Maintain a tracking list during parsing of Concepts and Entities: * Link Equity: The value and authority passed from one page to another through hyperlinks, historically called "link juice." * PageRank: Google’s original algorithm that calculates a page's importance based on the quality and quantity of its backlinks. * Domain Authority (DA): A Moz metric that predicts how well a website will rank on search engine results pages. * Domain Rating (DR): An Ahrefs metric measuring the overall strength of a website’s backlink profile. * URL Rating (UR): An Ahrefs metric used to simulate the PageRank of a specific referring page. * Link Flow Share: A Market Brew metric that evaluates the relevance and authority characteristics of a link. * Nofollow: An HTML attribute that instructs search engine crawlers not to pass authority or "vote" for a linked page. * Content Cluster: A strategy of publishing multiple related pages to share authority and improve topical relevance.
Link equity is the search engine ranking value and authority transferred from one webpage to another via hyperlinks. Often referred to as "link juice," this concept treats links as votes of confidence that help search engines determine a page's credibility and position in search results.
Both internal links and external backlinks pass this value, though the amount of equity varies based on the linking site’s reputation, relevance, and technical setup.
What is Link Equity?
Link equity represents the "power" a page earns from its link profile. When a high-authority site links to your content, it shares a portion of its authority with you. This process is the core mechanism behind Google’s PageRank, though modern algorithms now use link equity as one of many signals.
While link equity is the value being moved, PageRank is the status result of that movement. [PageRank is the relative importance of a page based on the total link juice it receives] (Ahrefs).
Why Link Equity matters
- Improved Rankings: Pages with higher equity have a better chance of appearing at the top of SERPs.
- Credibility: High-quality backlinks signal to search engines that your content is trustworthy.
- Internal Distribution: You can use internal links to send authority from popular "link-magnet" pages (like reports or studies) to high-value pages that struggle to earn natural links (like product pages).
- Crawlability: Proper link flow ensures search engines find and index all pages on your site.
How Link Equity is Determined
Search engines do not pass equity equally. Several technical and contextual factors dictate how much "juice" flows through a link:
Link Status and Tagging
Only "followed" links pass equity. If a link uses the rel="nofollow", rel="sponsored", or rel="ugc" attributes, search engines ignore them for ranking purposes. Furthermore, [Google sets links in guest posts to nofollow by default] (Rank Math), which prevents them from passing authority.
Site and Page Authority
The "strength" of the linking page is the most significant factor. SEO practitioners use proxy metrics to estimate this value since Google does not share raw PageRank data. Common replacements include [URL Rating (UR) to estimate page-level strength] (Ahrefs) and Domain Authority to gauge the site's overall influence.
Relevance and Context
A link from a fitness blogger to a gym equipment site passes more equity than a link from a cooking blog. Relevance tells Google the "vote" is meaningful. [Link Flow Share measures link equity by analyzing characteristics like relevance to the target page and the context of the link] (Market Brew).
Link Distribution and Placement
Link equity is finite. A page has a set amount of authority to share; the more outgoing links it has, the less equity each individual link receives. Placement also matters: editorial links within the main body text pass more weight than links buried in footers, sidebars, or headers.
Best Practices
Use content clusters. Create a pillar page on a broad topic and link it to several detailed "spoke" articles. This shares equity across the entire topic group and signals topical authority to search engines.
Redirect correctly. Keep your equity during site migrations by using 301 redirects. [Google announced in mid-2016 that no link equity is lost when using 3xx redirects] (Moz), though other search engines may treat temporary 302s differently.
Optimize internal anchor text. Use descriptive, keyword-rich anchor text for internal links. This helps search engines understand the content of the receiving page and boosts its relevance score.
Audit for broken links. Regularly check for 404 errors. A link pointing to a dead page wastes link equity and hurts the user experience.
Common Mistakes
Mistake: Putting all valuable internal links in the footer or sidebar. Fix: Move important links into the body of the content where search engines assign them higher weight.
Mistake: Hoarding "juice" by not linking out to other sites. Fix: Link to authoritative external sources. This does not decrease your own page authority and helps users, which is a positive SEO signal.
Mistake: Linking to irrelevant pages just to share equity. Fix: Only link between pages that share a topical connection. Irrelevant links are devalued and may trigger spam filters.
Mistake: Using nofollow tags on internal links. Fix: Ensure internal links are followed so authority can flow freely to your most important subpages.
FAQ
Are link equity and PageRank the same? No. Link equity is the value that flows through a link, while PageRank is the specific calculation Google uses to determine a page's importance based on that flow. [PageRank considers both the quality and quantity of backlinks] (Rank Math).
Can you measure the exact amount of link equity passed? No. Search engines do not provide these numbers. Practitioners must estimate equity using proprietary tools and metrics like Domain Rating (DR) or Domain Authority (DA).
Do 301 redirects lose link juice? Based on Google's 2016 policy update, 3xx redirects no longer lose PageRank. However, it is still best practice to link directly to a live 200-status page whenever possible to ensure all search engines and crawlers process the link correctly.
Does a page lose its own authority by linking to others? No. Linking to another page is like a recommendation; it does not "drain" the authority of the original page. The only risk is receiving a manual penalty if you link to a large number of spammy or manipulative sites.
Does anchor text affect link equity? Yes. Anchor text provides context. Descriptive text that matches the linked page's content helps search engines assign more value to that link.
