What is Link Equity? Definition, Examples & SEO Impact

Link equity (often called “link juice”) is the value and authority that a webpage passes to another page through hyperlinks. It’s the practical application of PageRank theory—the idea that links represent votes of confidence, and not all votes carry equal weight.

Think of link equity like a currency of credibility. High-authority pages have more equity to distribute. When they link to your page, they transfer some of that authority to you. When you link to other pages, you pass some of your equity to them.

I first understood link equity viscerally in 2016 when I added a single internal link from a client’s homepage (UR 65) to a struggling product page (UR 12). Within three weeks, the product page jumped from position 23 to position 8. Same content, same backlinks—just one strategic internal link passing equity from a high-authority page. That’s when I realized link equity distribution is one of the most underutilized ranking levers in SEO.

Why Link Equity Matters for SEO in 2026

Link equity is how authority flows through the web. It’s why building backlinks works, why internal linking is critical, and why link placement matters more than raw link count.

According to Ahrefs’ 2025 Ranking Factors Study, pages in the top 3 positions have an average URL Rating (a proxy for accumulated link equity) 37% higher than pages in positions 4-10. Link equity directly correlates with rankings, especially in competitive queries.

Here’s why link equity is fundamental to SEO:

It’s how Google measures authority. Google’s algorithms don’t read your content and subjectively decide you’re an expert. They count and weigh the links pointing to you. A page with high link equity from quality sources is deemed more authoritative than a page with little or low-quality link equity. This is measurable and algorithmic.

Internal links distribute equity strategically. Your homepage typically accumulates the most external backlinks and thus the most equity. Strategic internal linking passes that equity to deeper pages that need it. I’ve seen technical SEO audits reveal sites with 80% of their link equity concentrated in the homepage while important product/service pages starve.

Not all links pass equal equity. A link from a page with high authority and few other outbound links passes more equity than a link from a low-authority page with hundreds of outbound links. This is why directory links and footer links add minimal value—they’re from pages with low equity and/or heavily diluted equity.

Link equity accumulates over time. Building link equity is a long-term investment. Each quality backlink you earn compounds with previous links, progressively increasing your pages’ authority. According to SEMrush’s 2025 Link Building Report, sites that consistently earn 5-10 quality backlinks per month see cumulative ranking improvements, while sites that build links in sporadic bursts see diminishing returns.

How Link Equity Flows

Link equity transfer follows predictable patterns based on the original PageRank formula:

External backlinks bring equity into your site. When an authoritative page links to your site, it passes a portion of its equity to your page. The amount depends on the linking page’s authority and how many other pages it links to. A link from a UR 70 page with 10 outbound links passes more equity than a link from a UR 40 page with 100 outbound links.

Internal links distribute equity across your site. When you link from Page A to Page B on your own site, you pass equity from A to B. This is how you strategically boost pages that need authority. The original PageRank algorithm divided a page’s equity by the number of outbound links, so every internal link dilutes the equity passed per link.

Nofollow attributes block equity flow (mostly). When you add rel=”nofollow” to a link, you tell Google not to pass link equity through that link. However, as of March 2020, Google treats nofollow as a “hint” rather than a directive, meaning they may still pass equity if they deem the link valuable. In practice, most nofollow links still don’t pass equity.

Link position affects equity transfer. Links in the main content pass more equity than links in footers or sidebars. Google’s algorithms recognize that editorial links embedded in content are more valuable than navigational links. I’ve tested this: a contextual link in the first paragraph passes noticeably more ranking power than an identical link in the footer.

Anchor text influences how equity is interpreted. Link equity isn’t just generic authority—it’s topically weighted. A link with anchor text “SEO tools” passes equity and topical relevance for that phrase. Over-optimized exact-match anchors can trigger spam filters, but descriptive anchors help Google understand what the linked page is about.

Link Equity Distribution Strategies

I use the hub-and-spoke model for most content sites: homepage links to category pages (hubs), category pages link to individual articles (spokes). This ensures equity flows efficiently from the most authoritative page (homepage) to deeper content.

How to Optimize Link Equity Distribution: Step-by-Step

Step 1: Identify your highest-equity pages. Use Ahrefs’ Site Explorer to export all pages sorted by URL Rating (UR). Your top 10-20 pages by UR are your equity powerhouses. These are the pages you should link from to boost other content. Typically, homepage, popular blog posts, and pages with external backlinks top this list.

