What is Link Juice?

Link juice: the metaphor SEO never retired

Link juice is what practitioners called link equity before "equity" won the conference slide war. The image is simple: authority flows like liquid from a linking page into a linked page. Pour one glass into many cups—each gets less. Block the spout with nofollow—the flow slows or stops, depending on era and interpretation.

The term is imprecise, unmeasurable, and still everywhere. Knowing juice history helps you translate older blog posts, client questions, and toolbar-era habits into modern internal linking strategy.

From PageRank toolbar to modern equity language

Juice vs equity vs PageRank flow

The plumbing metaphors practitioners still use

Metaphors help intuition; they are not specifications. Real ranking systems weight relevance, spam, and engagement—not just fluid dynamics.

Does juice 'evaporate'?

Classic forum debates asked: if a page has three outbound links and two are nofollow, does the third get extra juice?

Historical answer: nofollowed links were often treated as holes where juice disappeared. Modern guidance treats rel attributes as hints. Practical takeaway:

• Do not nofollow internal links to indexable pages you want discovered
• External citations to authoritative sources are normal—do not fear "leaks" on editorial references
• Manipulative sculpting via nofollow footers is obsolete risk

Prefer sound link distribution over juice sculpting.

Internal juice routing

Internal link equity is juice that never leaves your property. High-juice sources on most sites:

• Homepage (nav exports to everything)
• Hub pages with editorial inlinks
• Legacy posts that accumulated backlinks

Low-juice traps:

• Orphan pages with zero internal inlinks
• Paginated archive page 400 with no hub shortcuts
• Thin tag URLs receiving auto-linked juice from related-post plugins

Route juice deliberately through internal linking—not accidental template sprawl.

Juice and PageRank flow

PageRank computes stationary distributions on link graphs—mathematical juice. The algorithm:

• Divides a page's score by its outlink count (simplified)
• Iterates until scores stabilize
• Handles dangling nodes and teleportation

SEO juice talk compresses that math into "strong page links to weak page → weak page might rank better." Directionally true; numerically unknowable from outside Google.

Translating client 'juice' questions

Juice myths from the toolbar era

• Toolbar PageRank was never live Google data for your URL
• Juice is not a currency you deposit once—it is re-evaluated continuously
• More internal links do not create juice—they redistribute it
• nofollow on internal indexable pages wastes discovery signals
• Siloing does not mean zero lateral juice—users cross topics
• Buying juice via paid links violates guidelines

When juice language still helps

Juice metaphors excel in workshops—stakeholders grasp "pour" and "split"—but use link equity in written deliverables.

Juice, relevance, and volume

High-juice links from irrelevant contexts underperform relevant modest links. Link relevance moderates raw flow—a contextual paragraph link from a related pillar beats a site-wide footer from the same source page.

How Crawlox helps juice routing conversations

Crawlox visualizes internal link graphs—reservoirs, orphans, and depth—so "send more juice to X" becomes an actionable inlink report. Track whether hub and pillar updates actually increased paths to priority URLs.

The practical takeaway

Link juice is informal slang for link equity—ranking value passed through links. Understand the history, translate it for stakeholders, and implement routing through internal linking, link distribution, and shallow paths—not deprecated sculpting tricks.
