak equity?
Linking to helpful, relevant sources is normal and Google says it is nothing to be scared of. Do not avoid useful outbound links to hoard equity.
How do I see how much link equity a page has?
Google does not show it. Third-party tools estimate page strength from their link indexes, which is useful for comparison but not an exact measure.
Conclusion
Link equity is a model rather than a metric, but it leads to sound decisions: earn relevant editorial links, protect the ones you have with redirects and reclamation, and use internal links to send value where it counts.