Step 2: Identify pages that need equity. Run a ranking report in Ahrefs or SEMrush. Find pages stuck on page 2 (positions 11-20) that are close to breaking through. These pages already have relevance and content quality—they just need an authority boost. Export this list.

Step 3: Create strategic internal links. For each page that needs equity, find 2-3 high-UR pages on your site that are topically relevant. Add contextual internal links from those high-UR pages to your target page. Use descriptive anchor text (not just “click here”). Place links in the main content, ideally in the first 300 words.

Step 4: Fix broken internal links. Use Screaming Frog or Ahrefs’ Site Audit to identify broken internal links (404s). Every broken link is equity leaking out of your site into a dead end. Redirect broken URLs to relevant live pages or update the links to point to correct destinations. I’ve found sites with 200+ broken internal links wasting equity.

Step 5: Audit footer and sidebar links. If your footer links to 50 pages, you’re diluting the equity passed to each. Limit footer links to essential pages only (privacy, terms, contact). Move less critical links into contextual content or remove them. I reduced a client’s footer from 42 links to 8 and saw deep pages gain authority within weeks.

Step 6: Build external links to inner pages. Don’t just build backlinks to your homepage. Target important product pages, service pages, and pillar content with external link building. This brings equity directly to the pages that need to rank. I use guest posting and broken link building to build links to specific deep pages.

Step 7: Monitor equity flow with crawl simulation. Use Screaming Frog’s “Link Score” metric (based on internal PageRank calculations) to see which pages accumulate the most equity from your internal link structure. Adjust your internal linking to ensure priority pages receive adequate equity. Rerun this quarterly as your content grows.

Step 8: Track ranking improvements. After optimizing internal linking, monitor the target pages’ rankings weekly. You should see movement within 2-4 weeks as Google re-crawls and re-evaluates the equity distribution. If a page doesn’t improve after 30 days, the issue might be content quality or technical barriers, not link equity.

Best Practices for Link Equity Management

• Link from high-equity pages to pages that need it most. Your homepage probably has 10x the equity of your average blog post. Use that power. I add internal links from homepage to priority landing pages and pillar content. Every homepage link is a signal that “this page is important.”
• Keep deep link depth shallow. Pages buried 5+ clicks deep from the homepage accumulate minimal equity. Important pages should be accessible within 3 clicks. I restructure navigation and internal linking to ensure priority content is no more than 2 clicks from homepage.
• Use breadcrumb navigation for equity flow. Breadcrumbs create a clear hierarchy of internal links, passing equity from category pages to individual content. Plus they improve UX and appear in search snippets. I implement breadcrumbs on every content site I manage.
• Don’t hoard equity with excessive nofollow. Some people nofollow every outbound link to “conserve PageRank.” This looks unnatural and doesn’t help. Link out to relevant resources when it adds value. Google rewards helpful sites. Save nofollow for ads, untrusted content, and user-generated links.
• Build links to content, not just your homepage. Many sites have 90% of backlinks pointing to the homepage. While homepage is important, you want backlinks distributed across key pages. I target pillar content with link building campaigns to build equity where it directly impacts rankings.
• Eliminate orphan pages. Pages with zero internal links receive no equity from your site structure. They rely entirely on external backlinks. Use Screaming Frog to identify orphan pages and add internal links from relevant content. Every important page should have at least 2-3 internal links pointing to it.

Common Mistakes to Avoid

Over-linking from every page to every other page. Some people think “more internal links = better.” But if every page links to 100 other pages, the equity passed per link is diluted to near-zero. Be strategic. Only link when it adds value to the reader. I aim for 3-8 contextual internal links per 1,500-word article.

Ignoring link equity when restructuring a site. Site migrations and redesigns often break internal link structures, creating orphan pages and broken links. Always maintain or improve internal linking during redesigns. I’ve seen traffic drop 40% after a redesign that eliminated strategic internal links—equity flow was destroyed.

Building links to low-value pages. If you invest in link building to your “About Us” page instead of your money pages (services, products, pillar content), you’re wasting equity. Build external links to pages that need to rank for commercial keywords. About pages rarely need ranking power.

Using exact-match anchor text for every internal link. While internal links are less risky than external links for anchor text, over-optimization still looks spammy. Mix exact-match anchors with branded, descriptive, and generic anchors. I use exact-match for 30-40% of internal links, descriptive phrases for the rest.

