Internal Link Equity Calculator — PageRank Flow & Silo Distribution Modeler

Simulate internal PageRank transfer, optimize crawl depth, eliminate orphan pages, and route equity to high-converting money pages.

The Mathematical Flow of Internal PageRank & CheiRank

While external backlinks inject new link equity into a domain, Internal Linking is the control mechanism that distributes that equity across your website’s pages. The mathematical foundation governing internal link equity is based on Google’s classical PageRank formula with a standard damping factor ($d = 0.85$):

PR_{passed}(Destination) = rac{PR(Source) imes 0.85}{N_{outbound}}

If a high-authority pillar page with a PageRank score of 74 contains 100 outbound links, each linked destination receives less than 0.63 points of equity. However, if the page is optimized to link out to only 20 tightly relevant cluster subpages, each receiving page captures 3.14 points of link juice—a 500% increase in ranking power.

Internal Linking Architecture Comparison Matrix

Architecture Model Link Flow Mechanism Crawl Depth & Equity Efficiency Best Use Case
Strict Topic Silo Links contained strictly within relevant topic category clusters. Maximum topical authority & zero equity bleed. Large resource platforms & financial tool hubs.
Hierarchical Pyramid Home → Category → Subcategory → Article/Product. Structured crawl depth; moderate equity dilution on level 4+. E-commerce websites & enterprise publishers.
Unstructured Flat / Random Articles cross-link randomly without category boundaries. High equity leakage; creates orphan pages and low crawl budget. Small personal blogs (< 20 pages only).

Funnel internal links from high-DR backlink earners directly to target money pages.
