Link equity is the ranking value that a hyperlink passes from the linking page to the page it points to. In SEO, within links and authority, link equity explains why a link from a trusted, relevant page helps a target rank more than a link from an obscure or unrelated one, and why the same link can be worth more or less depending on where and how it is placed.
The concept is often called link juice in informal usage. It descends from the original PageRank idea, in which a page’s importance flows through its outgoing links to other pages, but modern search engines combine it with many relevance and trust signals and never expose an exact value.
How link equity flows between pages
In the PageRank model, each page holds an importance score and divides it among its outgoing links. A page that receives links from many important pages accumulates a high score, and part of that score then flows onward. A damping factor, classically described as about 0.85, models the chance that a random surfer keeps clicking rather than jumping elsewhere, so equity diminishes with each hop.
Modern ranking systems refine this simple division. A link in the main content is widely believed to carry more weight than one in a footer or sidebar, and a link that users are likely to click is treated as more meaningful than a buried one. The exact formulas are not public, so practitioners reason in terms of relative strength, not numbers.
Link equity flows both from external backlinks into a site and through internal links within it. Internal linking therefore decides how the equity that a homepage or a popular article receives is distributed to deeper pages.
Factors that determine link equity
No single factor decides how much equity a link passes. The following table lists the factors that practitioners consistently consider and how each one tends to affect value.
| Factor | Higher equity when | Lower equity when |
|---|---|---|
| Authority of the linking page | The page itself earns many quality links | The page is new, orphaned or weakly linked |
| Topical relevance | Linking site covers a related subject | Topic is unrelated to the target |
| Link placement | Editorial link inside the main content | Boilerplate footer, sidebar or widget link |
| Number of outgoing links | Page links to few other pages | Page links to hundreds of destinations |
| Anchor text | Descriptive and natural | Generic or over-optimized exact match |
| Link attributes | Normal followed link | Nofollow, sponsored or user-generated qualifier |
| Crawlability | Plain HTML link that is easy to discover | Link only reachable after complex scripts |
These factors interact. A highly authoritative page that is off-topic and links to hundreds of sites may pass less useful equity than a modest page from a closely related niche that links editorially to only a few sources.
Link attributes and redirects
Link qualifiers tell search engines how to treat a link. Since the change to a hint-based model, nofollow, sponsored and ugc are signals that engines may consider rather than strict commands, but in practice they sharply limit the equity a link passes.
| Link type | Intended meaning | Typical effect on equity |
|---|---|---|
| Followed link | Editorial endorsement | Passes equity normally |
| rel=”nofollow” | No endorsement intended | Treated as a hint; usually little or no equity |
| rel=”sponsored” | Paid or affiliate placement | Should pass no ranking credit |
| rel=”ugc” | User-generated content such as comments | Usually little or no equity |
| 301 or 308 redirect | Permanent move | Equity is consolidated on the target |
| 302 or 307 redirect | Temporary move | Treated as permanent if kept for a long time |
A long-held belief was that 301 redirects lose a share of equity. Search engines have stated that permanent redirects no longer reduce PageRank, but redirect chains still waste crawl effort and risk breaking, so links should point to the final destination where possible.
Preserving and distributing link equity
Link equity is easiest to lose during site changes. Migrations, URL restructuring and content pruning can cut off pages that hold valuable backlinks, and the equity disappears if those URLs return 404 errors without redirects.
- Redirect every retired URL that has backlinks to its closest relevant replacement, not to the homepage by default.
- Reclaim lost links by asking webmasters to correct broken URLs that point to the site.
- Link internally from strong pages to commercially important pages that attract few external links.
- Consolidate duplicates with canonical URLs so that equity is not split across variants.
- Keep important pages within a few clicks of the homepage so equity does not thin out over long paths.
The older practice of PageRank sculpting, where internal links were nofollowed to concentrate equity, no longer works as intended. The equity assigned to a nofollowed link is not redistributed to the remaining links, so the technique only wastes value.
Misconceptions and risks around link equity
Third-party authority metrics are estimates built by tool vendors, not search engine values. They are useful for comparing sites, but treating them as the actual measure of link equity leads to poor decisions, such as rejecting relevant links from small sites.
| Misconception | Reality | Practical consequence |
|---|---|---|
| More links always mean more equity | Quality and relevance outweigh volume | Focus on earning editorial links |
| Vendor authority score is equity | It is a third-party approximation | Judge links by relevance and context too |
| Bought links are a shortcut | Paid links that pass equity violate guidelines | Risk of manual action and devalued links |
| Equity never fades | Removed or changed links stop passing value | Monitor important backlinks over time |
Manipulating link equity through link schemes, such as large-scale guest posting for links, private blog networks or link exchanges, can result in devalued links or manual actions. Durable equity comes from content and assets that others choose to cite.
In plain words
Link equity works like a recommendation from someone you trust. When a respected expert mentions a shop, people take the shop more seriously. When an unknown stranger does, it counts for much less.
Search engines treat links in a similar way. A link from a trusted and related website gives a page more weight than a link from a random one. Websites also pass this value between their own pages, so good internal links help less visible pages benefit from the popular ones.
A real-world example
A software company publishes an original research report on remote work habits. Over a year, the report earns links from around 40 industry publications, and it becomes one of the most linked pages on the domain. The product pages, however, attract almost no external links and rank on the third page of results.
The SEO team adds contextual internal links from the report to the two most relevant product pages, using descriptive anchor text, and links the report from the main navigation of the resources section. During a later site migration, they map every old report URL with a 301 redirect to its new address so that none of the backlinks are lost.
Over the following months, both product pages move to the first page of results for their main queries, while the report keeps its rankings through the migration.