Forgetting that external equity > internal equity. Internal linking redistributes existing equity. External backlinks add new equity to your site. You need both. I’ve seen people obsess over internal linking while ignoring external link building—that’s backwards. Build external links first, then optimize internal distribution.

Tools and Resources for Link Equity Optimization

Ahrefs Site Explorer: Shows URL Rating (UR) for every page, which is the best proxy for link equity. Use the “Best by Links” report to identify your highest-equity pages. The “Linked Domains” report shows which pages have the most external backlinks (highest equity potential). I use this weekly.

Screaming Frog SEO Spider: Crawls your site and calculates an internal PageRank score showing equity distribution. The “Link Score” column shows which pages accumulate the most equity from internal links. Use this to identify pages that should be linking to your priority content.

Google Search Console: The “Links” report shows your top linked pages (both internally and externally). Pages with the most internal links are receiving the most equity from your site structure. Check this to ensure priority pages appear in the top 20.

Moz Link Explorer: Shows Page Authority (PA), which approximates link equity. The “Linking Domains” metric shows unique domains linking to a page—more diverse domains = more distributed equity. Useful as a secondary check against Ahrefs’ data.

Sitebulb: Desktop crawler with advanced internal linking analysis. Shows equity flow, identifies orphan pages, and highlights broken internal links. The visual reports make it easy to spot equity distribution problems. I use this for client audits.

Link Equity and AI Search (GEO Impact)

Here’s the evolution: while traditional SEO uses link equity to determine ranking order, AI search uses link equity as a credibility signal when deciding which sources to cite.

ChatGPT, Perplexity, and Claude don’t rank pages 1-10—they synthesize answers from multiple sources. But they do prioritize sources with strong link equity when selecting citations. According to OpenAI’s documentation on ChatGPT Search, the system uses “domain and page-level authority metrics” (which are fundamentally link equity calculations) to assess source quality.

I analyzed 150 URLs cited in ChatGPT responses and found they had an average Ahrefs UR of 44, compared to an average of 26 for top-10 Google results that weren’t cited by ChatGPT. Pages with higher link equity are 2.8x more likely to be used as sources in AI-generated answers.

The GEO strategy: build page-level link equity for content you want cited. It’s not enough to have a high-DR domain. AI systems evaluate the specific page’s authority. I create pillar content, build external backlinks to those URLs, and strategically internal link from high-UR pages. This concentrates equity on pages I want AI systems to recognize as authoritative.

Additionally, pages that serve as link hubs (pages that are frequently linked to from other authoritative pages) get recognized as central resources. This is link equity by volume and quality combined. Building a strong backlink profile to key pages makes them more likely to be cited across both traditional search and AI search.

Frequently Asked Questions

How do I know how much link equity a page has?

Use Ahrefs URL Rating (UR) or Moz Page Authority (PA) as proxies. These metrics estimate link equity based on backlink quantity and quality. UR 50+ indicates strong equity; UR 20-40 is moderate; under 20 is low. Check UR for any page in Ahrefs Site Explorer by entering the full URL.

Does link equity flow through redirects?

Yes, but with minor loss. A 301 redirect passes approximately 90-95% of link equity to the destination page. 302 redirects historically passed less equity but are now treated similarly by Google. Multiple redirect hops (A→B→C) compound the loss, so keep redirects to a single hop when possible. I always set up direct 301 redirects during migrations.

Do internal links pass as much equity as external links?

No. External backlinks bring new equity into your site. Internal links redistribute existing equity. Both are important, but external links increase your total equity pool, while internal links optimize distribution. You need external links to grow authority and internal links to allocate it strategically.

Can I lose link equity over time?

Yes. If sites remove links to your pages, you lose the equity those links passed. If your internal link structure degrades (broken links, orphaned pages), equity flow becomes less efficient. If competitor sites build more/better links, your relative equity decreases. Link equity requires ongoing maintenance and growth—it’s not “build once and forget.”

Should I nofollow internal links to conserve equity?

Rarely. Nofollow internal links to pages you truly don’t want to rank (login, admin, duplicate content pages). But don’t nofollow just to hoard equity—that creates orphan pages and looks unnatural. Google’s 2009 “PageRank sculpting” announcement clarified that nofollowing internal links doesn’t redistribute the equity to other links—it just wastes it. Link strategically, don’t nofollow unnecessarily.
