Internal PageRank & Link Juice Simulator

PageRank is Google's founding mathematical algorithm (invented by Larry Page and Sergey Brin) designed to measure a web page's authority. It treats links as structural votes: a page that has incoming links is voted for, and it passes a portion of its authority (commonly called "link juice") to all pages it links to. Optimizing your site's internal linking structure ensures that high-authority pages (such as your homepage or main category hubs) channel this authority directly into your critical money pages, boosting their crawl rate and search visibility.

This simulator runs a local, sandboxed random-surfer model using a Google damping factor of 0.85. The algorithm models your site pages as nodes in a directed network graph and translates the links into an adjacency matrix. It then performs a "power iteration" loop (calculating the flowing weight of each page, distributing it along its outgoing links, and repeating the loop up to 25 times). The power iterations continue until the values reach mathematical convergence, representing the absolute probability distribution of a random visitor landing on each page.

An orphan page is a webpage that has zero incoming internal links from other sections of your website. Because search engine crawler spiders (such as Googlebot) discover and index content primarily by tracing the web of links, orphan pages are practically invisible. Even if you submit them inside an XML sitemap, they receive zero internal PageRank authority, resulting in extremely low crawl frequencies, poor index eligibility, and negligible organic search rankings.

A sink page (or PageRank dead end) is a webpage that has incoming links but contains absolutely zero outbound links pointing to other pages on your domain (e.g. a conversion landing page with all headers and footer menus removed). In mathematical network flows, sinks absorb link juice from the rest of the site but never redistribute it. Sinks drain PageRank from the overall network, reducing the total available authority circulating through your site. You should configure minimal utility or home nav links on all pages.

A silo internal linking architecture (also known as topical clustering) organizes a website's content into distinct thematic compartments. Pages within a specific silo link heavily to each other and to the parent category page, but rarely link across to pages in other unrelated silos. This structure keeps link juice tightly contained within specific topical groups, building high topical authority and signaling to search engines exactly which pages represent the definitive resources for specific search intents.

Historically, developers used `rel="nofollow"` on internal links to prevent passing PageRank to low-value pages like privacy policies. However, Google long ago updated its PageRank algorithms. Today, using nofollow on internal links does not preserve authority; instead, the link juice allocated to that link is simply discarded and evaporates. To keep PageRank circulating fully, do not nofollow internal links. Instead, use standard links, and if a page truly shouldn't index, apply a `noindex` robots meta tag.

Yes, absolutely. The Link Juice Simulator runs 100% locally client-side inside your browser sandbox. The CSV dataset, page names, and calculated adjacency matrix scores are processed in local volatile RAM and are never transmitted over the network or logged on FlowStack servers. This local pipeline allows you to paste complete site crawl structures or proprietary sitemap linkages completely offline with absolute security.
